Windows 2000 and Windows XP create "virtual" IRQ's which allow you to shove as much hardware as physically possible into the PCI slots. It has no bearing on the number of processors, as a previous poster has stated. (At least in the case of Windows 2000 and XP.)

I doubt if having IRQ #'s > 15 is your problem. I'm running RH 7.3 on an IBM Intellistation and have devices on IRQ's as high as 22 with no issues specific to the motherboard. -Steve -----Original Message----- From: Jeffrey Lawton [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 25, 2003 12:09 PM To: [EMAIL PROTECTED] Subject: Hardware IRQs above 15 - new/unsupported Intel motherboard? Hi all, I'm a longtime embedded/test programmer but still a bit of a "newbie" to Linux so bear with me. (I tried some of this out on the "install" listserv but they acknowledged a lot of this was "over their heads" which is why I'm here) I just bought a new 2.4 gig P4 system with a nice Intel D845PESV motherboard (sometimes they put an "L" after that too, I think that means it's got Analog Devices SoundMax and a NIC onboard as well). Well, first I installed Win2K on it and everything is working fine no problem. But when I tried to get RH8 running, some items seemed to install OK whereas others were giving all kinds of problems (like the soundcard, modem and network adapter, although the external FireWire card came up fine). Missing/out-of-date drivers? Whoa, not really, it gets more interesting! When I booted back into Windows and looked at the Win2K Device Manager, imagine my surprise when I noticed the following assignments: SoundMax Integrated Digital Audio - IRQ 17 Intel 536EP v.92 Modem - IRQ 19 Intel Pro/100 VE Network Controller - IRQ 20 (yeah I know it's just a cruddy HaM winmodem, PLEASE don't reply just to remind me - installing hamcore/ham just confuses the issue and addresses the wrong problem!! - when I get serious I can go out and upgrade to a regular "DOS-compatible" job) Kind of interesting (to me at least), typically "PC-compatible" meant hardware interrupts went up to 15 AND STOPPED. And this list corresponds very well to the devices I'm having trouble installing! Has anyone else seen this before? Know what it means? Am I going to have to wait for RH9 for support, or - this really worries me - does this mean my brand-new, less-than-a-month-old motherboard is already an unsupported orphan? (Would anyone from Intel care to comment - uh - would they dare?) Is there a beta version of the OS or parts of it addressing this issue that I could help test maybe? (I also noted that in dmesg it complained about "unknown bridge resource 0 - assumed transparent" which might also mean something to someone) Eager to hear what anyone can contribute to help shed some light on this.
