This sounds like it might be a cabling or termination problem. Please
remove all devices from your SCSI bus except your boot disk to try to
isolate the problem. Does doing this work and let you set a faster transfer
speed? If so, continue adding devices until the problem occurs again.
The newer AdvanSys driver may indeed report a BIOS address of 0, but this
does not indicate that the board hasn't been initialized. Like all SCSI
adapters the BIOS is only used at boot time to load the linux kernel into
memory from the boot device (using the INT 13 interface). When you see
the AdvanSys driver banner the BIOS has finished executing a long time
ago.
Can you please give the exact text of the 'unknown warning 40' message?
If it's from the AdvanSys driver, it should be preceded by something
like "advansys: "
