The desktop board supports up to eight USB 2.0 ports via ICH6; four ports routed to the back panel and four routed to two internal USB 2.0 headers. USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds. USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling Hi-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0. 21 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Enhanced IDE Interface The ICH6’s IDE interface handles the exchange of information between the processor and * drives inside the computer. peripheral devices like hard disks, CD-ROM drives, and Iomega Zip The interface supports: • Up to two IDE devices (such as hard drives) • ATAPI-style devices (such as CD-ROM drives) • Older PIO Mode devices • Ultra DMA-33 and ATA-66/100 protocols • Laser Servo (LS-120) drives Serial ATA The desktop boards support four Serial ATA channels via ICH6, connecting one device per channel. Expandability The desktop boards support the following: • Desktop boards D915GAV and D915GEV ⎯ One PCI Express x16 add-in card ⎯ Two PCI Express x1 add-in cards ⎯ Four PCI add-in cards • Desktop boards D915GAG and D915GUX: ⎯ One PCI Express x16 add-in card ⎯ One PCI Express x1 add-in card ⎯ Two PCI add-in cards Related Links: For information about installing the PCI Express x16 card, see page 41 in Chapter 2. BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI Express and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub. The BIOS can be updated by following the instructions on page 59 in Chapter 3. Serial ATA and IDE Auto Configuration If you install a Serial ATA or IDE device (such as a hard drive) in your computer, the auto- configuration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. 22 Desktop Board Features PCI and PCI Express Auto Configuration If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express auto- configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI/PCI Express add-in card. Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup and for booting the computer, with the following restrictions: • The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. • If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. • Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer. Chassis Intrusion The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 22 on page 44 for the location of the chassis intrusion header. Power Management Features Power management is implemented at several levels, including: • Advanced Configuration and Power Interface (ACPI) • Hardware support: ⎯ Power connectors ⎯ Fan connectors ⎯ Suspend to RAM (Instantly Available PC technology) ⎯ Resume on Ring ⎯ Wake from USB ⎯ Wake from PS/2 keyboard/mouse ⎯ PME# wakeup support ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support. 23 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Power Connectors The desktop boards have three power connectors. See Figure 25 on page 49 and Figure 26 on page 50 for the location of the power connectors. Fan Connectors The desktop boards have a 4-pin processor fan header. Desktop boards D915GAV and D915GEV have three chassis fan headers. Desktop boards D915GAG and D915GUX have two chassis fan headers. See Figure 24 on page 48 for the location of the fan headers. ® Fan Speed Control (Intel Precision Cooling Technology) Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the processor thermal diode temperature and adjusts the chassis fan speeds depending on the system temperature. System fan noise may be reduced by operating controlled chassis and processor fans at the minimum necessary speeds. NOTE Not all chassis fan headers on desktop boards D915GEV and D915GAV are controlled. Refer to Table 3 on page 13 to identify controlled chassis fan headers. The processor and chassis fan speed control features can be disabled independently through the desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at full speed if it is not a self controlled fan. It is recommended that processor fan speed control ® remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel boxed processors. Disabling the chassis fan speed control results in chassis fans always operating at full speed. The chassis fan speed control feature should be disabled if a self-controlled chassis fan is attached to any controlled chassis fan header. The overall system noise reduction will vary based on system configuration and environment. Suspend to RAM (Instantly Available PC Technology) CAUTION For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality. CAUTION Power supplies used with this desktop board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory. 24 Desktop Board Features Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up device or event, the system quickly returns to its last known awake state. The desktop board’s standby power indicator, shown in Figure 4, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off. If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. OM16879 Figure 4. Location of Standby Power Indicator Related Links: For more information on standby current requirements for the desktop board, refer to the Technical Product Specification by going to the following link, finding the product, and selecting Product Documentation from the left-hand menu: http://support.intel.com/support/motherboards/desktop/ Resume on Ring The operation of Resume on Ring can be summarized as follows: • Resumes operation from either ACPI S1 or ACPI S3 state • Requires only one call