yes, that is the likely cause

Swapping in an 80 pin cable should make that message go away
but "in general", it is merely an alert, that your devices
on that cable can then only run in ATA33 mode or lower. A
properly working motherboard, optical drive, and media
shouls still boot fine from a 40 conductor cable.

Have you checked/rechecked the jumper settings on the
drives?
Check voltage levels at the ATX connector and for the
drive(s) or at the very least in the BIOS as a start.

That could cause a problem but it's quite rare for that kind
of defect. Since your HDD was booting to windows, you could
try switching the cables, plugging the one for the optical
drive into the motherboard channel currently occupied by the
booting hard drive, since that channel has demonstrated to
work already. Also you can try booting the HDD from the
channel the optical drive is currently connected to, it
should still have a problem due to windows, BUT the key is
seeing if it starts booting windows at all, as that is the
first thing the system will do, look for and try bootable
devices after displaying the "verifying DMI pool" message.

Not a bad idea. You might boot to floppy and upgrade the
bios first, then clear CMOS, set bios to defaults & save in
setup menu. Also recheck the optical drive (and all other
bootable drive) settings. Set them to Auto and if there's a
"try other devices", try enabling it if not enabled already,
and you might try disabling other non-used boot entries and
move the CDROM drive up to the top of the boot order list.
ALso try unplugging the other device on same IDE channel,
setting optical to single/master jumper setting.
I suppose you're certain the drive was working (including
booting from same CD) prior to the motherboard swap?
