'UPDATE PC (DOS) IRQ Clearing'
I think I've tried everybody's suggestions about sequence, value, timing, etc.
None of them work. The machine gets locked up, or 95 kills the DOS task,
or 95 gives a blue screen exception report.
I can't believe it's that tough! And going back to the first interrupt
controller only isn't a very feasible option.
Come on, guys! I'm counting on you...

if there is a 95 (maybe Win'95) as a framework, then you can forget the
whole stuff IMHO... :-(

It works fine for all except IRQ 9, which is reasonable to expect. Win95
is a nice conglomeration of DOS-support and protected-mode.
Sorry, Imre, but the world moved on past DOS a few years ago. I just
haven't plunked down the bucks for a new compiler (I'm running MSVC 1.5,
which is the LAST DOS compiler MS shipped. It's on my MSVC 2.0 CD) because
99% of what I do is on a PIC. Sometimes I have to make a driver for things
that go onto ISA backplanes (yes, I know, I should be using PCI). I
deliver a DOS prototype, and let the customer spring for the WinNT driver.
