So I installed my brand-spankin' new 2500A into my rig tonight, and all seemed to be going well... until I tried to burn a DVD. Blue screened about 4 minutes in.
I read through the NEC FAQ/Troubleshooting guide, made sure DMA was enabled, using standard Microsoft IDE drivers, etc. IMAPI service is set to manual. I deleted the drive from Device Manager, rebooted, got the same result (now two coasters. :-/)
Then I took another look at line (5), "Uninstall Intel Application Accelerator." Sure enough, I'm on an 875 chipset, and using the onboard I/O controller (2 SATA, 2 IDE) with the Intel Application Accelerator RAID edition installed and running.
Problem is, I can't remove this software without trashing my RAID volume (I'm striped over twin 120 Gb drives).
Here's where it gets weirder: I downloaded the 1.07 firmware update, but the flasher program routinely & immediately blue screens me. The error is in iastor.sys, which is, you guessed it, the Intel Application Accelerator.
Now, I'm sure someone must've gotten this config working, since I see ABS PC selling pre-built rigs with the 2500A on an Asus 875 mobo. Any gurus out there with a more helpful hint than "backup your data, trash the RAID volume, and start from scratch?"
Thanks in advance!
