ESD Precautions

Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:

 Do not remove boards or integrated circuits from their anti-static

packaging until you are ready to install them.

 Before handling a board or integrated circuit, touch an unpainted

portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.

 Wear a wrist-grounding strap, available from most electronic

component stores, when handling boards and components.

5.1 Introduction

5.1 Graphic Controller

The 852GM provides a highly integrated graphics accelerator
delivering high performance 2D, 3D, and video capabilities. With its
interfaces to UMA using a DVMT configuration, an analog display
(CRT port), a LVDS port for digital LCD connection and optional
second LVDS LCD interface (via Chrontel CH7305 converter on
AX93200), the 852GM can provide a complete graphics solution. The
852GM also provides 2D hardware acceleration for block transfers of
data (BLTs). Performing these common tasks in hardware reduces
CPU load, and thus improves performance. High bandwidth access to
data is provided through the system memory interface. The 852GM
uses Tiling architecture to increase system memory efficiency and
thus maximize effective rendering bandwidth. The Intel 852GM
GMCH improves 3D performance and quality with 3D Zone rendering
technology. The Intel 852GM GMCH also supports Video Mixer
rendering and Bi-Cubic filtering.

5.2 Features

z The STX88810 adapts Intel 852GM GMCH provides three

display ports, one analog and two digital. With these interfaces,
the GMCH can support for a progressive scan analog monitor, a
dedicated single/dual channel LVDS LCD panel and a converted
LVDS LCD interface through DVO channel. Each port can
transmit data according to one or more protocols. The data that
is sent out the display port is selected from one of the two
possible sources, Pipe A or Pipe B.

z Intel 852GM GMCH has an integrated 350-MHz, 24-bit

RAMDAC that can directly drive a progressive scan analog
monitor pixel resolution up to 2048 x 1536 at 75-Hz refresh. The
Analog display port can be driven by Pipe A or Pipe B.

Display Drivers

27

STX88810 STX Evaluation Platform Module Series User’s Manual

z The Intel 852GM GMCH has an integrated dual channel LFP

Transmitter interface to support LVDS LCD panel resolutions up
to UXGA. The display pipe provides panel up-scaling to fit a
smaller source image onto a specific native panel size, as well
as provides panning and centering support. The LVDS port is
only supported on Pipe B. The LVDS port can only be driven by
Pipe B, either independently or simultaneously with the Analog
Display port. Spread Spectrum Clocking is supported: center
and down spread support of 0.5%, 1%, and 2.5% utilizing an
external SSC clock.

Award BIOS Utility

The different settings are available in the Award BIOS and along with

the STX88810 board. Also contained here are instructions on how to

set up the BIOS configuration.

7.1 BIOS Introduction

The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel Celeron processors in a
standard IBM-AT compatible I/O system. The BIOS provides critical
low-level support for standard devices such as disk drives, serial and
parallel ports. It also adds virus and password protection as well as
special support for detailed fine-tuning of the chipset controlling the
entire system.

7.2 BIOS Setup

The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system
stores the Setup utility. When you turn ON the computer, the Award
BIOS is immediately activated. Pressing the <Del> key immediately
allows you to enter the Setup utility. If you are a little bit late pressing
the <Del> key, POST (Power On Self Test) will continue with its test
routines, thus preventing you from invoking the Setup. If you still wish
to enter Setup, restart the system by pressing the ”Reset” button or
simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys. You
can also restart by turning the system OFF and back ON again. The
following message will appear on the screen:

In general, you press the arrow keys to highlight items, <Enter> to
select, the <PgUp> and <PgDn> keys to change entries, <F1> for
help and <Esc> to quit.

When you enter the Setup utility, the Main Menu screen will appear
on the screen. The Main Menu allows you to select from various setup
functions and exit choices.

NOTE:

If you find that your computer cannot boot after making
and saving system changes with Setup, the Award BIOS,
via its built-in override feature, resets your system to the
CMOS default settings.

We strongly recommend that you avoid making any changes to the
chipset defaults. These defaults have been carefully chosen by both
Award and your system manufacturer to provide the absolute
maximum performance and reliability.

