Richie,
I have a T20 and I would like to boot it from a USB device. However, when I go into BIOS setup, I don't see the option of booting from a USB device. There is a removable device but it points only to a floppy drive.
I believe my T20 has the latest BIOS: ver 1.22 IYET61WW which I downloaded and flashed on my T20 yesterday.
How did you get your T20 to see a USB device at boot?
