My English is not very well so sorry for that

First; Since the last days i've bought a used ThinClient...there is no CD-Rom, no hdd and no floppy in it, so my intention was to flash the bios to boot from usb, because i think with the current bios version i can't boot from usb!
So i search for the manufactor of this board and i think i've found him. It is Global Circuit Technology! I searched for bios updates from this manufactor but i dont find anything!
i have the award bios id:
05/22/2000-GXm-Cx5530-2A434G9HC-00
maybe u can help me!
thx!
