Award primarily sells it's BIOS to mainboard manufacturers who usually modify it somewhat for a specific mainboard. Contact your mainboard manufacturer for a BIOS update and the procedures for your mainboard. This is usually a free download of theBIOS code and the flash utility needed to install it. Of course, this depends on your confidence that the chip is OK and your mainboard is operating well enough to execute the flash procedure. Please be aware: A failed attempt to flash the BIOS usually results in a dead mainboard. Use extreme caution and procede at your own risk.

Flashing the BIOS should work.

Make sure that you have the correct file for your specific motherboard.

2 good sources for links to the motherboard manufacture are www.wimsbios.com
and www.motherboards.org

Keep in mind, that if the board isan OEM model, the only source for a BIOS file is the original system manufacture.

When flashing the BIOS, make sure that you have stable power so that the PC does not get shut down in the middle of the flash process.

You usually need to reset the CMOS memory after flashing the BIOS.

This may not be a corrupted BIOS.
There are several other things this could be.
Since it works after several reboots, it could be the heat expands something and the PC begins working.
Several reboots can also get enough charge in a bad battery toget the PC working.
A failing power supply can be very slow to become stable enough.
The most likely is the battery. Check it first.
THe next is the power supply. Particularly check the +5 Volt.
The next is a loose BIOS. Make sure it has not worked itself out, or has excessive dust on the leads.
After the PC has properly booted and then run for one hour, will it reboot properly when you push the reset button?
IF it does, the BIOS is very probably good, and the problem is somewhere else.
The other problems are a lot cheaper to fix.

When you got checksum error on a pc, I would recommend you replace your battery in your pc first. Knowing that you have done that then move on to the next part. Check your floppy drv & its cable connecting to m/b. On the other hand, if you do have another floppy drv, there is no harm fitting into it. It should start up probably.
Flashing the m/b bios ONLY if necessary. I would said try out the above ideas first b4 proceeding to flash your bios. Backup your old bios information b4 replacing with the new one.

Hope it work for you.....

Here is a site that offers programmed BIOS chips for under $25.
