I have an IBM PC-AT with:
2 serial/parallel boards
and I want to use an INTERLAN NI-5010 ethernet controller.
The ethernet board can use either interrupt 3 or 5
However, interrupt 3 is used by COM2 and 5 is used by LPT2.
I only need one LPT, but I need both serial ports. Is there a
way of:
1) Disabling the parallel portion of the second board (I have tried
working with jumper J2, but it seems to mess up both parallel ports
when removed, or set to LPT1).
2) Buying a board for the AT that is only a serial board.
Please send e=mail to silber@tcgould.tn.cornell.edu. Thanks.

Go ahead and try the board using IRQ 5 with both LPT ports active. I have a similiar setup in my Novell network server, two network boards use IRQ 3 and 5, com1 using IRQ 4, and two LPT ports. I haven't had any problems with the setup with everything going at once. I remember something about the LPT ports that they actually did not use the hardware interrupts, but just the address lines and registers on each LPT board. Can someone add to this old memory?
