Can't enable DMA
(Click here to view the original thread with full colors/images)
Posted by: BustaCap
In device manager if I select IDE ATA/ATAPI controllers, then primary IDE channel/properties, I don't have the Advanced settings tab that would allow me to turn on DMA. My HD is running on the slow side and I think this may be the problem. The pic below shows a screen shot with the missing tab and also the location info which doesn't look right either:

Here's a link that might help you out.

I had already tried that site, but they just tell you to change it using the "advanced tab" which is the tab I don't have

I'm slightly wary of advising you to install SP2, but it is supposed to cure this particular ill.
I'm assuming your running Win 2K.

oops, forgot to mention my setup:
WinXP Pro
Case: Cooler Master ATC-201
Mobo: Gigabyte GA-8IHXP
CPU: P4 2.4B 533 FSB
Video: Abit Sirulo Geforce4 4600
Sound: Soundblaster Audigy XGamer
Speakers: Klipsch Promedia 5.1
Hard Drive: Western Digital 120GB "Special Edition" 8MB Cache
Memory: 512MB Kingston 1066 RDRAM
CD-RW: TDK VeloCD 40X/12X/48X
PSU: PC Power and Cooling 400W Silencer Soundproofed
Monitor: 24" Widescreen Sony GDM-FW900
I'm wondering if the fact that the my mobo has a Promise controller card has anything to do with it. Although I thought the controller card was only for the RAID function on IDE 3 and 4...
Also, someone else told me this:
 Quote:
When "Intel application accelerator (Intel Application Accelerator)" and "Intel UltraATA Storage Driver" are introduced, the item of DMA is not on a device manager.
In this case, it is introduced when a hard disk controller driver is installed. Please start each utility of "Intel Application Accelerator" and "Intel UltraATA Storage Driver", and set up DMA.

but I have no idea what that means

Check the CD that came with your motherboard for an updated driver.

It's the Intel Application Accelerator. It replaces the device manager control with its own application. Using that software it looks like I am running with DMA on...
but what prompted me to look in the first place is my abysmal scores in Sandra for my HD which is supposed to be a pretty fast HD (Western Digital 120GB "Special Edition" 8MB Cache).

22,783 seems crazy low. And a 12ms average access time is high.

Is it a 5400 RPM drive?

7200

Well, when I look at the specs for that drive, there doesn't seem to be much at all, if anything abnormal about your seek time.
Posted by: BustaCap
12ms seems like a large seek time to me (compared to todays current crop of HD's).
Posted by: Gunslinger
The specs for that drive disagree with you.
For a drive that has an average seek time of 8.9 ms, a 3.1 ms increase on that average at any given time is not at all abnormal.

Who knows, though. That's just what I'm thinking.

Have you tried to re-install Intel Application Accelerator?
Also have you tried enabling it in the bios?
Posted by: BustaCap
DMA is enabled in the bios. I will try reinstalling the intel accelerator.

Here is something pertaining to your problem, only problem is you have no advance settings for DMA.
