Not sure if this will help but I think I remember doing something like this when I installed my new motherboard. Have you tried changing the boot order for which the computer boots, to boot from the motherboard CD to access its menus? Usually, on the very first screen when you turn on your computer, you will see some keys at the bottom of the screen for different menus. There should be one for setup that is usually accessed by pressing DEL, F8 or F12. You will have to see what your screen says to see exactly what key it is, as computers are all different. There should be a "Boot" tab on the next screen that you have to use your arrow keys to get to and hitting Enter to select it. You will see a list of items on the left. The list is the order in which your computer boots up it's programs. Change it so the CD-ROM boots first. This will boot the CD in which you should be able to get access to the CD menu. Insert your CD and restart the PC. On the CD menu see if you can maybe find something that will help you, such as a way to fix the BIOS. Remember to revert the boot order back to the way it was when you are all done.
I did some research around the interwebz and found a few different things for BIOS that won't load.
One is to disconnect the SATA cable going from hard drive to motherboard and then start the computer. If there is a problem with the master boot sector, this will bypass it, allowing you into BIOS.
I found another way to access BIOS and that is by restarting the system and as soon as the screen goes blank, hold down several keys at once. The intent here is to cause a keyboard error to force access to the BIOS. This does not always work according to it's author.
The BIOS is usually stored on a Flash memory chip on your motherboard.
To change the BIOS itself, you'll probably need a special program from the computer or BIOS manufacturer. Look at the BIOS revision and date information displayed on system startup or check with your computer manufacturer to find out what type of BIOS you have. Then go to the BIOS manufacturer's Web site to see if an upgrade is available. Download the upgrade and the utility program needed to install it. Sometimes the utility and update are combined in a single file to download. Copy the program, along with the BIOS update, onto a floppy disk. Restart your computer with the floppy disk in the drive, and the program erases the old BIOS and writes the new one. Be careful when upgrading your BIOS. Make sure you are upgrading to a version that is compatible with your computer system. Otherwise, you could corrupt the BIOS, which means you won't be able to boot your computer. If in doubt, check with your computer manufacturer to be sure you need to upgrade.
Admin, if this is wrong info, please delete the post. I apologize in advance if it is.