to access the computer • Detects incoming call similarly for external and internal modems • Requires modem interrupt be unmasked for correct operation 25 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Wake from USB NOTE Wake from USB requires the use of a USB peripheral that supports wake from USB. USB bus activity wakes the computer from an ACPI S1 or S3 state. Wake from PS/2 Keyboard/Mouse PS/2 keyboard/mouse activity wakes the computer from an ACPI S1 or S3 state. PME# Wakeup Support When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, or S5 state. Speaker A speaker is mounted on the desktop board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST). Battery A battery on the desktop board keeps the values in CMOS RAM and the clock current when the computer is turned off. Go to page 55 for instructions on how to replace the battery. Real-Time Clock The desktop board has a time-of-day clock and 100-year calendar. The battery on the desktop board keeps the clock current when the computer is turned off. 26 2 Installing and Replacing Desktop Board Components This chapter tells you how to: • Install the I/O shield • Install and remove the desktop board • Install and remove a processor and memory • Install and remove a PCI Express x16 card • Connect the IDE and Serial ATA cables • Connect internal headers • Set up flexible 6-channel audio with jack re-tasking • Connect fans and power cables • Connect PCI bus add-in cards • Set the BIOS configuration jumper • Clear passwords • Locate back panel connectors • Replace the battery Before You Begin WARNINGS The procedures in this chapter assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment.

Removing the Battery 58 3 BIOS The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update utility or the Iflash Memory Update utility, and how to recover the BIOS if an update fails. ® Updating the BIOS with the Intel Express BIOS Update Utility With the Intel Express BIOS Update utility you can update the system BIOS while in the Windows environment. The BIOS file is included in an automated update utility that combines the ® functionality of the Intel Flash Memory Update Utility and the ease-of use of Windows-based installation wizards. To update the BIOS with the Intel Express BIOS Update utility: 1. Go to the Intel World Wide Web site: http://support.intel.com/support/motherboards/desktop/ 2. Navigate to the D915GEV/D915GUX/D915GAV/D915GAG page, click “[view] Latest BIOS updates,” and select the Express BIOS Update utility file. 3. Download the file to your hard drive. (You can also save this file to a diskette. This is useful if you are updating the BIOS for multiple identical systems.) 4. Close all other applications. This step is required. Your system will be rebooted at the last Express BIOS Update window. 5. Double-click the executable file from the location on your hard drive where it was saved. This runs the update program. 6. Follow the instructions provided in the dialog boxes to complete the BIOS update. 59 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Updating the BIOS with the Iflash Memory Update Utility With the Iflash BIOS update utility you can update the system BIOS from a floppy disk or other bootable media. The utility available from the Web provides a simple method for creating a bootable flash memory update floppy that will automatically update your BIOS. Obtaining the BIOS Update File You can update to a new version of the BIOS by using the BIOS update file. The BIOS update file is a compressed self-extracting archive that contains all the files you need to update the BIOS. The BIOS update file contains: • New BIOS files • BIOS recovery files • Intel Flash Memory Update Utility You can obtain the BIOS update file through your computer supplier or by navigating to the Desktop Board D915GEV/D915GUX/D915GAV/D915GAG page on the Intel World Wide Web site at: http://support.intel.com/support/motherboards/desktop Navigate to the D915GEV/D915GUX/D915GAV/D915GAG page, click “[view] Latest BIOS updates,” and select the Iflash BIOS Update utility file. NOTE Review the instructions distributed with the update utility before attempting a BIOS update. The Iflash Memory Update utility allows you to: • Update the BIOS in flash memory • Update the language section of the BIOS Updating the BIOS CAUTION The AUTOEXEC.BAT file provided with the update files updates the BIOS. Do not interrupt the process or the system may not function. 1. Boot the computer with the BIOS update diskette in drive A. During system boot, the AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update process. 2. When the update process is complete, the monitor will display a message telling you to remove the diskette and to reboot the system. 3. As the computer boots, check the BIOS identifier (version number) to make sure the update was successful. If a logo appears, press to view the POST messages. 60 1 1 BIOS Recovering the BIOS It is unlikely that anything will interrupt the BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails. The following procedure uses recovery mode for the Setup program. See page 52 for more information on Setup modes. NOTE Because of the small amount of code available in the boot block area, there is no video support. You will not see anything on the screen during this procedure. Monitor the procedure by listening to the speaker and looking at the diskette drive LED. 1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external peripherals. 