A BIOS checksum error often occurs when you add or change RAM, or the CMOS back-up battery fails.

If this is the cause, entering BIOS setup, and just saving settings and exit will clear the error.

Since you are having problems with the W98 startup disk, I suspect that you may actually have a bad RAM module.
Start be simply re-seating your RAM modules.

As to the BIOS update:
Flashing the BIOS is NOT recommended unless the system functions normally!
If you have any problems booting, the flash process can actually fully disable your motherboard!!!

A DOS boot disk can be created by using the format option for the A drive from either My Computer, or Windows Explorer.
make sure that the box for make bootable is checked.

The error could be caused by bad memory chip or memory has crept out of slot and needs to be reseated
Open the computer case and remove the memory reseat in slot and boot computer.

Check to see if the computer is losing time,this will indicate that your battery is going and needs to be replaced.

The boot disk issue can be remedied by downloading from the following site www.bootdisk.com
