I am running Win98SE on 2.4GHz P4 (Intel D845GEBV2 chipset), 60GB Maxtor HD, 512 MB RAM. I was replacing a Lite-On CD-RW that began crashing my system when I tried to burn. When I pulled it and installed the Plextor, my system began booting to the BSOD after going through some of the startup process. My error message is "Exception OE at 0028:C1980C99 in VxD SCSIPort(01)+000007D9. This was called from 0028:C1C323A4 in VxD scsihlp(03) + 00000774." Then things got interesting. My secondary IDE port also has a 16x Lite-On DVD-ROM as the slave. I tried replacing the old 40-wire IDE cable with the 80-wire cable included with the new Plextor drive. Still BSOD. I tried unplugging the Plextor, and I could start up again. I went hunting for drivers, BIOS updates, and advice. Updated the BIOS. Still BSOD when Plextor is connected. Eventually, my system got cranky and started crashing with just the old DVD-ROM connected. I sit here typing on a machine that has had all CD/DVD drives unplugged and disconnected. One other potentially interesting thing. The Plextor software that I installed before my DVD-ROM wigged would sometimes give me an error message about "wnaspi.dll" saying I had version 188.8.131.52 and that could cause problems. Could it be causing the crash? Why would my old DVD-ROM suddenly go wiggy, too? My current plan of attack is to follow the guides here on updating ASPI files and then re-attempt to connect my Px-716A. As far as I can tell, all cables and jumpers are set/connected appropriately, except for possible 40-wire vs. 80-wire cable issues. Any advice anyone can offer would be greatly appreciated. THanks much in advance!
