Reseted Cmos and the motherboard don't recognize the keyboard

[tedyy]

I found some old motherboards in a box some days ago and I started to try them.
One of them (maxtone 94v-0 socket 370 sdram) after installing 2 sticks of ram , a cpu,mouse , keyboard , and a HDD the computer started and showed me the post message and after an error message saying that I do not have a floppy installed and that I reseted the cmos and I have to press either F1 to run the setup or F2 to load the default values.
The problem is that the keyboard is not recognised and I can't press anything. I even tryed an usb keyboard and the same thing happened.
what could I do?

An old socket 370 motherboard may not recognize a usb keyboard. You may need to use a PS2 keyboard until you can get into the BIOS and change the settings to recognize legacy devices. Even then, depending on the hardware support of that device, it might just require a ps2 mouse and keyboard until it boots to the point where windows drivers take over.

The first time I used a PS2 mouse and Keyboard but nothing happend when I pressed F1 or F2 or delete, and I used the same keyboard on other motherboards the same and everything was ok. The second time I used a USB one and the same thing happend.
Right now I do not know what to do. I know that If I resolve this problem this motherboard will work properly

Perhaps the problem with the motherboard is the I/O circuit for the keyboard. Maybe it's why the board got retired in the first place. You might even try another PS2 keyboard. Check the socket holes in the PS2 connector on the board to make sure there is no dust or dirt or cobwebs that sort of thing in there. Blow it out a bit. Old electronics do tend to get some corrosion when sitting, especially in damp storage areas. If none of the above helps, try to reset the cmos, not with the battery, but with the jumper pin. Some systems would not revert to default settings just by removing the battery. Also, try replacing the battery with another known good one. Lastly, it might just be like I said earlier and the ps2 input is bad.
