UltraDMA EIDE go bye-bye?

[Thermodynamic]

Hi! I have an Asus A7V133 w/1005 bios. I have a SCSI-based system, barring one Western Digital 7200rpm 30gb ATA100 drive. 768mb RAM ensures I don't run out.

When I originally installed Win98SE, I was able to check the DMA box in the HD properties.

Recently, I've been doing video digitizing. It had worked... I have not changed my configuration at all, but one day I started getting an 80% dropped frame rate - before I've never had a dropped-frame-rate problem at all; all frames until now were being captured.

I went back into the HD properties and noticed that the DMA option is no longer available.

I bet the HD is not running at optimal speed, hence the frame drops.

Since I know the checkbox was originally there, but is there no longer, there's a problem.

I have downloaded the latest Promise controller drivers - but that has not helped.

What can I do to get DMA mode re-enabled?

Thanks!

You DID install the latest VIA drivers right? It has an option to enable DMA and enable Turbo in the AGB driver install. Try that out or if you have, reinstall it and see if that helps.

I think he is talking about the Promise raid controller. Via 4in1 will not support this. It is common in these types of controlers for the dma option not to be on the hd drives propertise. Instead look at the controlers propertise. Many have options to support dma for atached drives in this local. I have not used the Promise Raid controller so I can not say for sure but it's worth a look.

In my standard UDMA100 controller tere are no DMA options, this is set during the install of the VIA drivers. so like the above post sais reinstall them and select DMA whne asked.

You still need the VIA IDE driver updated even with the HDD on the RAID controller. The Promise is for RAID configs but the IDE driver is for the HDD itself. Update your VIA 4in1 drivers to 4.32.
