M571 Notes Updated 2011/03/13
Even More M571 information from here. Notes: Video Chipset as None is incorrect. It is SiS 5598.
Chipset Aliases: TX Pro, VX Pro and Co. - Interesting article on the chipset aliases, including the TX Pro II.
[Very old] EYO Tech Forum FAQ - Old technical info about the M571 regarding BIOS bugs, undocumented jumper settings, hardware modification. Mainly about the V7.0 board. Pulled from a year 2000 Wayback Machine archive entry.
M571 V3.2 Voltage Hack, ZIP File - Hardware voltage modification for the PCChips M571 V3.2 (NOT V3.2A) motherboard.
M571LMR Voltage Hack, ZIP File - Hardware voltage modification for the PCChips M571LMR motherboard. Original document warns of it not being tested properly and may have errors.
Drivers:
PC Chips Drivers CD Ver. 3.0 - Even older set of drivers that came with the motherboard.
PC Chips Drivers CD Ver. 3.5 - Older set of drivers that came with the motherboard.
PC Chips Drivers CD Ver. 3.6 - Last known set of drivers that came with the motherboard.
PC Chips Drivers CD Ver. 3.9 - Another set of drivers that came with another motherboard. Otherwise, the same as v3.6, but with updated PCI SoundPro sound drivers. The BIOS Flash utilities were updated as well.
All are from here and here. Site is down as of 2011/02/25. Scary, as I downloaded these three weeks ago. I'm glad I did not hesitate to get these... because the site isn't archived, either. O.O Site now exists again, but nothing else is there. 2011/03/22 Link now changed from kandk4u to Embrace Computers because it redirects there. The directory structure hasn't changed either; that's how I knew it was one and the same. 2011/06/02

BIOS:
v1.3, v3.2/v3.2A, v7.0 - M571
v1.1, v3.0, v5.1 - M571LMR
Notes for the M571LMR:
Any v5.1 BIOS starting with October 2000 (though BIOS release notes state March 9, 2000!) is stated to work with all revisions of the board. Only thing is the BIOS chip size difference on the board.
All v1.x revisions are 2M (256K) releases.

Manual:
Original PCChips Manual, Updated Version - Manual originally linked on Timmy's site. The true original has encoding issues, so this is the best version available.
Amptron PM9100 Manual - Manual of the Amptron version of the M571. Grabbed from a very old archive of the Amptron website, courtesy of Archive.org's Wayback Machine.
Reference:
Old PCChips BIOS Download Page - Old BIOS page of where the early BIOS files were linked in 1999. Unfortunately (and not surprisingly), all of the links to the BIOS files are dead. Also, note ONE little thing in that list... the 1999/03/05 BIOS is NOT listed there, but the 1999/04/21 BIOS is. Hmm...
