Well, I solved the problem the USB parallel printer adapter
problem. It was an IRQ conflict. If I disable a SCSI controller, it
works fine.
Which leaves the problem - how do I enable all the devices in my
system? And what do I do if I want to add another one?
The BIOS allows me to force the IRQ of any of the PCI slots. In the
PCI slots I have an AHC2940 (slot 4), an Intel EtherExpress (slot 2),
and a BrookTree TV tuner (slot 3). Slots 1 and 5 are empty. I believe
(not got the BIOS PCI/PnP stuff in front of me for some reason) I can
force PCI slot IRQs to any of 14, 12, 11, 10, 9, 7, 5, 4 or 3. The
ones that *aren't* PCI slots on that list are 14 (ata), 12 (psm), 11
(motherboard ahc, shared with etherexpress in slot 2), 10
(soundblaster - moved off of 5 while I was fooling with the system), 9
(usb) 7 (ppc), 3 & 4 (sio ports).
Anyone got any advice on how to shuffle the IRQs around amongst the
three PCI slots to get a system where everything works? I've attached
both dmesg output and the config file. Maybe this should be sent to
-hardware (but I'e already asked about the printer here)?
Thanx,
<mike
