Windows Interupt help

[bloodline]

I've upgrade my Motherboard, but kept my old WinXP installation... but that instalation doesn't recognse my New APIC, and so is only using IRQs 0 to 15... how do I get Windows to forget about my old Mobo, and use all my new ints?

Sorry I can't be helpful, but I've never gotten XP to work with a new mobo.  I always have to re-install.  The same is NOT true of Win2000.

Anyone have success with XP and new mobos?

Give it up, Matt. Re-install the crap again!

Have you tried to delete EVERYTHING in the device manager and then rebooting?

bloodline, is the APIC enabled in the BIOS?

Also - an APIC doesn't necessarily mean better performance or even better anything.  I wouldn't get too cut-up about it if you can't get the system to work properly with it.  I tested my Asus A7N8X-E Deluxe mobo with the APIC enabled, and none of my tests showed a performance increase, and there was an annoying onboard sound issue which could only be resolved by disabling the APIC.

I think the idea of the APIC is a step in the right direction, but it hasn't yet become a universal significant benefit.  Kind of like SATA :-)

As for reinstalls - you can just change the HAL and reboot.  In Device Manager > Computer > Update driver:

Advanced Configuration and Power Interface (ACPI) computer (this is just plain normal ACPI)
ACPI Uniprocessor PC (this one is ACPI + APIC)

It is possible that you'll have to reinstall other drivers afterwards, but I haven't had to yet.

Ok, I just noticed this:

Cardinal mistake.  Do not pass Go, do not collect $200 :-)

Have fun reinstalling (I'd advise a clean reinstall).

Yup, Enabled and is used by WindowsXP x64 on it's own partition.

Yeah, I know, it just makes me happier to have 20+ interupts.

Yeah, I have installed all the New chipset drivers, but sadly the ACPI is wrong, as the Win32 XP can't shut down the computer (Where Win64 XP can).

Gah... you're useless! :-P

I'm not going to reinstall... not until WinXP64 is officially released. :-D

At the moment I'm doing a slow migration to the Trial version of WinXP64 via dual boot, I can't use XP64 in full yet as some of my hardware doesn't have drivers for it.

Ok, How about I boot from the WinXP CD and run the "Repair" option?

Anyone know exactly what that'll do?

It reinstalls Windows but keeps all user accounts and programs. You'll need to renter your product key and reactivate windows.. It works, but not the same as a clean install.

Mind; do pick the second repair option (The point when setup has looked for existing installations), not the repair console

[GadgetMaster]

A repair tends to keep the drivers intact. You can try but I doubt it will help. It takes the exact amount of time that a re-install does. So not very convenient either.

I had trouble with XP Mediacentre 2005. It just kept hanging near the end of the installation so I just reformatted and put XP pro back on. Bugger it!

What's the 64bit edition like?

[mikeymike]

Did you try changing the HAL to what I said?

(Not the chipset drivers, though they would need changing for the new mobo)
