R30 / R31 PCI (IRQ) assignments in WinXP

[Thane_Bitter]

I am trying to solve an issue with the assignment of IRQ's on my machine. Currently, according to Hardware Manager, every PCI base device is attached and running on Interrupt 11 (IRQ 11). This includes: Display adapter, wired & wireless cards, the PCMCIA bus and the USB bus system, and the sound card.

If you have a R30 or R31 series ThinkPad that is running Windows XP, would you mind letting me know what your IRQ assignments are. The procedure to check is very simple: open up Device Manager, click "View" on the menu bar and select "Resources by Connection", finally click on "Interrupt Request (IRQ)" which will expand the list of devices.

Thanks

I've got an R30 that has the same settings under BIOS..
All devices on IRQ11. I think that is the default as other models i have are using the same settings. (T30/A30/A31)
I dont believe that there should be any problem except if you use a custom device (wireless/modem etc)

Interesting, thanks for the information. Actually, your guess was correct; I am trying to run a different wireless card that is not original to the machine. I am having some difficulty with it (whole system will hang while playing video when connected wirelessly), I was hoping that the IRQ thing was the cause.

what wireless card did you put in? Rosh (r2d2) and I have found having weird locking up issues with internal wireless cards on the r31 on a previous thread

Yes, I did a search for wireless card options and the lockup issue appears in everyone that has tried to upgrade or use another wireless card.
It is a (looks for FRU number) IBM 11a/b/g Wireless Mini PCI card (FRU 91P7301), and uses the Atheros chipset (I neglected to record which chipset ). I have not had a chance to fully play around with different configurations (i.e. clean recovery install, clean OS install, 3rd party drivers, etc). The card is function for simple surfing of WebPages, network browsing and so forth; again, I have not had time to explore all my options. The "lock-up" seems to occur only on videos, such as one embedded in a webpage (YouTube/Google), streaming videos (as viewed via Windows Media Player 11), or accessing stored videos from a network drive.
The lockup is quite bad, I mean as soon as it happens the whole system ceases, not event the caps lock indicator will light up.

I have found only one reference for solving this issue, actually it was on this form, one user (I think I was Desi), claimed that after a clean install (the user was using Windows 2000, the service pack level was not mentioned), and by added the /PCILOCK command to his boot.ini file, that the issue was solved. I attempted the boot.ini file modification; however, my machine stopped loading XP. I also tried to adjust the PCI IRQ assignments in the BIOS but that also failed.

I have an old hard drive (original to the system, but started to fail and was replaced), assuming it still runs, I should be able to try some more experiments.

I must say I am slighty disappointed, though not surprised with this issue. I suspect the true fault is not a driver or OS problem but something in the main board itself. Pity too because the R31 BIOS is not locked down to prevent non-authorized cards.
