I tried to reboot after uninstalling the driver onmy
dvd burner but it stays in pio mode, Is it possible my default mode is incorrect, I tried every which way but it stays in pio mode any help would be greatly appreciated.
I have copied instructions from Sniptools.com, whch worked perfectly for me.
I only had to delete the registry key for the Secondary master on the IDE channel, where my DVD burner was (002)
All due to XP not being able to read a disc or discs, with an override being introduced to the registry to prevent a crash - but disabling DMA in the process!!
If you have Nero use Info Tool to check on your IDE configuration
CD-ROM and DVD-ROM drives can revert to using PIO mode, despite being set to use "DMA if Available." Here's how to make Windows XP redetect the DMA capabilities of the drives.
This behaviour occurs with the following conditions:
Windows XP is the operating system
A CD-ROM or DVD-ROM drive, which is known to support DMA mode now works only in PIO mode.
The drive controller is set to use "DMA if available" but reports to be only in PIO mode.
Following is the mechanism that has worked for me, please try it at your own risk, it involves hacking the registry:
Open RegEdit
Find the following KEY:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\000x
The last four digits will be 0000, 0001, 0002, 0003, and so on.
Under each key, delete all occurences of the following values:
MasterIdDataChecksum
SlaveIdDataChecksum
Reboot the computer. Windows will now redetect DMA settings.
Trala!
