All Specification Changes will be incorporated into a future version of that specification. 1. Revision of External Battery Specification The estimated life of the external battery when the system is not plugged into an AC power source has been changed. Paragraph 3 of Section 1.8.7, Real-Time Clock, CMOS SRAM, and Battery will be replaced in its entirety as follows: An external coin-cell battery powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of one year. When the computer is plugged in, the 3 V standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 5 V applied. 2. Revision of Section 1.15.5, Adaptec* RAIDport* The name of the Adaptec* RAIDport* card that can be installed in the onboard RAID connector will be changed from Adaptec ARO*-1130CA-B RAIDport card to Adaptec ARO-1130CA RAIDport II card. This card supports only RAID levels 0 and 1. Reference to support for level 0/1 will be removed.  3. Support for 333 MHz Pentium II Processors  The motherboard supports 333 MHz Pentium II processors. Section 1.4, Microprocessor, will be modified to add 333 MHz to the list of supported processor speeds. 333 MHz has been added to the list of speeds that can be selected in the BIOS Setup program configure mode and Table 58, Maintenance Menu, will be updated to include that speed. BIOS revision 4D4KL0X0.86A.0016.P07.9801051509 or later is required for the motherboard to properly support a 333 MHz processor. Note: Higher speed processors may increase system electro-magnetic emissions. It is the responsibility of the system integrator to verify that a system using a 333 MHz processor with this motherboard meets EMC emission standards. 6 DK440LX SPECIFICATION UPDATE ERRATA 1. LS-120 Drive Does Not Work as Expected in Windows* 95 PROBLEM: After restarting Windows* 95 from MS-DOS* mode, the system BIOS does not configure the diskette parameter table correctly if an LS-120 drive is the only floppy drive in the system. IMPLICATION: Windows 95 will report the LS-120 drive as a hard drive instead of a floppy drive and will report a floppy drive available as Drive A. If drive A is subsequently accessed, the system will lock up. The problem does not occur if a 1.44 MB 3-1/2” floppy drive is also present as either drive A or drive B. WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision. 2. Serial Mouse Activity Does Not Wake System After APM Shutdown PROBLEM: The system BIOS does not recognize activity from a serial mouse as an APM event. IMPLICATION: The system will not be restored from a power-managed state until keyboard activity occurs. WORKAROUND: The system BIOS does recognize activity from a PS/2* style mouse. STATUS: This erratum will be fixed in a future BIOS revision. 3. Stuck or Depressed Key During POST May Cause System Hang PROBLEM: The BIOS is unable to detect when a key on the keyboard is stuck or depressed during Power On Self Test (POST). IMPLICATION: If a key is stuck or depressed during POST, the system BIOS will continue to read data from the keyboard, resulting in a system hang condition. WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision. 4. System BIOS Does Not Detect ECC Memory Errors PROBLEM: The system BIOS does not detect when a single or double bit ECC memory error is identified by the memory controller. IMPLICATION: For single bit errors, the error will be corrected based on the memory checkbits. The corrected data will be passed to the system by the controller, but the error will not be signaled to the system BIOS. For double-bit errors identified during run time, no error will be signaled to the system BIOS and the system will not be halted. The erroneous data will be passed to the system by the controller. Because these errors are not detected by the system BIOS, they will not be flagged in the DMI log stored in non-volatile flash memory and the user will not receive information from this log that could be useful in isolating a failing memory module. WORKAROUND: None. 7 DK440LX SPECIFICATION UPDATE STATUS: This erratum will be fixed in a future BIOS revision. 5. Onboard SCSI Controller Identifies Tape Drive as Hard Drive PROBLEM: The onboard SCSI controller may incorrectly identify an attached SCSI tape backup drive as a hard disk drive. IMPLICATION: The tape drive is not accessible, although it appears in the BIOS Setup Boot Menu. WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision. 6. System Cannot Recover BIOS From LS-120 Drive PROBLEM: The permanent system BIOS code stored in the boot block section of the BIOS flash memory device does not include initialization code for the LS-120 drive. IMPLICATION: If the system requires a BIOS recovery because the BIOS was corrupted during an update, that BIOS recovery cannot be performed from an LS-120 drive. An attempt to recover the BIOS from an LS-120 drive, using the BIOS recovery setting of the configuration jumper, will result in a media device error. WORKAROUND: Temporarily replace the LS-120 drive with a standard diskette drive to perform the BIOS recovery. STATUS: This erratum will be fixed in a future PBA revision. 