So I just installed a 486 with heatsink and fan into my HP Vectra 486/66n. The DX2 66 was working fine, just wanted an upgrade.
Well the bios detects it as a DX4-100. But when booting ms-dos it locks up right after trying to load QEMM. So I reboot and hit F5 to bypass config.sys, and it works, but as soon as I try to list a directory or run edit or anything it crashes.
Seems like the CPU is bad? Anything else I can do to verify that?
