The BIOS ID string does match Intel Triton FX and Epox. Being a Rev 0.2 seems very odd, usually they start with Rev 1.0...but saw a few Epox with it, an IT and a ET with same rev #
so think your thought on Epox is correct. Went thru my EPox archives and found some stuff, one link listed this: http://web.archive.org/web/19970410145646/htt … x.com/bios.html (the TW site has nothing that oild I could find)
shows 3 diff P55-IT variants. The bios for the SMC has this ID: Award.01/13/96-i430FX-2A59CPAIC-00 and is same BIOS as: https://theretroweb.com/motherboards/s/epox-pronix-ep-p55-et
also found the 8/1995 bios for P55-IT with this string: Award.08/04/95-TRITON-2A59CPA9C-00 which matches yours
Too bad you have a soldered eprom, if it were socketed be easy with a TL866 to save current and flash with the newer one and test, then if not working reflash back.
fwiw: The BCC stickers are most likely some small computer shops part numbers (like Bertha's Custom Computers # 🤣).
attached all the P55-IT various bios found and html from archive with description...

Thanks @Horun! After more digging I discovered this is the Epox EP-P54C-IP board and have submitted the info to TheRetroWeb. I'm going to try to dump the flash and flash something newer, as it's having a hard time detecting any drives I throw at it. You're right about the BCC stickers, it's from the Business Computer Center haha.

Hi nickpunt,

I’ve found ‘something newer’ to flash for your Epox P54C-IP board! 😉
It is a 03/16/2000-i430FX-2A59CPA9C-00 BIOS update for your board from Unicore Software that comes with the Evergreen Spectra K6-2/400 upgrade CPU package. This 03/16/2000 BIOS does not only break the 8GB barrier but also fixes the 32GB and 64GB HDD limit bugs for full 128GiB HDD support!
In addition, it supports all socket 7 CPUs from Intel, AMD, Cyrix, Winchip, and Rise. So also the K6-2+/K6-III+ are supported.

Cheers, Jan

Great ! Did not even think of looking in the Evergreen utils for an update.

Hi Horun,

Yes, that Evergreen Spectra Utilities CD v4.0 is a real treasure trove of early socket 7 BIOS upgrades!
It was great that 2 years ago user RichardG867 was able to decode this CD-ROM and made these about 3600 BIOSes available for download at https://archive.org/details/evergreenspectrabios 😀

Only recently I became aware of this great resource, thanks to one of vswitchzero’s excellent videos, the one about the Evergreen Spectra 400 upgrade CPU:

I just saw a message from evasive about the huge task of incorporating all these BIOSes in TheRetroWeb database. I hope you guys can pull this off and have these BIOSes on TRW in the near future. 😀

Wow thank you so much Jan! I'll give this a shot when I crack open the old ratrod again 😀
