BIOS is very much an i386 PC mother board thing. 99% of embedded
computers don't have a BIOS. Probably the only reason BIOS is used is
to ensure that the serial ports are placed at the address that M$
Windoze knows to find them. eCos does not need this limitation.

Keep searching and hopefully you will find either a data sheet or a
*nix driver.
