PREFACE
This document is an update to the specifications contained in the Intel®Desktop Board
D102GGC2 Technical Product Specification (Order number D44278). 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 D102GGC2. 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 ATI website for product advisories for specification updates concerning the Radeon
Xpress 200 that may apply to the desktop board D101GGC2 . Unless otherwise noted in this
document, it should be assumed that any northbridge or southbridge 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
D102GGC2’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.

SPECIFICATION CHANGES
The Specification Changes listed in this section apply to the Intel®Desktop Board D102GGC2
Technical Product Specification (Order Number D44278). All Specification Changes will be
incorporated into a future version of that specification.
1. Change to Section 1.5.4.1, Parallel ATA IDE Interface
Section 1.5.4.1, Parallel ATA IDE Interface will change in its entirety to remove support for ATA-
133 interface as follows:
1.5.4.1 Parallel ATE IDE Interface
The IXP 450’s Parallel ATA IDE controller has two bus-mastering Parallel ATA
IDE interfaces. The Parallel ATA IDE interfaces support the following modes:
•Programmed I/O (PIO): processor controls data transfer.
•8237-style DMA: DMA offloads the processor, supporting transfer rates of
up to 16 MB/sec.
•Ultra DMA: DMA protocol on IDE bus supporting host and target
throttling and transfer rates of up to 33 MB/sec.
•ATA-66: DMA protocol on IDE bus supporting host and target throttling
and transfer rates of up to 66 MB/sec.
•ATA-66 protocol is similar to Ultra DMA and is device driver compatible.
•ATA-100: DMA protocol on IDE bus allows host and target throttling.
•The IXP 450’s ATA-100 logic can achieve read transfer rates up to 100
MB/sec and write transfer rates up to 88 MB/sec.
 NOTE
ATA-66 and ATA-100are faster timings and require a specialized cable to reduce
reflections, noise, and inductive coupling.
The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM
drives) and ATA devices using the transfer modes.

The location of the Parallel ATA IDE connectors Figure 7, page 44

2. The following note will be added to the Technical
Product Specification in Section 2.7.1 Back Panel
Connectors:
 INTEGRATOR’S NOTES
Electrostatic discharge (ESD) can damage desktop board
components. Front-panel connectors should provide sufficient
protection to prevent ESD damage to components inside the
chassis enclosure.
3. Reference to support for second-generation SATA drives
is being removed. Section 3.3.2 PCI IDE Support will
change its entirety as follows:
3.3.2 PCI IDE Support
If you select Auto in the BIOS Setup program, the BIOS automatically sets
up the PCI IDE connector with independent I/O channel support. The IDE
interface supports hard drives up to ATA-66/100 and recognizes any ATAPI
compliant devices, including CD-ROM drives, tape drives, and Ultra DMA
drives. The interface also supports SATA drives. The BIOS determines the
capabilities of each drive and configures them to optimize capacity and
performance. To take advantage of the high capacities typically available
today, hard drives are automatically configured for Logical Block Addressing
(LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You
can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
To use ATA-66/100 features the following items are required:
•An ATA-66/100 peripheral device
•An ATA-66/100 compatible cable
•ATA-66/100 operating system device drivers
NOTE
Do not connect an ATA device as a slave on the same IDE cable
as an ATAPI master device. For example, do not connect an ATA
hard drive as a slave to an ATAPI CD-ROM drive.
