M571 Motherboard sites

Getting support from PcChips, especially when downloading files, can be challenging. Many times, international internet connections are slow and unreliable, although it seems that access may vary by ISP. Sometimes it is necessary to try several times before these sites can be accessed or before drivers can be downloaded. For the large ones, plan on leaving the connection up at night. Here are several official PcChips sites:

PcChips Hong Kong
PcChips Taiwan - M571 Page Driver page
PcChips UK
Amptron Website - Many drivers, including Linux. Use the "support" selection
Alton Website -

M571 Component sites & technical documentation

Most of the credit for these links belongs to Franc Zabkar. His most valuable information is now available on this site:


I am also thankful to Brad of the EYO Tech Forum for his great help and valuable technical observations in assembling this page.

The urls of these files are posted to assist those who require further information regarding the operation of their M571 board components.

Many of these links change and I do the best I can to update them. Some of these liinks are no longer accessable through the main pages of these companies. It is strongly suggested that, if you have an interest in the M571 beyond that of the casual user, you download these files to your own system for future reference. Socket 7 motherboards are no longer "cutting edge", and there is no telling when these companies will see fit to remove older files from their servers.

AMD - K6 2 and K6 III processor descriptions (click here)

AMI - BIOS supplier

CET (Chino-Excel Technology) - Vcore power supply CEB703AL MOSFET chopper


Integrated Technology Express - IT8770F I/O Chip (same as IT8661 but w/o RTC and KBC) (click here)

Linear Technology - LT1083 CP adjustable linear I/O voltage regulator (click here)

NIKO - P804008 adjustable linear I/O voltage regulator

Phillips Semiconductors

Photron Semiconductor Corp. - PSR10C40CT Vcore power supply diode

Samsung/Fairchild - KA7500B Vcore power supply PWM Regulator (click here)

SiS - 5597/5598 chipset - self expanding Wordpad .DOC file. This link is no longer listed on the SiS site, but it is available here. Download this file now, while it is still posted, since it is key to tweaking chipset registers (click here)

Texas Instruments - GD75232 RS232 Line Driver/Reciever Chip (click here)

Utron Technology


Due to the increasing age of M571 3.2, 3.2a, and 7.0 systems, it is suggested that you download the drivers you need and think you may need and store them for future use.

C-Media 8330 Sound Pro (click here) The 2.0 version drivers are beta.

SiS 5597/5598 IDE drivers - These drivers can be downloaded from the SiS site, but I'm not posting the url here. If you are using Win 95 OSR2 or better, you don't need the SiS IDE 2.13 version driver. (I stress this because it has caused trouble for people in the past.) If you load it, you will have to remove the controller in the device manager and let Windows find it again and use Windows busmastering IDE driver. The SiS dirver will not provide a DMA box to check, whereas the standard Windows driver will. For the majority of M571 users, you don't need the SiS IDE driver. See question #4: (click here)

SiS 5597/5598 VGA drivers (click here)

SiS IDE drivers for Windows 2000; allows activation of DMA (IDE 2.02)

Franc Zabkar's M571 Tech Files - Franc has assembled an incredible treasure trove of M571 technical information in these text files. These files were some of the first technical help for the M571, back in the days when technical support was hard to find for this motherboard. Many M571 circuits have been analyzed and presented here. Since Franc has removed these files from his website, he has graciously consented to having them posted here, for your use. Thanks, Franc!
