How about a clean install of Windows with the drive connected to the PC? Still cannot run in DMA mode?
When I run Windows XP (I tried WinXP and WinXP SP2) installation from bootable CD, it runs ok, but when installation is complete and OS is starting -> DVD becomes "blind" and doesn't recognize any CD or DVD, also OS hungs up for several minutes. When I switch drive to PIO mode, it begin to function normally. So, DVD doesn't work in UDMA even on clean system.
P.S. during my exmeriments I reinstalled system about 10 times ....
Also, DO NOT install the new via ide accelerator driver!!!!!!!
I tried to install it, installation completed, but nothing changed
....I'm so tired of searching for answer ....
