I have a drive labeled MRX523252A.II
BIOS recognizes it as MEMOREX 52MAXX 3252AJ
What should I set the PIO mode and ULTRA DMA Mode to in BIOS?
PIO is 0-4
DMA is 0-5 or Disabled
DMA as high as possible.
Set your Bios set to Auto or Auto detect. That is the best seting you can use. Once in Windows go to your device manager and under IDE ATA/ATAPI controllers make sure your DMA is is set to DMA if available.
