Motherboard Manufacturer ?

Recommended by Wim's BIOS...

I have not been able to find the Manufacturer of my Intel chipset m/board.
Bios ID on bottom of screen reads:
03/15/1999-i440ZX-W977EF-2A69KPWBC-00
Could you please help, Manufacturer code is PW & not on your current list :
I have been on chaintechs' site, some files d/loaded but no luck. Intel replied but cant shine any light on manufacturer.
Thanks to ajzchips for reply, and all that looked in on my submission.

Found the manufacturer, but no responses to date. Protac Taiwan (Chaintech). Have all drivers, but need manual to isolate CD Sound failure, even though Windows sounds work. Keep hoping.

Still trying to find Mobo resources for this board. Can't someone help?

Send me a copy of your bios and I try to patch it.
