Hi, I have an old AT motherboard that I’ve been trying to bring back to life for the heck of it. Although it hasn’t seen the light of day in awhile it does come on and post but the keyboard isn’t recognized and the ps/2 connection doesn’t seem to be working either. Also it shows the hard drive and cd as primary slave when the are set to cable select and plugged into the master end of the cable. The usb connections are working and a usb keyboard will work but it won’t work if I try to install an OS. I thought it was a corrupt bios so I flashed the bios with an updated version I had found for this board and no difference. Its a Lucky Star 5V3P ver 2.1 Socket 7 with AGP with 128mb ram and AMD K2 300mhz cpu. It has a 5 pin DIN keyboard connection and a header to connect a ps/2 adapter. I have tried other keyboards and I use a ps2 to 5 pin adapter. Tried it on another old mobo and no problems. If anybody has any ideas or solutions, let me know. Just a shot in the dark!
