I was browsing thru the hardware manual of the BT 445S and there it was on the next page :-( I was just misguided by the nice switches on the card edge. To set the interrupts not only the dip-switches need to be changed. More important is the actual and physical connection of intr 12 to the ISA bus connector. After taking the board out, and really connecting intr 12, the system booted the BT kernel without a glitch. I'm now compiling a new kernel with all our options set as we'd like them to be. The current config: 16 Mb BT 445S with intr 12 and switch 2-10 in default state, giving dma on channel 5. Things I'm going to test: toggeling the 2-10 switch adding 16 MB more.
