9.1. Choosing serial device interrupts
Your PC will normally come with ttyS0 and ttyS2 at IRQ 4, and ttyS1
and ttyS3 at IRQ 3. To use more than 2 serial devices, you will have
to give up an interrupt to use. A good choice is to reassign an
interrupt from your parallel port. Your PC normally comes with IRQ 5
and IRQ 7 set up as interrupts for your parallel ports, but few people
use 2 parallel ports. You can reassign one of the interrupts to a
serial device, and still happily use a parallel port. You will need
the setserial program to do this. In addition, you have to play with
the jumpers on your boards, check the docs for your board. Set the
jumpers to the IRQ you want for each port.
You will need to set things up so that there is one, and only one
interrupt for each serial device. Here is how I set mine up in
/etc/rc.d/rc.local - you should do it upon startup somewhere:
/etc/setserial /dev/cua0 irq 3 # my serial mouse
/etc/setserial /dev/cua1 irq 4 # my Wyse dumb terminal
/etc/setserial /dev/cua2 irq 5 # my Zoom modem
/etc/setserial /dev/cua3 irq 9 # my USR modem

By rebuilding the kernel, configured for HPFS support. Everything you
need should be in /usr/src/<version>, including the docs.

Hmmm... OS/2's boot manager seems to be no good with operating systems
it doesn't know about. You could configure LILO as secondary boot
loader on your Linux root partition, and mark that partition active.
Then tell OS/2's boot manager there is something to boot from that
partition.
Or you could boot Linux using Loadlin and a dos config.sys menu, which
means using dos/Loadlin as a secondary boot loader. Take your pick;
or maybe someone else knows better. I never tried running OS/2 and
Linux on one machine.
Good luck,
