Are you sure it's an 825? The reason I ask is because the 825 chip is
both a SCSI chip and a PCI chip with on-board BIOS. The only real way I
could see it working as EISA is if it were glued to a EISA<->PCI
converter, which I didn't think existed.
Also, the only way to get this to work will be to find out what the
magic glue registers are and how they're mapped ... unless you have
access to the HW specs for the box, this is going to be tricky to
reverse engineer.
