IRQ problem with Gigabyte 8SRX

[dnd728]

Hi there,

I have a strange problem with my Gigabyte GA-8SRX (Updated BIOS) - Nothings is working right with IRQ 12. No matter what slot or onboard device - they would be recognized by windows, but would not be completely functional. When assigned any other IRQ they would work perfectly. For example:
Modem A - would answer ATI query and would pick up the line, but would not be able to dial, only make tick noise.
Modem B - would install fine, but not even answer the query.
Soundblaster - installs fine, but only makes clicks. Nothing else.
Onboard USB - only one attached device would work.

I wrote Gigabyte about it a couple of times but received no response.

Does anyone have an idea what could cause this?
Is there a way to leave this IRQ unused? (Besides buying another card and assigning it to IRQ 12)

Thanks in advance for any of your comments,
dnd

This dude Promethus has done extensive research on the 8SRX. Also, post your question there as well, since there is a big community of 8SRX users that might be able to help you.

Connect a PS/2 mouse. Or set IRQ12 to "reserved", either in BIOS, or in Windows Device Manager.

Problem sounds like BIOS doesn't take IRQ12 off the legacy PS/2 mouse controller correctly for when no mouse has been detected. This then messes up correct operation for PCI interrupts routed to IRQ12.

Thanks, both of you!

I went to asusboards - nothing yet, but it does seem useful.

Adding a PS/2 mouse did help, but I can not find any place to reserve IRQ12 in neither BIOS nor Windows (XP).
Nor is there a place to deactivate PS/2.

I am using the latest BIOS F9.
Anybody knows where to reserve them?
