Wanting to update the firmware for my Sony 710a. So have been looking around for instructions on how to disable DMA which Sony say to do.Gets a bit confusing in Device Manager,as I have two Primary IDE Channels listed and 2 Secondary Channels.Do I go into all -Properties/Advanced settings and change both device settings/transfer mode to Pio only?Then do the opposite after flashing the DVD drive? This seems to be for the whole pc, not just the drive itself, correct? Thanks.

I think just the IDE channel containing the drive being upgraded needs to be set to PIO mode IMHO. :2cents:

Thats what I did for my DVD drive. (Sony DRU800A)

Thanks for replying,bob_doe_nz.Have looked at all 6 entries under IDE......controllers and can't find any mention of any dvd/cd drives. Any more clues? Also can't see any mention of DMA if I look into the drives section in Device Manager.

If its a windows 2000/XP system its under IDE ATA/ATAPI controllers
Its usually the Secondary channel usually that the optical drives on... check with your computers bios.
