View Full Version : DMA Troublez

I have recently upgraded to a 10GB Quantum Fireball HDD. It supports UltraDMA 33 but I cannot seem to enable DMA. Even ticking the DMA box in the Device Manager under Disk Drives does not work, when I restart the system for the changes to take effect it is unticked again. My motherboard supports up to DMA 33 transfers so why does it not work. Could it be that I have an older 500MB HDD that only supports Mode 3 as my Primary Slave device. I am currently running a Pentium 2-266MMX with 64MB SDRAM on a Microstar MS6126 motherboard. Any suggestions would be appreciated.

Yeah, as annoying as it is, If you have an older drive, that doesn't support ATA xx connected to the same mobo, your computer goes with the lowest common technology.

Are you sure you can't spare 500mb anyway?

The speed increase IS noticable.

The 500mb drive should only affect devices on the same channel.

Try taking off anything else that is on its channel.

Also, make sure you have installed some new drivers for your motherboard.

Move the 500mb (if you really need it!) to the Secondary IDE, either as master or slave (depends what your CDRom is) and this should allow the change.

My mother board can have both ATA and Non ATA on the same cable and still run the ata drive at full speed.
