Thank you LLXX!!! 303, hope this helps you I did the same thing as 303... fresh install of 98se on an older machine that (thanks to norton) had to be reloaded. Nero Express 6 worked fine before, then I had all kinds of write problems. I have an ABIT KT7A-RAID w/VIA chipset and loaded (VIA) recommended drivers and busmaster drivers. VIA IDETOOL said DMA was enabled, but didn't even show up on properties for DVDRW/CDRW drive. I ran the setup for the VIA 443 drivers, selected uninstall for everything, rebooted, installed VIA 338 drivers (all except IRQ miniport, 98se has those), rebooted... DMA shows up in properties, is enabled, i b burnin' again! Thank you again LLXX and erpdude8.
