Oddity booting Knoppix on Supermicro H8DMU+ board

A few .cfg files in the /boot/isolinux folder of ISO image file may interest you a bit. After seeing another successful case of making a bootable usb device with unetbootin, I am curious about how unetbootin works and cannot find a full set of its user's manuals as well. From the brief summaries on its sourceforge website, I guess it is kind of a boot loader installation GUI which uses either Syslinux or GRUB (in general) as the backend. If so, installing the boot loader directly from terminal with appropriate arguments should be feasible in your case. By the way, you could also try out the very first KNOPPIX USB device in question on a less cutting-edge motherboard to see if the glitch is reproducible.

ATB,

This board is Socket-F: old enough to have been out of production for ~5 years. You can't even buy them from Supermicro at this point.

At some point I must have seemed annoyed enough to satisfy the poltergeists: After one last hard-reset (remove battery & short the
leads with a screwdriver) the existing unetbootin+gentoo install loaded the kernel as usual and I'm running again.

Same thumb drive.
Same reset to failsafe defaults.
Same re-configs of fan, etc, in the bios.

Poltergeists.
