I have recently purchased an Emachines laptop G640.
AMD Athlon processor and AMD M880G chipset.
After installing Windows XP Pro 32 as a dual boot system I cannot get the built in TSST TS-L633C DVD drive to use anything other than PIO mode in Device manager.
The SATA Hard Disk is working fine - using DMA 6
I have tried all the methods described in my google searches.
I have uninstalled the controllers from device manager, edited the registry and run various scripts all to no avail.
The drive runs DMA 5 in Windows 7, so I know it is capable.
Is it just that XP is not compatible with this drive?
Registry listing below:
I have even tried editing the MasterDeviceTimingMode, no success.
Open to any suggestionsor questions
