Ok here's the story, I have an old PC-Chips (M-571) motherboard (no I didn't buy it) which was running a cyrix MII 300, so I bought a k62 500 for it to run at x6.0 (2.0) by 83mhz bus. When I popped the chip in it posted at 500 mhz as an AMD k6 (tm) -2 500. But as soon as it tried to read a boot drive it beeped at me and froze. So I spent the next half hour online, found what I thought was the latest bios and flashed it, pluged the k62 back in, and the thing did it again, so I went back online and found a bios version from early this year that somehow I had missed. So I went to install this newer bios and everything goes fine up until the point when it should start flashing it, and the flash program (AMIFL818.exe & AMIFL817.exe) tells me that the bios file is to large (256k). Has anyone experienced this before? I tried the pervious version of it (AMI817.exe) but I couldn't find an earlier version. If anyone has any suggestions or has AMIFL815 laying around any help would be greatly appreciated. Thanks in advance.
