The Macronix chip is a Tulip work-alike, with some changes in the media
selection registers.  The first 12 registers are very similar to the 21140.

Usually 'cc' is a link to gcc
beta$ ls -atlr /usr/bin/cc

Your BIOS isn't assigning an IRQ.  Change the "PnP OS" (a misnomer) field,
or a field that relates to IRQ assignment, in the BIOS setup.

It's curious that your PCI BIOS uses IRQ255 to mean no IRQ assignment.  This
is the correct value, but most x86 BIOSes use IRQ0.
