It is intended for hardware system manufacturers and software developers of applications, operating systems, or tools. It will contain Specification Changes, Errata, Specification Clarifications, and Documentation Changes. ® ® Refer to the Intel Pentium 4 Processor Specification Update (Order number 249199) for specification updates concerning the Intel Pentium 4 processor and that may apply to the desktop board D845GVSR. Unless otherwise noted in this document, it should be assumed that any processor errata for a given stepping are applicable to the Altered Assembly (AA) revision(s) associated with that stepping. ® Refer to the Intel 845G/845GL/845GV Chipset Specification Update (Order Number 298657) for specification updates concerning the 82845GV GMCH Controller and that may apply to the desktop board D845GVSR. Unless otherwise noted in this document, it should be assumed that any MCH errata for a given stepping are applicable to the Altered Assembly (AA) revision(s) associated with that stepping. ® Refer to the Intel 82801DB I/O Controller Hub 4 (ICH4) Specification Update (Order Number 290745) for specification updates concerning the 82801DB I/O Controller Hub and that may apply to the desktop board D845GVSR. Unless otherwise noted in this document, it should be assumed that any ICH 4 errata for a given stepping are applicable to the Altered Assembly (AA) revision(s) associated with that stepping. Nomenclature Specification Changes are modifications to the current published specifications. These changes will be incorporated in the next release of the specifications. Errata are design defects or errors. Characterized errata may cause the desktop board D845GVSR’s behavior to deviate from published specifications. Hardware and software designed to be used with any given Altered Assembly (AA) and BIOS revision level must assume that all errata documented for that AA and BIOS revision level are present on all desktop boards. Specification Clarifications describe a specification in greater detail or further highlight a specification’s impact to a complex design situation. These clarifications will be incorporated in the next release of the specifications. Documentation Changes include typos, errors, or omissions from the current published specifications. These changes will be incorporated in the next release of the specifications. vi Specification Update for the ® Intel Desktop Board D845GVSR ® Intel Desktop Board D845GVSR Specification Update GENERAL INFORMATION Basic Desktop Board D845GVSR Identification Information AA Revision BIOS Revision Notes C44953-201 VA84510A.86A.0019.P07 1-5 NOTES: 1.

Refer to the Intel Pentium 4 Processor Specification Update (Order Number 249199) for errata related to the Pentium 4 processor and that may apply to the desktop board D845GVSR. ® 4. Refer to the Intel 845G/845GL/845GV Chipset Specification Update (Order Number 298657) for errata related to the 82845GV GMCH that may apply to the desktop board D845GVSR. ® 5. Refer to the Intel 82801DB I/O Controller Hub 4 (ICH4) Specification Update (Order Number 290745) for errata related to the 82801DB I/O Controller Hub that may apply to the desktop board D845GVSR. 3 ® Intel Desktop Board D845GVSR Specification Update Summary Table of Changes The following table indicates the Specification Changes, Errata, Specification Clarifications, or Documentation Changes that apply to the desktop board D845GVSR. Intel intends to fix some of the errata in a future revision of the desktop board, and to account for the other outstanding issues through documentation or specification changes as noted. This table uses the following notations: CODES USED IN SUMMARY TABLE Doc: Document change or update that will be implemented. Plan Fix: This erratum may be fixed in a future revision of the desktop board, driver, or BIOS. Fixed: This erratum has been previously fixed. No Fix: There are no plans to fix this erratum. Shaded: This erratum is either new or modified from the previous version of the document. NO. PLANS ERRATA 1 Fixed PCI add-in video cards will not function as the primary video adapter 2 Fixed PCI video add-in cards will not display video when used as a stand alone video solution NO. PLANS SPECIFICATION CLARIFICATIONS 1 Doc Clarification of SMBus routing NO. PLAN DOCUMENTATION CHANGES 1 Doc Change to description of Table 53, Section 4.4.3, BIOS Setup program 4 ® Intel Desktop Board D845GVSR Specification Update ERRATA 1. PCI Add-In Video Cards Will Not Function as the Primary Video Adapter PROBLEM: If PCI is chosen as the primary video adapter option in the Advanced/Video Configuration submenu of BIOS Setup, the video adapter will not function. IMPLICATION: Users that desire to have either PCI only video adapters or have multiple video adapters such as a PCI video adapter in conjunction with the onboard AGP video, cannot set the PCI adapter as the primary video adapter in BIOS setup. WORKAROUND: Ensure that the Primary Video Adapter is set to “Integrated” in BIOS setup. STATUS: This issue was fixed in BIOS revision VA84510A.86A.0023.P08. 2. PCI Video Add-in Cards Will Not Display Video When Used as a Stand Alone Video Solution PROBLEM: If an add-in PCI video card is used without an AGP video adapter and PCI is selected as primary video in the BIOS configuration menu, no video will be displayed. IMPLICATION: Users who intend to utilize a PCI add-in video card as the sole device will not have video capability. WORKAROUND: None. STATUS: This issue was fixed in BIOS revision VA84510A.86A.0023.P08. 5 ® Intel Desktop Board D845GVSR Specification Update SPECIFICATION CLARIFICATIONS The Specification Clarifications listed in this section apply to the Desktop Board D845PESV Technical Product Specification (Order Number C46811). All Specification Clarifications will be incorporated into a future version of that specification. 1. Clarification of SMBus Routing Section 2.8.2.1 will change in its entirety as follows: 2.8.2.1 Expansion Slots The Desktop Board has three PCI rev 2.2 compliant local bus slots. The SMBus is routed to PCI bus connector 2. NOTE ✏ The SMBus routing to the PCI bus connectors does not conform to the PCI Engineering Change Notice (ECN) “Addition of the SMBus to the PCI Connector ECN”, dated October 5th, 2000. The ECN specifies that SMBus signals must be routed to all PCI bus connectors. On this board, SMBus signals are routed to PCI bus connector 2 only. Add-in cards that implement PCI bus connector pins A40 and A41 for any purpose other than SMBCLK (SMBus clock) and SMBDAT (SMBus data) should not be installed in PCI bus connector 2. For information about Refer to Addition of the SMBus to the PCI Connector ECN http://www.pcisig.com/data/s pecifications/smb_ecn_0405 01.pdf NOTE ✏ This document references back-panel slot numbering with respect to processor location on the Desktop Board. PCI slots are identified as PCI slot #x, starting with the slot closest to the processor. The ATX/microATX specifications identify expansion slot locations with respect to the far edge of a full-sized ATX chassis. The ATX specification and the Desktop Board’s silkscreen are opposite and could cause confusion. The ATX numbering convention is made without respect to slot type, but refers to an actual slot location on a chassis. Figure 6 on page 53 illustrates the Desktop Board’s PCI slot numbering. 6 ® Intel Desktop Board D845GVSR Specification Update DOCUMENTATION CHANGES ® The Documentation Changes listed in this section apply to the Intel Desktop Board D845GVSR Technical Product Specification (Order Number C46811). All Documentation Changes will be incorporated into a future version of that specification. 1. Change to Description of Table 53, Section 4.4.3, BIOS Setup Program.