2. Remove the computer cover and locate the configuration jumper block (see Figure 28). 3. Remove the jumper from all pins as shown below to set recovery mode for Setup. 4. Insert the bootable BIOS update diskette into diskette drive A. 5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to boot. The recovery process will take a few minutes. 6. Listen to the speaker: • Upon applying power, drive A will begin to show activity. In about a minute, two beeps are heard and drive A activity ceases (temporarily) indicating the successful recovery of the BIOS core. Drive A activity will begin again followed by two more beeps indicating the successful recovery of the boot block. This sequence of events indicates a successful BIOS recovery. • A series of continuous beeps indicates a failed BIOS recovery. 7. If recovery fails, return to step 1 and repeat the recovery process. 8. If recovery is successful, turn off the computer, and disconnect its power cord. 9. Remove the computer cover and continue with the following steps. 10. On the jumper block, reinstall the jumper back on pins 1-2 as shown below to set normal mode for Setup. 11. Leave the update diskette in drive A, replace the computer cover, and connect the computer’s power cord. 12. Turn on the computer and continue with the BIOS update. 61 3 3 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide 62 4 Trusted Platform Module (Optional) The optional Trusted Platform Module (TPM) is a component on the desktop board that is specifically designed to enhance platform security above-and-beyond the capabilities of today’s software by providing a protected space for key operations and other security critical tasks. Using both hardware and software, the TPM protects encryption and signature keys at their most vulnerable stages—operations when the keys are being used unencrypted in plain-text form. The TPM is specifically designed to shield unencrypted keys and platform authentication information from software-based attacks. System Requirements • Intel Desktop Board D915GEV or D915GUX with a Gigabit LAN solution • Microsoft Windows 2000 Professional (SP4) or Microsoft Windows XP Professional (SP1) • NTFS file system required • Microsoft Internet Explorer* 5.5 or later • Adobe* Acrobat* 5.0 or later (included on Intel Express Installer CD) Warning of Potential Data Loss CAUTION Failure to follow the instructions below may cause you to loose data. Read and follow these instructions prior to Trusted Platform Module initialization. System integrators, owners, and end users must take precautions to mitigate the chance of data loss. Data encrypted by any program utilizing the Trusted Platform Module (TPM) may become inaccessible or unrecoverable if any of the following occurs: • Lost Password: Loss of any of the passwords associated with the TPM will render encrypted data inaccessible. No password recovery is available. Read the Security Precautions for Password Procedures. • Hard Drive Failure: In the event of a failure of a hard disk (or other storage media) that contains encrypted data, an image of the hard disk (or other storage media) must be restored from backup before access to encrypted data may become available. The owner/user should backup the system hard disk on a regular basis. Read the Security Precautions below for Hard Drive Backup Procedures. • Platform Failure: In the event of a platform failure and/or replacement of the motherboard, recovery procedures may allow migratable keys to be recovered and may restore access to encrypted data. All non-migratable keys and their associated data will be lost. Both the Infineon* Security Platform software and Wave Systems* EMBASSY* Trust Suite utilize migratable keys. Please check any other software that accesses the TPM for migratability. Read the Security Precautions for Emergency Recovery File Back Up Procedures. • Loss of Trusted Platform Module Ownership: Trusted Platform Module Ownership/contents may be cleared (via a BIOS switch) to allow for the transfer of a system to a new owner. If TPM ownership is cleared, either intentionally or in error, recovery procedures may allow the migratable keys to be recovered and may restore access to encrypted data. Read the Security Precautions for Emergency Recovery File Back Up Procedures. 63 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Security Precautions Security, like any other aspect of computer maintenance requires planning. What is unique about security has to do with understanding who "friends" and adversaries are. The TPM provides mechanisms to enable the owner/user to protect their information from adversaries. To provide this protection the TPM effectively puts "locks" around the data. Just like physical locks, if keys or combinations are lost, the assets (i.e., data) may be inaccessible not only to adversaries, but also to asset owner/user. The TPM provides two classes of keys: migratable and non-migratable. Migratable keys are designed to protect data that can be used (i.e., unencrypted) on more than one platform. This has the advantage of allowing the key data to be replicated (backed-up and restored) to another platform. This may be because of user convenience (someone uses more than one platform, or the data needs to be available to more than one person operating on different platforms). This type of key also has the advantage in that it can be backed-up and restored from a defective platform