usb keyboard will not work before boot [solved]

I have a usb keyboard, it's not working before boot on my system. I am aware that some BIOS disable usb to speed boot along and that the common way to fix this is to use a ps/2 keyboard however, I just drove 35 miles round trip to find a store which carried a usb->ps/2 keyboard adapter, and when it's plugged into the ps/2 keyboard port it will not work at ALL, even after boot. After windows starts, the kb works fine if it's plugged into usb.

A friend of mine suggested holding down the power button, saying that some will let out three short beeps and this will clear it and USB will load before boot but all this did was cycle the power on and off again.

I cannot get into BIOS to change the setting.

Looking at the back of the PC, plug the keyboard into the top left USB port.

Some motherboards give priority to that slot.

thank you, but I solved the issue by taking out my CMOS battery to reset the BIOS.

The the post is right above, the keyboard has to be plugged into the right usb port to get into the bios in some cases.

Once in the bios you want to be looking for and option in there that says
USB legacy devices, make sure it is enabled.

Save the settings in the bios, and exit.
After that any usb port the key board is connected to should allow you to use the keys, to access the bios or windows menu`s when booting if pressed.
