HELP!!!!

I built a home-brew MIDI interface for my synthesizer setup.  When
I built it, I had an old PC-XT clone.  I hooked up the receiver
section of the interface's UART chip (8250) to IRQ2.  This worked
just dandy.

Now I have a 386-SX system.  IRQ 2 doesn't work anymore.  All docu-
mentation I have read has said that IRQ2 is a "cascade" interrupt.
WHAT DOES THIS MEAN, AND HOW DO I MAKE IT WORK????

In an effort to speed up my success, I rewired the interface so
that it would use IRQ5 instead of IRQ2.  Still no interrupt response.

I took the software I was using on the old system (which I wrote),
and re-compiled the .ASM files which handle the interrupts so that
they would use IRQ5 instead.  Total death.

Any help would be appreciated.  The system I have is a Goldstar with
2 serial, 1 parallel, 1 game port, 40 meg HD, 2 floppy drives, VGA.

Thanks in advance,

Matt K.
