Flashing the Tyan S2642?

  e-mail acct. ]

Last weekend I was looking at installing LinuxBIOS on my Tyan S2462,
and got to the point of building the romimage, but couldn't figure out how
to flash it.  devbios (from CVS) reported (in /proc/bios) that it was an
unsupported Macronix part, and flash_rom (from linuxbios CVS) didn't
appear to recognize it either.

Am I doing something really stupid or simply looking in the wrong place?

Thanks,