Ultra DMA/66/100 Reference

Overview

Ultra ATA66/100 is a low cost extension of the Ultra ATA/66/100 hard
drive interface that enhance its burst data rate. Also known as Ultra
DMA/100 and Fast ATA-2, Ultra ATA/66/100 allows host computers to
send and receive data at 100 MB/s, which is triple the data transfer
speeds of 33.3 MB/s of Ultra DMA/33. The result is maximum disk
performance under PCI local bus environments.

At its fast burst data rates, Ultra ATA66/100 will go farther than Ultra
ATA66/100 in removing bottlenecks associated with data transfers,
especially during sequential operations. Ultra ATA66/100 also delivers
heightened data integrity to the EIDE interface through use of a 40-pin
80-conductor cable, and CRC (Cyclic Redundancy Check) error
detection code. The 80-conductor cable reduces crosstalk and
improves signal integrity by providing 40 additional ground lines
between the 40-pin IDE signal and ground lines. The connector is plug­compatible with existing 40-pin headers, and the incremental cost for
the cable should be minimal. As with Ultra ATA/33, CRC ensures the
integrity of transferred data.

Ultra DMA/66/100 Reference

63

STX88810 STX Evaluation Platform Module Series User’s Manual

Background

Ultra ATA/100 is the latest ATA/IDE hard drive data transfer protocol
for moving data between the hard drive buffer and the system memory.
The previous interface was Ultra ATA/66, with a maximum burst
transfer rate of 66.6 MB/s. Prior to Ultra ATA/66 was Ultra ATA/33 with
a maximum burst transfer rate of 33.3 MB/s.

By increasing the burst transfer rates of IDE drives, Ultra ATA/100
brings the effective transfer rate of the system’s bus and a drive’s
internal data rate that much closer into balance. Ultra ATA/100 allows
system designers to provide greater system throughput, particularly for
long sequential transfers required by audio/visual applications.

Host data transfer rates must exceed media data transfer rates or else
performance is reduced because of additional revolutions due to buffer
full/empty conditions on reads/writes.

Host Data Rate Requirements

As you can see by the chart, the host data transfer rate doubles about
every three years. The chart indicates that Ultra ATA/100 will reach its
limits by 2000. The industry has supported host transfer data rates
doubling previously with:

z DMA Mode 2 at 16.6 MB/s in 1994
z Ultra ATA/33 at 33.3 MB/s in 1997
z Ultra ATA/66 at 66.6 MB/s in 1999
z Ultra ATA/100 at 100MB/s in 2000

With continued expansions in disk capacity and higher rotational
speeds, the hard drive’s internal disk rates also continue to increase.
The transfer of large files, often written sequentially on the hard drive,
is particularly affected by the transfer rate. During sequential reads, the
hard drive, because of its fast internal data rate, may fill its buffer faster
than the host can empty it when using the Ultra ATA/66 or the older
multi-word DMA interfaces. Performance bottlenecks usually result in
this connection between the host and the hard drive. Improving the
interface to keep up with internal data rate improvements is exactly
what Ultra ATA/100 can achieve.

As previously mentioned, fast host data transfer rates help maintain
sequential media transfers, but they also accelerate cache hits. The

64

Ultra DMA/66/100 Reference

STX88810 STX Evaluation Platform Module Series User’s Manual

following table is based on all commands are either a cache hit (data
comes from the buffer and has <1 ms latency), or a cache miss (data
comes from the media and has >10 ms latency.)

Ultra ATA/66 Performance Benefit

Cache Miss Cache Hit

Sequential Yes Yes
Random No Yes

Backward Compatibility

The Ultra ATA/100 protocol and commands are designed to be
compatible with existing ATA devices and systems. Drives
implementing Ultra ATA/100 are fully backward compatible with older
ATA modes, including Ultra ATA/33/66. It will handle all the data
transfer modes. The slower modes will be supported with a different
clock signal and clock divider. The slower modes previously worked
with a standard 40-pin interface cable, but Ultra ATA/66/100 requires a
40-pin 80-conductor cable for modes 3 and 4.

