Hope someone can help me with yet another DRIVER_IRQL_NOT_LESS_OR_EQUAL problem. Earlier this year I installed XP Pro on my D: drive, so I now have a dual boot system with 98. I've been testing XP now and then and using it for processing video files and storing over 4GB files on an external USB NTFS drive, but still use 98 for most other things such as gaming, internet, etc. A couple of days ago I went to burn a DVD video in XP and got this error. It used to work ok, but it's been a while since I did any burning in XP so I have no idea what's changed since then. I don't believe the problem is hardware-related, as I can burn in 98 with no problems. But using the same type of blank DVD's with the same version of Nero (220.127.116.11 Ultra) in XP results in this error occurring after about 15%. I discovered it was using the Nero ASPI, so I got rid of it and installed ASPI 4.71, but got the same problem. I've also forced XP to use the same IRQ's as 98 by selecting PIC and non-plug-and-play in the BIOS as suggested elsewhere, but again to no avail. The BSOD does not mention any drivers, so I don't know where to look next. The last message was *** STOP: 0x0000000a (0x80AB2EFC, 0x00000002, 0x00000001, 0x804E2EED) Event Viewer does not report anything corresponding to the times of these crashes. The only other option I can think of is to do a reinstall/repair, but I'm hoping someone here can give me an alternative before I try this as a last resort. I've attached my last 5 minidumps. Hopefully someone here will be able to interpret them, as I've got no idea.
