IRQ=4, COM 2&4 use IRQ3
I never understood the history of 1&3=4, and 2&4=3 ?
Surely when they first added COM ports they would have taken the first
available IRQ, and that would have been 3 ?

I got this one right.

here I go BBSing again...

Back when I ran a BBS I had one machine, two modems...mouse was on COM1, and
the BBS modem was on COM2...I had to put the 2nd modem on COM3, but would
share an IRQ with the mouse, so had to get the tweezers (if my nails weren't
long enough) to change the jumpers to put it to IRQ 9 (the only free one
back then) and it worked fine.  But, this was back when modems actually HAD
jumpers or dipswitches.  I remembered the IRQs because Com1 is an even IRQ
and COM2 is an odd IRQ.  I believe IRQ 1 and 2 are reserved, so 3 & 4 were
and easy way to remember it.  9 was usually open, and I seem to remember 7
also, but again, I am probably wrong about that.  It's been a while since
fiddling with IRQs.

But I picked the first one as 4...But then realized that it should have
probably been two...

Number 3 no clue, maybe command.com config.sys and autoexec.bat?  I thought
command.com HAD to be on a floppy to get to a DOS shell...but I'm frequently
wrong...

but number 4 is easy!

Format C and install Linux  and while you're at it, format the other
machines and install Linux too! </joke>
