How Do I disable DMA in SafeMode in Win98

[Joony]

Enabling DMA causes the computer to not boot to windows. How do I disbale this DMA in SafeMode?

i don't have win98 installed anymore, but off the top of my head... i think it goes like this...

control panel --> system --> device manager --> properties of ide controller --> advance settings

u should be able to disbale dma in there.

highlite the "my computer" icon..........right click .......click on properties.........click on device manager.......double click disk drives.......this brings up all your hard drives........highlite on the one you want....(c: drive).......right click........click properties.......click settings..........uncheck dma checkbox...........when you close it out ..you will have to reboot..........should work........

edit..........same as above.......diffrent route.......lol..........

 

[Joony]

There is no DMA checkbox.....it seems to be missing.

 

[spanky]

perhaps ur hardware does not support dma?

 

[Joony]

yeah but the DMA checkbox isn't there in safemode! how do I undo checking the DMA box in safemode?

 

[spanky]

have u tried to disable it in the bios?

 

[Joony]

i don't believe there were DMA settings in the bios and to make this worse, this is my friends computer! i'm screwed

in the course to trying to help me troubleshoot a cdrw drive... this is what hp instructed me to do:

Before sending the drive for warranty service, I would like to
troubleshoot the issue with the drive not being able to read CD or DVD
media.

The drive not being able to read media is related to the system trying
to use the direct memory access (DMA) method to communicate with the
drive.

DMA is a technique for transferring data from main memory to a device
(such as a CD-Writer or hard drive) without passing the data through
the central processing unit (CPU). While the data transfer takes place
via the DMA controller and DMA process, the CPU is available for other
functions. Computers with DMA channels can transfer data to and from
devices more quickly than computers without DMA channels. However, not
all hardware or software supports the use of DMA.

Use the steps below to disable DMA. In some cases it may also be
necessary to disable DMA on the CD-ROM drive to resolve the issue.

1. Click Start, Settings, then Control Panel.
2. Double-click the System icon to open the System Properties window.
3. Click the Hardware tab and click the Device Manage button.
4. Double-click IDE ATA/ATAPI Controller.
5. Double-click the controller the CD-Writer is attached to (normally
the Secondary IDE Channel).
6. Click the Advanced Settings tab, click PIO Only in the Transfer
Mode box.
7. Click OK, close the Computer Management window and reboot the
computer.
8. After restarting go back into the Device Manager and verify that
the DMA mode is disabled.

If the DMA mode remains enabled after rebooting, it might be necessary
to configure the HP CD-Writer as the master device on the secondary
controller.

1. Connect the HP CD-Writer Plus Drive to the Secondary IDE
controller using the cable that is included with the drive, and
set it to master.
2. If using another CD-ROM drive, set it to slave.
3. Be sure the drives are jumpered properly.
4. Go into the system BIOS and Advanced settings.
5. Try changing the IDE configuration.
6. Change the Secondary master definition from Auto to CD-ROM. This
should allow defining the mode.
7. Change the mode from Fast PIO mode 3 with bus mastering to Fast
PIO mode 3 without bus mastering.
8. Save the settings and restart the computer. DMA should now be
disabled for the HP CD-Writer.

If the issue persists, use the following drive light check to determine
if the drive is defective or if there is an issue with the cable or
driver:

1. Turn off the computer.
2. Open the case and disconnect the data cable from the back of the
HP CD-Writer Plus drive.
3. Power on the computer.
4. Insert one of the discs that you have been unable to read.
* If the media indicator light flashes and then is on solid,
there appears to be an issue with the data cable, IDE
Controller, drivers, or Windows configuration.
* If the media indicator light flashes and then goes out, please
get back to me with the results.

Note: Be sure to test more than one disc, because a bad disc can
also cause the drive light to go out.

It is important to us that we answer your question. If you need
further assistance, please reply to this message, we will be happy to
help you.

hope this might be remotely helpful.

which device did you enable dma on?
suggest you boot into safe mode & remove the offending device then reboot normally.
windows will redetect the device & enunerate it accordingly!

First post in a long time.........

This problem is one that I had to figure out for similar reasons, but was a customer computer and reloading wasn't an option.

Only way I found to fix it was to edit the registry. Wish I had Win98 still loaded so I could just point you to the right key.

Further to above, HP is correct with:

1. Click Start, Settings, then Control Panel.
2. Double-click the System icon to open the System Properties window.
3. Click the Hardware tab and click the Device Manage button.
4. Double-click IDE ATA/ATAPI Controller.

Don't click on disk drives, since it's not there, but it is actually under the IDE ATA/ATAPI Controller tab.

Good luck.

Michael.

this guy is using win98 not xp or win2k

As far as I can remember, Win 98 had a similar item, maybe called Disk Drive Controllers?

I'm sure it was something completely seperate from Disk Drives, but I could be wrong.

It rings a bell, since I was using the Via 4 in 1 drivers at the time, which enabled DMA settings.

You could also try disabling it in BIOS, as HP suggested.
