New to this Forum. Reg key is; HKEY_LOCAL_Machine\System\CurrentControlSet\Control\Class\(4D36E96A-E325-11CE-BFC1-08002BE10318)
Clicking key brings up both IDE Channels listed as-0000, 0001,0002,Properties. Also, while I was able to reset the 6 error failback by deleating MasterIDChecksum and SlaveDataChecksum under under IDE Channel 2 Master/slave and release this system from the locked PIO mode under DMA settings,was able to set DMA Mode 2. The burner supports UDMA66. So thats were I'am at. I also disconnected my zip drive from IDE 2 as slave. Bios is Award V6.0, Revision 1012 dated 7-22-04. I never did check the chipset drivers as it was a new XP Pro install, though headded that way as soon as I post this

Of course. What I did this morning was back to Regedit and deleated MasterIDChecksum. Then to bios and rechecked all and in between trying other config, removed IDE Channel 2 each time I rebooted. Finally was able to obtain UDMA-4
