Ok, don't laugh, but I just got my old 486 running, and it's not that bad, but I need to update the Bios for this board: (Alaris Cougar 486BL Motherboard) It's from about 1993. I've looked around but can't find anything. So anyone out there PLEASE help me out. It would be so cool to get this system running 100% <IMG SRC="smilies/tongue.gif" border="0">
hate to say this but i don`t think that you can flash the bios for this old boardthe only way i know to do it is to use an eeprom burner and change what`s in the bios yourself,or maybe buy a new bios for it,good luck, clauded
Have to agree with Clauded...only few 486 old motherboards I have ever seen had flash IC as BIOS (mostly from ASUS or another well-known manufacturer). Look at top cover of BIOS chip. If there is small transparent window (covered by BIOS logo sticker),- it definately isn't flash IC... It's Ultra-Violet erasable chip, what can be erased using special lamp, and then programmed using stand-alone programmer.Quote:

For that age of motherboard, you might be able to get a BIOS chip from Unicore software (might be a little pricey, DON"T let them talk you into any software) or an ISA BIOS update card (I have one of these laying around extra). The Bios card might take a little searching to find, all present BIOS's are more than Y2K compliant.
I'd offer to send you the extra card I have, but sending it from Michigan to Canada might be a little sticky. If you know different, the offer is open.
Hope this helps. <IMG SRC="smilies/smile.gif" border="0">
