Folks,

I am trying to upgrade BIOS of my new assembled box by using the
bootable CD and system freezes with this error...

Roxio CD/DVD-ROM Boot Loader v1.01

0123Divide by Zero (935C:086c)
ROM-DOS Fatal Error! Internal Error! (3.398)! System Halted...

This CD works fine in another identical system and other bootable CD
work fine on this new box. So I have no reason to doubt the media /the
CD drive. I also swapped the memory from a known working system but the
error persists!

Has anyone come across a similar error?

Not for a very long time, but it used to happen with some software when
it tried to benchmark the CPU speed and the CPU was too fast for it. Or
maybe some CPU timing is actually a bit marginal anyway. Try using the
BIOS to back off the speed a touch?

BIOS flashing should be done from Floppy Disk IMO .. however that's a
PITA now BIOSs are starting to get up around the 1GB size ..

I've had all kinds of problems with trying to upgrade BIOSes with
DOS-boot CDs. Often they load them with an XMS memory manager for that
extra bit of memory for DOS, but this prevents the flash loader from
being able to flash the BIOS, because it puts the machine into Protected
mode, which stops the flash loader from having access to the appropriate
flash control ports.

These BIOS manufacturers really have to settle on a standard protected
mode flash loader for these things.

I don't think he's gotten as far as the BIOS update prog - looks more like
the DOS boot code has failed. If another "identical" system works with the
same CD-R OK, I don't see what it could be... unless they have different
BIOS versions?
