That would indicate that this will have been using the ISOLINUX boot path, because as previously noted, this motherboard has a BIOS; if my memory is correct it predates UEFI entirely, and at the very least I've seen zero indication that it has one. > Up to recently it was rare to see ISOs which boot from legacy BIOS via > GRUB.

I'll probably find time today for another shut-down and swap-out to test with an ISOLINUX-only boot medium; contrary to what I said in a previous mail, I'm not positive that I have any of them on hand at home, though I have plenty at my workplace. If I do test it, I'll report back here. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
