Can't Enter in to BIOS

[kashifns]

One of my friend gave his old PC to fix it up. That is Compaq Professional Workstation 5100. Whenever I boot it up I receive 162 System Options Not Set. I searched and found that we need to go in to BIOS and save the settings once again and it will work fine. But that computer is not letting me to get in to BIOS. I know I have to use F10 key for BIOS. Any idea what to do?

Just to Add up

Just to add up that I have tried Del, F1, F2, Shift+Esc and other key combinations to get in to BIOS. What I know about old Compaq systems are that they keep the Bios Program on Hard Drive and as this computer don't have native Compaq Hard Drive so it might be a problem.

Windows XP Professional with SP2 is working fine on this computer.

Are you using USB or PS/2 Keyboard?

At the moment PS/2. I can try with USB keyboard as well. Even keyboard is working, I am used to skip the memory check of 256 MB.
