bio's problems

I can't get in my bio's. How can i fix my problem? I wiped my hard drived and reinstalled xp's. and still have no boot up and still can't get into my bio's. Is there a short cut? (back door) F5 dont work F8 dont work F10 don't work. No system recovery. I need my CD to boot from. But it works fine from there. Can you help me out anyone?
:cry

 

Most BIOSes are accessed with F2, F1, or Del. If none of these work, post the make and model of your PC and/or motherboard, and we'll do our best. If you're using a USB keyboard, it could be that USB keyboard support is not enabled in the BIOS which would prevent a USB keyboard from working until Windows is loaded; buy or borrow a standard PS2 keyboard (they always have 'em at thrift stores for $5 or less). You can also open the case (unplug the main power cord first) and use the motherboard jumper to clear the BIOS. Then when the PC is powered on after clearing, you'll get a prompt saying that the BIOS vaules are incorrect (CMOS checksum error) and you'll be told to press this key to enter BIOS, press that key to install defaults, etc.....

I hope this helps! Keep us posted!
