Well, after a bit of googling and searching in tyan.com (ftp and http),
it seems I'm out of luck: it's an OEM mobo, unsupported by Tyan. BIOS is
nowhere to be found.
As it looks like some other (supported) board has the same components
(S5211 for the curious), maybe I'll try to flash its BIOS if I get
bored.

Thanks, happy $CELEBRATION,
