I am experiencing a sever problem in booting my machine. I have a 1.80 GHz Pent.4, 512 Ram, 8K Pri. Cach3, 256K secondary Cache, 60Gb HD, CD-Rom, CD-RW Rom and a 3.5Floppy.
Half of the time on start-up I get no further than the negative screen comes alive and this appears:
Award BootBlock Bios v1.0

BIOS ROM checksum error

Detecting floppy drive A media...
INSERT SYSTEM DISK AND PRESS ENTER

If I insert only the first (1 of 6) XP-SP1 Set Up Boot Disks I can turn off the machine as soon as it request the second disk and it will boot normally. The other half of the time the machine will boot when first turned on. There are no beep tone errors on start-up.
I have reformatted my HD and reloaded XP-Pro and have tried adjusting the boot device sequence in the Bio all with no results. New battery has been installed. All with no effect on the problem. It will boot normally if I turn off the machine and turn it back on immediately. If I allow it to sit for a while (cool down??) it will not boot. I am at the end of my limited knowledge, my wits and patients. Any and all suggestions will be most appreciated.
Thanks, Ed (eddie460@comcast.net)

You might test your RAM. Simmtester.com has an excellent program you can download called Doc Memory. If this shows your RAM to be good, I would suspect your mobo.

You're going to want to download a new BIOS file and reflash your BIOS. Make certain that you are flashing with the right BIOS file.

First, disconnect the power cable to your PS, then switch the jumper on the mobo to clear the bios. Wait about five or ten seconds then put everything back together again and reflash your bios. After flashing, shut down and clear the bios one more time. After that, you can set your bios back up how you wanted it and you should be good to go.

Just fixed one with this problem. New battery and flash the bios to current.
