As it turned out, Buslogic recommend disabling all but one BIOS, and I 
assumed that the booting disk should have the BIOS enabled.
Booting VLB HBA I/O address 330 H, IRQ C(?), BIOS enabled,
non-booting ISA HBA I/O address 334 H, IRQ E, BIOS disabled.
I had to temporarily remove the VLB HBA and enable the BIOS in the ISA HBA to 
set the IRQ on the ISA HBA, then disable the BIOS and re-insert the VLB card 
(and re-insert the NE100I card next to it which had become partially 
dislodged). Afterwards, a second LOAD BT31X ... command line worked fine.
The old Python DAT tape backup caused a server crash though. My boss is happy 
to ditch the drive, backup tapes and choice of media in favour of something 
that is more reliable.
What backup media do you recommend that can backup at least 2 gig per tape? 
We have Arcada/Seagate Backup Exec and only need to backup the server.