onto a new platform. However, migratable keys may not be the appropriate level of protection (e.g., the user wants the data restricted to a single platform) needed for the application. This requires a non- migratable key. Non-migratable keys carry with them a usage deficit in that while the key may be backed-up and restored (i.e., protected from hard disk failure) they are not protected against system or TPM failure. The very nature of a non-migratable key is that they can be used on one and only one TPM. In the event of a system or TPM failure, all non-migratable keys and the data associated with them will be inaccessible and unrecoverable. CAUTION The following precautions and procedures may assist in recovering from any of the previously listed situations. Failure to implement these security precautions and procedures may result in unrecoverable data loss. Password Procedures The Infineon Security Platform software allows users to configure passwords from 6 to 255 characters. A good password should consist of: • At least one upper case letter (A to Z) • At least one numerical character (0 to 9) • At least one symbol character (!, @, &, etc.) Example Passwords: “I wear a Brown hat 2 worK @ least once-a-month” or “uJGFak&%)adf35a9m” NOTE Avoid using names or dates that can be easily guessed such as: birthdays, anniversaries, family member names, pet names, etc. All passwords associated with the Infineon Security Platform software (Owner, Emergency Recovery Token, and User passwords) and the Wave Systems EMBASSY Trust Suite are NOT RECOVERABLE and cannot be reset without the original text. The system owner should document all passwords, store them in a secured location (vault, safe deposit box, off-site storage, etc.), and have them available for future use. These documents should be updated after any password changes. 64 Trusted Platform Module Emergency Recovery File Back Up Procedures The Emergency Recovery Token (SPEmRecToken.xml) must be saved or moved to a removable media (floppy, USB drive, CDR, flash media, etc). Once this is done, the removable media should be stored in a secure location. DO NOT LEAVE ANY COPIES of the Emergency Recovery Token on the hard drive or within any hard drive image backups. If a copy of the Emergency Recovery Token remains on the system, it could be used to compromise the Trusted Platform Module and platform. After completing the Infineon Security Platform User Initialization Wizard, a copy of the Emergency Recovery Archive (SPEmRecArchive.xml) should be copied to a removable media and stored in a secure location. This procedure should be repeated after any password changes or the addition of a new user. Hard Drive Image Backup Procedures To allow for emergency recovery from a hard drive failure, frequent images of the hard drive should be created and stored in a secure location. In the event of a hard drive failure, the latest image can be restored to a new hard drive and access to the encrypted data may be re-established. NOTE All encrypted and unencrypted data that was added after the last image was created will be lost. Clear Text Backup (Optional) It is recommended that system owners follow the Hard Drive Image Backup Procedures. To backup select files without creating a drive image, files can be moved from secured programs or drive letters to an unencrypted directory. The unencrypted (clear text) files may then be backed up to a removable media and stored in a secure location. The advantage of the clear text backup is that no TPM key is required to restore the data. This option is not recommended because the data is exposed during backup and restore. 65 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Trusted Platform Module Ownership The Trusted Platform Module is disabled by default when shipped and the owner/end customer of the system assumes “ownership” of the TPM. This permits the owner of the system to control initialization of the TPM and create all the passwords associated with the TPM that is used to protect their keys and data. System builders/integrators may install both the Infineon Security Platform software and the Wave System EMBASSY Trust Suite, but SHOULD NOT attempt to use or activate the TPM or either software package. NOTE System builders should pass the Trusted Platform Module Quick Reference (included with the desktop board) to the system owner to assist them in enabling and initializing the TPM. Enabling the Trusted Platform Module The Trusted Platform Module is disabled by default when shipped to insure that the owner/end customer of the system initializes the TPM and configures all security passwords. The owner/end customer should use the following steps to enable the TPM. 1. While the PC is displaying the splash screen (or POST screen), press the key to enter BIOS. 2. Use the arrow keys to go to the Advanced Menu, select Peripheral Configuration, and then press the key. 3. Select the Trusted Platform Module, press , and select Enabled and press again (display should show: Trusted Platform Module [Enabled]). 4. Press the key, select Ok and press . 5. System should reboot and start Microsoft Windows. Assuming Trusted Platform Module Ownership Once the TPM has been enabled, ownership must be assumed by using the Infineon Security Platform Software. The owner/end user should follow the steps listed below to take ownership of the TPM: 1. Start the system. 2. Launch the Infineon Security Platform Initialization Wizard. 