Use only the original 68040 library v37.30 that comes with WB 3.1 disks
Let's give an end to this 68040.library myth, shall we? :-)
The BPPC will always use the library which is stored in the flash rom of the card. Any 68040.library in the LIBS: will be ignored.
I will agree that the biggest enemy of the card's stability is heat. I have applied active cooling in the 2 CPUs and the GPU, and my BPPC/BVision combination is fairly stable.
