Hi Trevor,
I happen to have the same no-name motherboard as you ("P5TVX-AT," Intel
Triton II chip set, P100, Award BIOS V1.0A, 1996) as well as an AHA1542CF
and NE2000 clone. I had similar problems to yours. I solved it by
moving the base and IRQ for the 1542CF to base 0x330, IRQ 11, DMA 6, and
marked this IRQ as well as my NE2000's IRQ (IRQ 10, base 0x300) as
"Legacy IRQ"s. I'd noticed that the ordering of the boards determined
which failed to respond to IRQs (usually the second board in the ordering
was the one to fail). If you have any other boards which aren't strictly
PnP (perhaps your soundblaster?), they should be marked as Legacy IRQs.
Other settings for the 1542CF:
Host BIOS Enabled,
Parity Enabled,
DMA Transfer 5.0Mb/sec,
Host Termination Enabled,
switches: all off, except for sw5 (Disable Floppy)
Suggest you run the Host Diagnostics for the 1542.
Good Luck!
