Neither is working.
The bios states it can boot from HDD, CDROM and also a mysterious "removable device", which I thought was USB. The bios vesion is 0208 from American Megatrends.
I also tried Plop Boot Manager - to no avail - no inserted USB key drive is found. Also Super Grub Disk 1 did not work.
I have to boot from USB, CDROM doesn't help me due to file system limitations (frankly, I want to boot to Chrome OS).
Can anybody help me out here? Has anyone managed to boot from USB with that gear? It would be really appreciated since I'm trying and researching since an eternity.
