Yup, got 3 on one (RH 6.2 with 2.4.18) at the moment with no modification.
I believe I read that that was the limit without changing something in the
kernel code, but I haven't confirmed it.
If you're using an ISA card with manual settings, you shouldn't have much
of a problem. Just chuck it in and the system should detect all the ports.
You will need to be sure you have enough IRQ's/io ports and that are they
set correctly. If it's ISA PNP, I'm not sure, but it's probably handled like
the PCI below.
If you're using a PCI card, my experience is that it's a bit of a different
ball game. Since all the add on PCI parallel port boards that I've seen
are PNP, You must determine the IRQ and/or io port on the card that you wish
to attach to a given lp port using information from the boards manuf. and
/proc/pci. By this I mean that it may not be obvious which io port on the card
is to be used as for a parallel port. My dual port PCI parallel card shows
up like this in the /proc/pci:
Bus 0, device 5, function 0:
Communication controller: PCI device 9710:9815 (rev 1).
IRQ 20.
Master Capable. Latency=64.
I/O at 0xfc70 [0xfc77].
I/O at 0xfc78 [0xfc7f].
I/O at 0xfc88 [0xfc8f].
I/O at 0xfc90 [0xfc97].
I/O at 0xfc98 [0xfc9f].
I/O at 0xfcb0 [0xfcbf].
You must have the manuf. specs to know. Also, not all PCI parallel/serial cards
are supported, although thanks to Tim Waugh of RH, many (most?) are. Note also
that moving a PCI board usually/always (??) changes the io ports.
In either case you must set the IRQ/io ports in your /etc/modules.conf. Mine
looks like so:
-------------------------------------------------------------------------
#
# Current Parallel setup! Be Careful; Very Careful!!
#
# Note: Anytime the PCI parallel card is moved to a different
# PCI slot, the io ports change. Check the /proc/pci
# file for the new ones....
#
alias parport_lowlevel parport_pc
options parport_pc io=0x378,0xfc70,0xfc88 irq=7,none,none