3. Create Owner password (before creating any password, review the Password Recommendations made earlier in this document). 4. Create a new Recovery Archive (note the file name and location). 5. Specify a Security Platform Emergency Recovery Token password and location. (this password should not match the Owner password or any other password). 6. Define where to save the Emergency Recovery Token (note the file location and name). 7. The software will then create recovery archive files and finalize ownership of the TPM. 8. After completing the Infineon Security Platform Initialization Wizard, the Emergency Recovery Token (SPEmRecToken.xml) must be moved to a removable media (floppy, CDR, flash media, etc) if the file was not saved to a removable media during installation. Once this is 66 Trusted Platform Module done, the removable media should be stored in a secure location. No copies of this Emergency Recovery Token file should remain on the system. If a copy remains on the system, it could be used to compromise the security of the platform. 9. Launch the Infineon Security Platform User Initialization Wizard. 10. Create a Basic User password (this password is the most frequently used and should not match any other password). 11. Select and configure Security Platform features for this user. 12. After completing the Infineon Security Platform User Initialization Wizard, a copy of the Emergency Recovery Archive (SPEmRecArchive.xml) should be copied to a removable media and stored in a secure location. This procedure should be repeated after any password changes or the addition of new users. 13. Restart the system. 14. To backup the keys for the EMBASSY Trust Suite, the Key Transfer Manager software must be configured. Launch the Key Transfer Manager from the program menu. 15. Follow the instructions and create and document the locations for both the archive and restoration key files. The key archive should be located on a removable media and stored in a secure location when not in use. 16. Create and document the password to protect the key archive. 17. Provide the TPM Owner password to allow the Key Transfer Manager to create the archive and restoration key files. 18. Upon completing the configuration of the Key Transfer Manager, it will place an icon in the task bar and automatically back up all new and updated keys associated with the EMBASSY Trust Suite. If the removable media that contains the archive file is not present when a new key is generated, then keys will have to be manually backed up using the Key Transfer Manager when the removable media is available. 19. All passwords associated with the Infineon Security Platform Software (Owner, Emergency Recovery Token, and User passwords) and Wave Systems EMBASSY Trust Suite and Key Transfer Manager are not recoverable and cannot be reset without the original text. These passwords should be documented and stored in a secured location (vault, safe deposit box, off- site storage, etc.) in case they are needed in the future. These documents and files should be updated after any password changes. Recovery Procedures How to Recover from Hard Disk Failure Restore the latest hard drive image from backup to the new hard drive – no TPM specific recovery is necessary. How to Recover from Desktop Board or TPM Failure This procedure may restore the migratable keys from the Emergency Recovery Archive, and does not restore any previous keys or content to the TPM. This recovery procedure may restore access to the Infineon Security Platform software and Wave Systems EMBASSY Trust Suite that are secured with migratable keys. 67 Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Requirements • Emergency Recovery Archive (created with the Infineon Security Platform Initiation Wizard) • Emergency Recovery Token (created with the Infineon Security Platform Initiation Wizard) • Emergency Recovery Token Security Password (created with the Infineon Security Platform Initiation Wizard) • Working original operating system (OS) installation, or a restored image of the hard drive • Wave Systems Key Transfer Manager archive password • TPM Ownership password This recovery procedure only restores the migratable keys from the previously created Recovery Archives. 1. Replace the desktop board with the same model as the failed board. 2. Start the original operating system or restore the original hard drive image. 3. Start the Infineon Security Platform Initialization Wizard and check the “I want to restore the existing Security Platform” box. 4. Follow the instructions during the Security Platform Initialization, and append the Emergency Recovery Archive to the existing archive. 5. Provide all the necessary passwords, files, and file locations as requested. It may take up to 20 minutes for Security Platform Initialization Wizard to restore the security platform settings. 6. Start User Initialization Wizard. Select “Recover Your Basic User Key” when prompted. Specify the original Basic User Key password and proceed with the wizard. 7. When re-configuring the Personal Secure Drive, select “I want to change my Personal Secure Drive setting”, confirm the drive letter and name are correct, and then proceed through the rest of the wizard. 8. Restart the system when requested. 9. To restore access to the EMBASSY Trust Suite, right mouse click on the Key Transfer Manager icon located in the taskbar in the lower right corner of the screen, and select Restore TPM Keys. 10.
