IRQ Request Table for T2P4

[Roman]

Hi,

Does anybody know the IRQ Reuest Table for this "oldie"?
I know that PCI Slot 4 is shared with the USB controller.
Do any other slots have an interrupt channel on their own.?

I'm using a ISA sound card in the system, does it make a difference?

Config:
PCI 1 Voodoo3 2000
PCI 2 NIC
PCI 3 SCSI controller
PCI 4 Free


I like to change the NIC in slot 2 with a AVM Fritz DSL card, which
need a interrupt channle on its own.


Thanks

I'm not abolutely sure what you want to know, but:

1) Every single PCI-slot is configurable to get an auto-assigned IRQ *or* you
may assign an IRQ by yourself in the BIOS settings.
2) There are no BIOS-limits for IRQ sharing: You my assign the same IRQ to one
ore more PCI slots (I have never had problems with IRQ sharing on this board)
3) auto-assigning IRQs may also assign the same IRQ to more than one PCI slot if
there too few free IRQs (eg if you reserved some IRQs for ISA use in the BIOS
settings)
4) If you want to preserve your current IRQ settings (eg for OS reasons) you may
want to find out what IRQ is currently assigned to your NIC and manually assign
it to the slot your NIC is in. You should not notice any differences int the IRQ
assignments this way. If you then change this card by another one the new one
will get this very same IRQ. If there are no limitations that prevents the new
card from running with this IRQ everything will work as before.

He's looking for an IRQ routing table, like those contained in the
manuals for newer Asus boards.

I think it will be hard to find, but it can be constructed as by experiment
by moving cards around and checking which slots and onboard devices share
irq. Multifunction devices that demand 2 irqs are to be avoided in the test
phase as it can be harder to construct the table with them present.

I would recommend, studying the PDF Manual from www.asus.com.tw

PCI Four, as I know, is also with the ISA-Slots (PCI-ISA Bridge). But
an Isa Soundcard will not share the IRQ with PCI Slot 4. But any other
PCI Card in Slot 4 will disturb (IRQ-Sharing) a fluent OS!!!

I also had the T2P4 and so far as I know PCI 1,2,3 is free. 4 is
shared, if used.

You can also reassign the IRQ used. In BIOS!

Just change the NIC with the AVM. It seems that this will work.

Don´t forget to look after starting your OS, which IRQ are assigned.

Also a good tip is: disable all possible PWM and ACPI Modes, so that
you get IRQ9 released, where it would be highly recommendable to place
your Voodoo3 2000. "IRQ assigning in BIOS"
10- SCSI
11- Fritz
12- PS/2 Mouse (If you don´t connect a PS2 Mouse, you could also assign
this IRQ for your needs)
I have both, USB and PS2 Mouse, DOS-Windows ;-)
5- Sound
4 or 3- USB (disabling one COM Port for USB)

9- VGA


Good Luck,

P.S.: If you use WinXP, 2000, 98, ME, you will also need to disable
ACPI. Otherwise you always have IRQ-sharing even if your Hardware Setup
is perfect. Then you have all devices on IRQ9 and the software (OS) is
doing the IRQ managment - what a stupid solution!!!

Duh. I could have thought of the FAQ...
