Windows + IRQ + PnP = big prob

[David Goodwin]

Hi,
one of my many probliems I am having with windows is that
it thinks that it is smart when it isnt. Windows has
decided that any device on my P3's motherboard is ISA.
Windows is even convinced that my PCI BusMaster IDE
controller is ISA, same with my VIA PCI to ISA brige (which
it also thinks is an ISA device). The other probliem is
that it is giving any thing that it thinks isnt ISA IRQ 9.
This means that my 4x AGP Video card is on IRQ 9, along
with my 6 channel sound card, GBit Network card, 56k Modem,
and my TV Tuner/Video capture card. This causes large
probliems. The video card should atleast have a
16bit(10-15) IRQ rather than an 8Bit(1-9), and so should
the Network card and Sound card. The probliem is that i
cant use most of these devices at the same time. 3D
rendering makes the sound go choppy, the Video capture card
wont run properly unless i keep the window moving, the
Network card cant keep constant transfer rates, and the
modem will only connect at 26.6k. I know that it isnt my
hardware because every thing runs perfectly under Linux, it
is just under windows that nothing works properly. This has
been the last straw for me and have moved to Linux for the
moment because my hardware works under it and it doesnt
give everything IRQ 9. I still use windows for some things
and it would be nice if my hardware worked under it because
that would make things much easier

Modern PCI cards are supposed to adhere to standards which
allow for IRQ sharing. It should not be a problem to have
many cards sharing IRQ 9, and I suspect you have some other
problem.

But, if you still are intent on forcing your computer not
to share IRQ lines, then you can disable ACPI which causes it.

WARNING: the following is at your own risk and will not
only disable IRQ sharing but many other ACPI functions.

Go into device manager under computer which I will assume
is ACPI Uniprocessor PC. Click properties|Driver and
choose Update driver... Next>>, and then choose display a
list.... option and Next>> Choose Show all hardware for
this device and choose Standard PC.

From your post 6 minutes after this one, I'd speculate that it isn't
W2k that thinks it's smart but isn't.

Sounds like your PC is woefully misconfigured. Probably starting with
BIOS settings and mainboard drivers. I'd go through the machine's setup
instructions, and all device setup instructions, VERY carefully. The
real problem with operating systems is that they do exactly what you
tell them to do, not what you wish they would.
