Thanks! Its now setup for a Duke3d LAN party for this weekend.

YES!! Thanks to everyone! It was the FP RAM vs EDO. By the way, either BIOS works, both Award and AMI!!

Correct pinout/pincount was selected this time. I tried both AMI and AWARD from the link above on Archive.org. (Thank you!) Here are the results of each - still no workie: https://youtube.com/shorts/btv0UOck9Co?feature=share <--AMI https://youtube.com/shorts/_2m9VQgdhLk?feature=share <--AWARD

Tried switching to plain W29EE011 - no luck. The 13 10 is when using AMI. When using Award it gives the same screenshot I put up that shows 'BIOS ROM checksum error', then 1 short 1 long beep. Code: 41 0d

Updated my TL866 software and firmware. Tried 2 different Winbond EEPROMs. Both show no errors. Does it look like my settings are correct? Getting Code 13 10 on the post analyzer with no video.

Greetings - I have 2 of these identical boards that came with NO BIOS Chips. Using a WinBond W29EE011-15 I was able to program each of these BIOS files with my TL866 and the only ones that have some type of result are the AWARD files. (See pic from output). https://theretroweb.com/motherboards/s/msi …

Does anyone know how I can identify this chip? I found another thread which talks about how to get Device ID and that showed C2 1A. It's an AMIBIOS from a PCChips M530 motherboard. https://theretroweb.com/motherboards/s/pcchip … -m530#downloads
