This is the "standard" evidence of the ROM-mapping bug in the 3c905b
card.  The file "3c90x.txt" in the Etherboot distribution explains the
solution used by Etherboot -- it involves booting the machine from the 
diskette image of the ROM first, which resets a configuration register on 
the 3c905b so that the ROM-mapping bug is worked around.  Once that is
done, the machine should work normally, until 3c90xcfg is run and the
transceiver type changed back to a "normal" value (for some reason on the
3c905b the transceiver type setting affects the mapping of the ROM....)

Greg.
