Having the board in front of me would help or even a high res image.

"The HAL driver supports the bidirectional port, and allows the user to
set the data group as either input or output. If configured as output, a
port provides a total of
So it is looking like the external resisters some how become disconnected
when you swap out the operating system? Interesting?
No, seriously, the hard part about debugging is that all the documentation
describe the INTENDED design and the way things SHOULD work. The first
step in debugging is
I just looked at the manual for the Moschip 9865 and there isn't any
mention of software select for the LPT signal pullups. It doesn't even
mention any being internally available.
Looking at the reference schematic they show that external 4.7K ohm
resistors are to be used on all the LPT pins

I am trying to use a PCIe duel parallel port card and I'm having some trouble
with it. It uses a Moschip 9865 according to lspci-v.
I have 2 different breakout boards, one is a CNC4PC C10 board and it works
perfectly fine with this parallel port card. The other one is one of those

Yes it's a standard pc with an onboard parallel port.
I have it configed as out with 0x0378 out.

Normal is where it was set.

These suggestions may be irrelevant, John. I've not had a full dose of
coffee.
Is the bios for this parport set to spp or out?
Have you tried inverting these pins using HAL's parport parameters?
I seem to remember that a couple of the pins you list were considered
inverted in hardware but
Amen on the coffee. Still on first cup.
Did you try the .hal equivalent of explicitly configuring the parport like:
loadrt hal_parport cfg=0x0378 out?
And as Rayh said, you might need resistors.
Is it a standard desktop PC with on-board parport?
Keep us posted,

I could not source enough current from my Parallel port for my
controll card to drive my stepper motor, so today, i added a new PCI
parallel port card.
