The one with the riser/fpu/nic, also was the only machine out of the 5 to have a ROM simm installed,

one of the other macs wasn't booting, so i pulled the ROM simm out of this one, and installed it into the one that wasn't booting

now all 5 boot and work, i just wonder if that rom simm was installed into the one with the riser for a reason,

i dunno, maybe i should do some more testing maybe the fpu or nic doesn't work with out that rom,
