does anyone know how to change Dma on win xp ???
i went to the propertis of the dvd-rom in system information and there wheren't any dma box to chose.
in win98 i found it but if i change in the win98 does it affect the
win xp ?

10x

Dual-boot 98/XP setup, I assume.

In win98 i found it but if i change in the win98 does it affect the
win xp ?

No.

"Go to" control panel / system / hardware / device manager /
"expand" ide controllers /
"select" " PRI or SEC ide channel / properties / advanced properties........Voila....

I'm not a newbie but my properties for each IDE channel in XP home does NOT have the Advanced tab - just General/Driver/Resources. If I look in the DMAs used I know there are none allocated to IDE devices.

Is this XP home or a function of my MB (Intel D845BG Intel P4/2.0AGHz)?

According to my documentation:
In WindowsXP the DMA option is hidden but is always enabled.

From WindowsXP help files:
DMA is located in the Hardware Resources category in System Information. It displays information about your system's direct memory access (DMA). DMA transfers data between system memory and hardware devices without passing it through the CPU. The Resource column in the details pane displays the DMA channel that is being used by the device, which is listed in the Device column. The Status column displays the status of the device.

If the Status column indicates an error, such as Error, Degraded, Unknown, Pred Fail, Starting, Stopping, or Service, you can try the following troubleshooting solutions:

Use Device Manager to locate and troubleshoot the problem. For more information about Device Manager, see Device Manager.
Contact the device manufacturer to obtain an updated device driver.
Reconfigure the settings in the system BIOS or EFI.
For more information about the Hardware Resources folder, see Hardware Resources.

this is from Microsoft @ http://www.microsoft.com/hwdev/tech/storage/IDE-DMA.asp

For ATA or ATAPI devices that do not work properly in DMA mode.
Compatibility testing at Microsoft has shown that enabling DMA on certain drives could cause data corruption or reduced system stability. There is no way for the user to enable DMA on these devices.

For certain IDE chipsets that cause data corruption.
For ATA or ATAPI devices using chipsets that are known to cause problems running in the DMA mode, Windows will enable PIO by default.
System manufacturers can override this default behavior by implementing the _GTM and _STM methods in the ACPI BIOS. Also, the user can enable DMA using the Device Manager.

For repeated DMA errors.
Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device.
In this case, the user cannot turn on DMA for this device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device.
Windows XP downgrades the Ultra DMA transfer mode after receiving more than six CRC errors. Whenever possible, the operating system will step down one UDMA mode at a time (from UDMA mode 4 to UDMA mode 3, and so on).
If the mini-IDE driver for the device does not support stepping down transfer modes, or if the device is running UDMA mode 0, Windows XP will step down to PIO mode after encountering six or more CRC errors. In this case, a system reboot should restore the original DMA mode settings.
All CRC and timeout errors are logged in the system event log. These types of errors could be caused by improper mounting or improper cabling (for example, 40-pin instead of 80-pin cable). Or such errors could indicate imminent hardware failure, for example, in a hard drive or chipset.

I would look at your bios, drive or the chipset and see if you can find new drivers or work arounds.....
hope this helps .......
