Excellent - I can provide clients with a "will boot anything" disk so they
can check to see if Etherboot supports their NICs.  Now, if only the PCI
spec could change so that the same ROM image can work when placed in any
NIC...

I assume you'll be keeping the current scheme as well - the most usual
number of drivers in a ROM will probably be 1, 2 or all of them.
