Hi,

I'm trying to get a PCI-express add-in parallel port card working with
7.0-STABLE, and after trying the following, I'm unable to get it to
attach to the ppc bus. The card has a "MosChip NM9805" chip. Motherboard
is an ASUS P5E64 WS. (which of course has no on-board parallel port).
The card seems to be recognised by the puc layer.

I've added
device puc
to the kernel config file, and added

{ 0x9710, 0x9805, 0xffff, 0,
"MosChip NM9805 Dual 1284 Printer port",
0,
PUC_PORT_2P, 0x10, 8, 0,
},

to sys/dev/puc/pucdata.c and with verbose booting, get the following
extracts from dmesg: (full dmesg attached below)

pcib3: slot 0 INTB hardwired to IRQ 17
pcib4: slot 1 INTA is routed to irq 17
pcib5: slot 0 INTA is routed to irq 17
pcib6: slot 0 INTA is routed to irq 17

[ and later ]

ppc0: parallel port not found.
ppc0: <Parallel port> failed to probe at irq 7 on isa0

Any suggestions would be appreciated.


Take a look in /boot/device.hints
Do you have any lines in there referring to ppc0 ?
If so try commenting them out.

Thanks for the suggestion, Erik.

I commented out

hint.ppc.0.at="isa"
hint.ppc.0.irq="7"

from /boot/device.hints and that got rid of

ppc0: parallel port not found.
ppc0: <Parallel port> failed to probe at irq 7 on isa0

from dmesg, but unfortunately nothing else changed.
