The problem is the device is not being recognized. You will at least need to try a USB keyboard to see. You can get a cheap $5 one at places such as Big Lots. It may not be a great keyboard but enough to test.
I've seen PS/2 keyboard ports go bad (the Keyboard I/O chip) and this could be what has happened.
Once you reset the BIOS there is some manual interaction required. I don't see flashing the BIOS as getting you anything, if you can even do it.
The ironic thing is that the PS/2 keyboard worked without issues before I reset CMOS. My actual problem was that the PS/2 mouse nor my USB mouse was working (which was my original troubleshoot) and on top of that I then couldn't get into BIOS to see the status. Now, the keyboard too......ughhh.
This is an old board (2007) and it has served me very well and I do want to build a 64bit system next, but I'll have to keep this one going until I can afford the other one.
Next stop....cheap $5 USB keyboard (Alegria, I appreciate you getting the link, but this will be quicker than waiting for it to be shipped).
Thank you very much for all your help, you guys are great and this is one of the reasons I enjoy being part of this community.