STX88810 STX Evaluation Platform Module Series User’s Manual

Hard drives that support Ultra ATA/66/100 also support Ultra ATA/33
and multi-word DMA, and can be used with existing multi-word DMA
host chipsets. Installed PCs without Ultra ATA/100 capability can use
new hard drives in legacy ATA modes at transfer rates up to 33.3 MB/s.
However, by upgrading with an Ultra ATA/100 PCI adapter card and
80-conductor cable, they can also take advantage of the interface’s
newer speed and data integrity features. Bus timings must be scaled to
transfer up to twice as fast. PC vendors who would like to incorporate
the advantages of Ultra ATA/100 in new systems can do so by using
new chipsets and motherboards from Intel and other leading vendors
that license the technology. Although a new cable is required for Ultra
ATA/66/100, the chipset pin count remains the same at 40.

System Requirements for Ultra ATA/66

To use the Ultra ATA/66/100 technology, a system must have:

z Ultra ATA/66/100 compatible logic either on the system

motherboard, or on an Ultra DMA PCI adapter card

z Ultra DMA compatible BIOS
z DMA-aware device driver for the operating system
z Ultra ATA/66/100-compatible IDE device such as a hard

drive or CD-ROM drive

z 40-pin 80-conductor cable

Frequently Asked Questions

1. Can I run UDMA/66/100 on a 40 pin 40 conductor cable?

No, the UDMA/66/100 technology is defined such that the PC and

the HDD can both detect the presence of the 80-conductor cable.

UDMA/66/100 will not be enabled unless the 80-conductor cable

is present.

2. I have an UDMA/33 system today. How can I support UDMA/66/100?

An existing system can be upgraded by purchasing a PCI-EIDE

controller that supports UDMA/66/100.

3. Do Microsoft Operating Systems support UDMA?

Windows releases indicate that they all support DMA
transfers. Windows does not know the difference between
Ultra ATA/33 or Ultra ATA/66/100. Your HDD, your
controller and the BIOS determine UDMA data transfer rate.
This applies for all the following Windows operating
systems:

- Windows 98

- Windows NT Service Pack 3

- Windows 95 OEM Service Release 2

4. I don't have a system that supports Ultra ATA/66/100, can I run the

Ultra ATA/66/100 HDD in it?

Yes, the HDD will not run in UDMA/66/100 mode but instead is a

slower compatible mode such as Ultra ATA/33, DMA Mode 2 (16.6

MB/s) or PIO Mode 4 (16.6MB/s)

5. Can I mix Ultra ATA/33 and Ultra ATA/66/100 drives on the same

cable?

Yes, a legacy ATA (IDE) specification drive can coexist with an Ultra
ATA/66/100 drive. However, for the Ultra ATA/66/100 device to attain
Ultra DMA 4 mode, an Ultra ATA/66/100 capable cable is required.

6. What are some common troubleshooting steps?

- Make sure the cable is Ultra ATA/66/100 capable. An Ultra ATA/66/100-capable

cable is a 40-pin, 80-conductor cable with a black connector on one end, a blue
connector on the other end and a gray connector in the middle. In addition, line 34
on the cable should be notched or cut (this may be difficult to see with the human
eye).

- Make sure the system board is capable of Ultra ATA/66/100. An Ultra ATA/66/100

capable system board has a detect circuit with a capacitor for detecting line 34
missing on the cable. If there is no capacitor, the system can wrongly detect the
presence of an Ultra ATA/66/100 cable and therefore try to configure the device
for a higher transfer rate.

- Some system boards may not successfully handle Ultra ATA/66/100 on both ATA

(IDE) channels. If you have difficulty, consider troubleshooting with the device in
the Primary Master position.

- Contact the system board manufacturer for the latest BIOS upgrade and any Ultra

ATA/66/100 special device drivers or patches.

- Make sure the operating system is DMA capable and that the DMA mode is

activated. (For Windows 95/98, check Device Manager | Drive Settings tab for a
check box.)

- Make sure the drive is Ultra ATA/66/100 capable and has been configured to run

at Ultra ATA/66/100 transfer rates. (Seagate drives require an Ultra ATA/66/100
activation utility.)
