I've got a Win2K system where shared interrupts are causing serious non-
functionalities. I've got devices only operating intermittently if at all,
apps which won't run, devices which Win2K intermittently detects as
removed. I get delays at boot time, miscellaneous locks, and various other
errors which I've been able to track down to the problem of shared
interrupts. It was irritating in the past but it's reached the point where
something has to be done.
But meanwhile, a complete, from-the-ground-up reinstall isn't an option.
That would be the easy way - reinstall with every power-saving option in
the BIOS turned off. In fact, when I did the original install I *did* have
all power-saving options off - or so I thought. Turns out the 2K ACPI
detector is *much* more aggressive than one might imagine and if you allow
it even the slightest hint that ACPI might hypothetically be an option, it
enables it. GRRR!
Anyway, I need to disable shared interrupts so I can assign everything in
such a way that my devices don't trip over each other. And I need to do it
without reinstalling. What do I need to do? I know I'm going to have to
replace the NTOSKRNL and HAL (which I can do from my bare-bones service
install on the same machine). But then I assume there are multiple registry
entries that also need to be changed. So what are *all* the things I need
to do (whether copying files, editing the registry, editing text files, or
whatever) in order to disable shared interrupts?
