Many motherboards still have an "ISA Bus" that has a few onboard peripherals
such as a parallel port and an RS232C port and some other things that work fine
slowly.

It won't show a standard onboard motherboard port, because those are not on

I thought I'd try that on my LinuxCNC system. With or without sudo it does
print a list of all the devices but it doesn't tell me the actual port address
of the standard port on the machine (0x378) which I know because when I dual
boot it into MACH3 instead of Linux and move the parallel port cable from the
MESA to the back of the machine it works with that address.
I haven't run it with the back of the machine in Linux for a while but the hal
file uses cfg=0 for the standard port and when I had a second PCI card
installed it was cfg=0x2000
