Every computer needs a keyboard at the moment of boot time. Whether you are just bypassing BIOS or entering BIOS Setup, you need a keyboard to enter or change the value of the SETUP. In this case, no matter how skilled you are, you can't do anything without a keyboard.
This post idea came from the situation when I tried to build up a desktop PC with MSI mainboard, given by my cousin. He gave me the old Pentium 4 mainboard, and also given me the RAM and VGA cards. So after building it, I found that the keyboard just won't work. I tried with PS/2 and USB keyboard, and it just won't work. Then I called a technician who gave a solution which probably worked.
The solution is: turn off the PC and then remove the CMOS battery. Wait for quite a while around 30 minutes, then installed the battery again and turn on the PC. He said that this usually works well.
But unfortunately, it still didn't work for me. I brought it to another technician who was said to be expert in fixing mainboard.

Clearing CMOS settings
There are a few ways to clear CMOS settings. Actually, when your mainboard CMOS battery has begun to run out, your CMOS settings would probably getting closer to default. There's one common reason why we need to clear the CMOS settings, that is: when we want to make adjustment to the CMOS settings, but it's password protected. Clearing the CMOS also means that clearing the password.
To clear the CMOS settings, we can use one of the following methods, depending on the mainboard type. Usually for older mainboard, we can just remove the battery and turn the computer on for a while and then reinstate the battery. This is quite easy.
But if you can't remove the battery (which is probably soldered on the mainboard), look for a Clear CMOS jumper. Change the jumper position. To do this, you'd better follow your mainboard manual. If you don't have, don't worry to have experiment on it. But make sure that the jumper you are making experiment with is the Clear CMOS jumper.
Some branded computers make it easier for technician to clear the settings. Try looking
for a push on/off switch. If you can see the switch, you can just push it and then the settings are automatically reset.
The tips above are suitable when you can't access through the boot process, because of the password requirement on booting. But if you can boot, but cannot enter the CMOS, you can still use an easier way to remove the CMOS settings, that's by using freeware to clear it. Here's a link to the freeware:
