I picked up an untested Socket 4 motherboard with many missing components, labeled Biostar MB-1566-PAT-A. After replacing the cache, memory, CPU, and keyboard BIOS, I was able to bring it partially back to life.
It came without the keyboard BIOS chip, so I pulled one from another motherboard I have. Thing is, all the socketed chips I have are this model:
Swapping in this keyboard BIOS, I am able to get the mobo to start. However, the keyboard is very unresponsive. On each boot, I'm only able to get one or two delayed keystrokes in before the keyboard quits. Probably because this model of keyboard BIOS is incompatible.
Since I don't have any other socketed keyboard BIOS chips to try, I'll have to buy a replacement. Does anyone here have experience transplanting these keyboard BIOS chips? Which brand might be worth a try— AMIKEY, JETKEY, VIA etc? Unfortunately I was unable to find reference photos of this exact mobo with the keyboard BIOS present. Thanks in advance.
