Greetings,
I am trying to get my new Universal Stepper Controller working with my PCI
parallel port but I can't seem to set my PCI card to EPP mode. 'pcils -v'
reveals:
08:00.1 Non-VGA unclassified device: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 1 (parallel port) (rev 01)
Subsystem: Oxford Semiconductor Ltd Device 0000
Flags: medium devsel, IRQ 18
I/O ports at c050 [size=8]
I/O ports at c040 [size=8]
I/O ports at c000 [size=32]
Memory at fb100000 (32-bit, non-prefetchable) [size=4K]
Capabilities: <access denied>
Kernel driver in use: parport_pc
Kernel modules: parport_pc
I have tried using Jon Elson's 'pcisetup' and Kirk Wallace's 'showport'
program. 'showport' seems to expect a range of addresses for the base and
extended modes, but the output from 'pcils' only lists 3 addresses, not 4,
which I assume is the beginning address of the extended mode?
I also tried starting LinuxCNC with Pico System's sample config files for their
Universal Stepper Board. I have been advised that LinuxCNC will attempt to put
the port into EPP mode, but LinuxCNC is falling with this message:
Can not find -sec MOT -var MOT -num 1
Can not find -sec IO -var IO -num 1
Can not find -sec LINUXCNC -var NML_FILE -num 1
Can not find -sec EMC -var NML_FILE -num 1

See the output of 'dmesg' for more information.
Any suggestions would be greatly appreciated!
