Sounds like an SRM problem or EISA configuration problem.
Normaly the bus and then system board should be probed at this point.
We never used EISA on alpha before - EISA bridge support was only
conditionalisized on pci.

I tested localy on an AS4100 system:
eisab0: <PCI-EISA bridge> at device 1.0 on pci1
eisa0: <EISA bus> on eisab0
mainboard0: <DEC6400 (System Board)> on eisa0 slot 0
isa0: <ISA bus> on eisab0

What says show config and show device?

In case something is wrong with your eisa setup.
Eisa configuration has to be done via alphabios.