7. SCO* UnixWare* Will Not Install From Onboard SCSI Channel B PROBLEM: The SCSI driver for the SCO* UnixWare* operating system disables Channel B during installation of the operating system. IMPLICATION: An attempt to install from a SCSI device attached to onboard SCSI channel B will fail with the error message: “Warning: adsl: Command timed out.” WORKAROUND: None. STATUS: This erratum will be fixed in a future revision of the SCSI driver. 8. Advanced Power Management May Suspend System During CD- ROM Playback PROBLEM: ATAPI devices (such as CD-ROM and DVD drives) do not reset the inactivity timer that is used by Advanced Power Management to determine when to place the system into suspend mode. IMPLICATION: When playback of an audio CD or a DVD file is the only system activity, the system will go into suspend mode when the inactivity timer expires. WORKAROUND: Temporarily disable the Low-power standby and Shut off monitor options on the Display Properties, Screen Saver menu. This menu is available from the Windows 95 Control Panel. STATUS: This erratum will not be fixed. 8 DK440LX SPECIFICATION UPDATE 9. System Will Not Boot with Network as First Boot Device PROBLEM: The feature allowing the system to boot from the network is not implemented. After the attempt to boot from a network device selected as the first boot device fails, the system BIOS does not attempt to boot from any additional boot devices specified in the BIOS Setup program. IMPLICATION: If Network boot is selected as the first boot device, the system will hang. WORKAROUND: Remove Network boot from the boot sequence. STATUS: This erratum will be fixed in a future BIOS revision. 10. System BIOS Does Not Recognize Hard Drives Larger Than 8.4 GB PROBLEM: The system BIOS does not include hard drive parameters to recognize drives larger than 8.4 GB. IMPLICATION: An installed hard drive larger than 8.4 GB will not be available to the operating system. WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision. 9 DK440LX SPECIFICATION UPDATE SPECIFICATION CLARIFICATIONS The Specification Clarifications listed in this section apply to the DK440LX Motherboard Technical Product Specification (Order Number 682717). All Specification Clarifications will be incorporated into a future version of that specification. 1. Network Operating System May Report Lost Hardware Interrupts Because of an interaction between the Intel 82093AA I/O Advanced Programmable Interrupt Controller (IOAPIC) and the Novell Netware operating system, Novell may post a message to the screen that reports lost or spurious hardware interrupts. These messages and the time required to process them may cause some small increased processor latency, but they have no other impact for the end user. Certain debug hooks built into the operating system may not operate correctly and this could affect application developers. 10 DK440LX SPECIFICATION UPDATE DOCUMENTATION CHANGES The Documentation Changes listed in this section apply to the DK440LX Motherboard Technical Product Specification (Order Number 682717). All Documentation Changes will be incorporated into a future version of that specification. 1. Revision of Section 3.4, PCI IDE Support Section 3.4, PCI IDE Support, will be replaced in its entirety as follows: If Auto is selected as a primary or secondary IDE device (see Section 4.2.2) in Setup, the BIOS automatically sets up the two local-bus IDE connectors with independent I/O channel support. The IDE interface supports hard drives up to PIO Mode 4 and recognizes ATAPI devices, including CD-ROM drives, tape drives and Ultra DMA drives (see Section 6.2 for the supported version of ATAPI). Add-in ISA IDE controllers are not supported. The BIOS determines the capabilities of each drive and configures them so as to optimize capacity and performance. To take advantage of the high-capacity storage devices, hard drives are automatically configured for logical block addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. To override the autoconfiguration options, use the specific IDE device options in Setup. The ATAPI specification recommends that ATAPI devices be configured as shown in Table 54. 2. Revision of Section 6.3, BIOS Beep Codes Section 6.3, BIOS Beep Codes, will be replaced in its entirety as follows: BIOS BEEP CODES Whenever a recoverable error occurs during Power-On Self Test (POST), the BIOS displays an error message describing the problem. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (no card installed or faulty) or if an external ROM module does not properly checksum to zero. An external ROM module (e.g video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device. There are several POST routines that issue a POST Terminal Error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both mono and color adapters). If POST completes normally, the BIOS issues one short beep before passing control to the operating system. 11 DK440LX SPECIFICATION UPDATE Table 78.
