I'm running Fedora Core 2 (i686), kernel 2.67-1.494.2.2.

The PC has a motherboard Parallel Port at I/O port 0x378.

I installed a PCI Parallel Port add-on card for some control
(not printing) applications. Kudzu automatically
configured parport1 at I/O port 0x9800 per the following
output from '/sbin/lspci -v':

02:02.0 Communication controller: NetMos Technology: Unknown device 9805 (rev 01)
Subsystem: LSI Logic / Symbios Logic: Unknown device 0010
Flags: medium devsel, IRQ 9
I/O ports at 9800
I/O ports at 9c00 [size=8]
I/O ports at a000 [size=8]
I/O ports at a400 [size=8]
I/O ports at a800 [size=8]
I/O ports at ac00 [size=16]

Port 0x9800 works fine for some apps, but other apps require an
I/O port address below 0x3FF.

How can I configure parport1 for I/O port 0x278 (as it would be
jumper-configured if this card were on an ISA bus)?

Thanks for your help.

Regards,
Charles Sullivan

You follow the exact same proceedure as if it was windoze: You don't, it's
a plug and pray device - you get a parallel port that's all you don't get
the ISA options.

Can you reconfigure the motherboard port for what you need, and use the
ports the other way around?

I should have thought, that by now, only assembly language programming
would be addressing hardware correctly. Other things would be using the
operating system to access *the port*, and let the OS worry about how that
works.

Thanks for your response Tim.

Yes, I could use the motherboard parallel port, but I need direct
port access and I'm connecting some experimental circuitry to the
port. I'm willing to risk smoking this (relatively inexpensive)
add-on card but am reluctant to risk my motherboard.

Thanks for your response Randy.

I guess I don't understand how this Plug 'N Pray stuff works.

In any event, I'm very surprised to find that Linux isn't powerful
enough to remap the port address to another unused address.

There is no such ability in PC's. No OS gives that ability.

If you have an ISA slot you can go that route otherwise you must use Plug
and Pray.

As per your other post stating that you don't want to fry your MB you have
two easy choices:

Add a buffer to your circuit (always smart).

Buy an 8051 USB adapter which is designed for design work ($40 and up).

If it's an experiment (i.e. something temporary), can you try disabling the
motherboard port, and seeing if your port card ends up with the addressing
that you need to play way?
