Ok I'm looking for a bios image for this old board.
8-30 pin simm slots.
486DX-33, this board has a crystal-in-a-can on it not a PLL (66MHz).
The CPU slot is a mega-tonne (lots) insertion force socket, and has the 487 co-pro socket.
Symphony chipset: SL82C461, SL82C362, SL82C465.
Keyboard bios is: OPTI80C42 (copyright by MR Bios)
Good ol Dallas Real Time clock/cmos: DS1287.
8-28pin Cache DIPs and a TAG.
The original bios was an AMI. Someone thought it would be funny to put it in backwards. If you know Bios' you know what this means.
There is a sticker but I'm sure it won't help: ASI266418.
I thought it was ASI Inc. but no joy.
There is acouple ways you can help me. Locate the right bios for it or where can I get AMI, Phoenix or Award bios' for a eprom 27c512. (This would mean alot of them.. or just some). Or I guess you could email me a dump of an older 486 bios, if you can throw your old board together to get it.
Thanks for your help..
Oh and yes it's possible to get the wrong bios to work.
