Help get my primary hard disk into DMA MODE!

[Chronic321]

Athlon XP 2200+
Asus A7v333 (Via Kt333) --> Supports up to UDMA 6 (ATA 133)
Maxtor 80 GB hard Drive (Supports ATA 133)
Latest VIA Drivers 4-1 (Although under device manager my Vis Bus master driver is still dated 7/1/01)

I am currently running in PIO mode according to XP home edition device manager. I've been jerking and stuttering in GTA 3, I think it is because my Hard Drive is getting the data too slow off my hard drive. I have the "Run in DMA if Avaliable" option checked under my Primary IDE Channel options, however it says the current transfer mode is PIO even though my BIOS says UDMA 6 or ATA 133. I tried the Via mini port driver but that worsens performance and makes Windows think I am running a SCISI disk. Please tell me what I need to do to enable DMA mode. Thanks, help with GTA would be cool also (I have a TI 4400 for gods sake).,

I had this same problem with one of my drives. It turned out to be the cable that was the culprit. Probably yanking it out too many times. I have heard that if Windows finds too many problems with the current speed, it will default down until it finds a stable speed. Once it lowers the dma it will never go up again. Changing the dma anywhere in any setup will not cure this problem, only disabling and reinstalling the ide drivers will cure. I too had more problems installing the via 4in1, and eventually just went with the miniport. And yes, my system config says I am running a SCSI, though I'm not.

Anyway, try reseating the cable and reinstalling ide drivers.

Hope this helps.

suggest you uninstall your Primary IDE Channel in device manager, reboot & windows will redetect it hopefully with dma transfers enabled!
