PREFACE
This document is an update to the specifications contained in the IntelDesktop Board D845GLVA Technical
Product Specification (Order number C30525). It is intended for hardware system manufacturers and
software developers of applications, operating systems, or tools. It will contain Specification 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 D845GLVA.
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
845 Chipset: 82845 Memory Controller Hub (MCH) for SDR Specification Update (Order
Number 298589) for specification updates concerning the 82845GL MCH Controller and that may apply to the
desktop board D845GLVA. 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

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 D845GLVA’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.

ERRATA
1. Some UDMA 6 Hard Disk Drives May Not Operate Properly
PROBLEM:Some ATA-133 (UDMA 6)hard disk drives may not be properly recognized by the system BIOS
to set the proper drive setting for ATA-100 (UDMA 5) operation that is supported by the IntelD845GEBV2
desktop board.
IMPLICATION:If the ATA-133 hard disk drive is not properly set to UDMA 5 in the BIOS Setup/Advanced/IDE
Configuration submenu, the user may experience failed operating system installation or other data corruption
issues.
WORKAROUND:In the BIOS Setup/Advanced/IDE Configuration sub menu, the UDMA setting can be
manually changed to UDMA 5.
STATUS:This issue was fixed in BIOS revision VA84510A.86A.0023.P08.
2. 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.
3. 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.

SPECIFICATION CLARIFICATIONS
The Specification Clarifications listed in this section apply to the Desktop Board D845GLVA Technical
Product Specification (Order Number C30525). 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.

# INTEGRATOR’S 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.
