Impossible to enable DMA- Tried Everything.

S

Steve

Used a drive from another build with the same Asus P5WD2 Motherboard
and can't get Windows to enable DMA transfer. Am only mentioning that
because when Windows first booted, both of my optical drives were not
listed in Explorer.

In Device Manager>Secondary IDE Channel>Advanced Settings, this is what
it looks like:

Device Type: Auto Detection
Transfer Mode: DMA If Available
Current Transfer Mode: Not Applicable

Why is it reporting "Not Applicable" in both Secondary Channels if I am
able to burn CDs and DVDs?

The CDs are burning at a normal rate but a ~4.37 GB DVD is taking about
40 minutes to burn. I have tried practically everything in the book:

Uninstalled the Drivers
Deleted both burners with the Device Manager
Changed the existing round cable to ribbon
Changed the ribbon back to round cable
Checked the BIOS and both Burners are recognized
BIOS Settings for these drives have the default setting of Auto

Haven't attempted the registry fix yet in HKEY_LOCAL_MACHINE \ SYSTEM \
CurrentControlSet \ Control \ Class \ {4D36E96A-E325-11CEBFC1-
08002BE10318} because the guide was written before WinXP was released
and values are listed differently in the registry.
"MasterIdDataChecksum" is not listed.

"if the troublesome drive is the master, delete the
"MasterIdDataChecksum" named value. Or, if the troublesome drive is the
slave, delete the "SlaveIdDataChecksum" named value. Reboot. The OS
will redetect the device DMA capabilities after reboot.Note that for
many older CD-ROM drives DMA can not be enabled in Windows"

And to add more icing on this Cake; Both drives will not boot from CD -
My boot sequence is listed as: Floppy, CD, DVD. The DVD-R drive is set
as Master and CD-R as Slave. I've been fighting with this DMA issue for
the past two days and rebooted the computer too many times to remember-
Please help, I'm going nutZ.

Hi Steve,

did you install the latest Intel chipset drivers ?

According to the Asus website its using an Intel 955X chipset. Drivers
should be available here:
INF Update
http://downloadfinder.intel.com/scr...xe&agr=N&ProductID=2107&DwnldID=9026&lang=eng
Click to expand...

This update was installed and it is possible to boot from CD but in
the Device Manager>Secondary IDE Channel>Advanced Settings, nothing has
changed. Current Transfer Mode is still "Not Applicable".

I disconnected the CD-R and am only using one burner.
Intel Matrix Storage Manager:
http://downloadfinder.intel.com/scr...xe&agr=N&ProductID=2107&DwnldID=9029&lang=eng

This would not install, the reason was: "Incompatible hardware. This
software is not supported on this chipset"

Hi Steve,

I've had a similar problem, I have made this to help people along :




Most people have problems burning CD's, when DMA in on, however a few
of us
burns fine with DMA on, however we experience, that the computer has a
mind of
it's own, at switches to PIO mode apparently on it's own.

I've got some good news and I have got some bad news for you.

First the bad I don't know why this happens, nor do I have a
permanent fix
for you!

The good I do have a fix, that sets your Plextor to DMA mode in
less than
4 seconds, if you follow this instruction.

I had an Asus K7M board, I had The Plextor 12/10/32a as primary on the
secondary
channel, and a CD as slave on the secondary channel. On this setup I
couldn't
run both as DMA, the system would freeze during operation, so the
Plextor was
DMA and the CD was PIO. A few days ago I upgraded to MSI K7T PRO2-a,
and on this
system both the Plextor and Cd will run DMA simultanusly.

Unfortunately on both systems the Plextor would get reset to PIO on
it's own -
usually after 'sleep' mode, some kind soul send me a workaround.

You need to find this path in your registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}
In my present setup there is 7 keys under this path:
0000
0001
0002
0003
0004
0005
Properties

In my old setup the information I needed was in Key: 0002, but when
the
workaround didn't work with my new MSI board, then I sought the reason
why, and
found, that key 0002 and 0005 (presumably installed with the new
motherboard),
had the same information, and that the new motherboard takes it's
information
from key 0005. So if this doesn't work on the default key 0002, look
into one of
the other keys, and see if the information is there too, then maybe
the system
gets the information from there - You will then have to change the
line:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002]
to the key with the information in, which on my system is:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0005]

The information is (you can copy it, and save as DMA_ON.reg if you
want to):

Windows Registry Editor Version 5.00

"SlaveDeviceTimingModeAllowed"=dword:ffffffff
"SlaveIdDataCheckSum"=dword:00009186
"UserMasterDeviceTimingModeAllowed"=dword:ffffffff
"UserSlaveDeviceTimingModeAllowed"=dword:ffffffff


------

The settings for:
"MasterDeviceTimingMode"
"MasterDeviceTimingModeAllowed"
"UserMasterDeviceTimingModeAllowed"
are different for UDMA, DMA and PIO mode.

If you set it like above you will get DMA on both channels, if your Cd
on the
secondary channel can run UDMA, then change the key:
"SlaveDeviceTimingMode"=dword:00008010
which is UDMA.

You could also export the Key above, and just make the necessary
changes to
"MasterDeviceTimingMode"
"MasterDeviceTimingModeAllowed"
"UserMasterDeviceTimingModeAllowed"
and leave the slave at it's present settings, then save it as a REG
file.

Once you have done this, then run the REG file, it will ask you
whether you want
to add the information to the registry, when you answer YES, you will
get a
confirmation, that the information has been added to the registry, and
then the
Plextor is in DMA mode again .... until next time it decides to go
into PIO
mode. I have a copy of DMA_ON.reg on my desktop, and I use it if the
Plextor is
in PIO mode, the change happens 'on the fly', no need to reboot.

Sorry I didn't have a permanent solution, hope this makes the pain
easier to
live with, until someone comes with a BIOS upgrade, IDE Driver or
system patch,
which permanently solves the problem.

I DO know that once Windows 2000 decides that the Plextor is only PIO
mode
capable, then nothing 'normal' will pursuade it otherwise. But if it's
a fault
on Windows side, or that the Plextor gives wrong information to
Windows about it
self, or the IDE drivers reports the wrong settings - I don't know.

I've noticed, that upgrades of the Plextor Bios and IDE drivers cause
a new scan
of hardware, and the Plextor once again becomes DMA, but once it's set
to PIO
with these drivers, then Windows remember this setting and won't let
you change
it normally.

So even downgrading the BIOS won't reset it to DMA, if Windows once
has decided
that with this BIOS it's only PIO capable, or with these drivers it's
only PIO
capable, then 'it's forever'!!

changing more to DMA can occur automatically in Windows if there are IO
problems talking to the disc drive (not IO issues with the disc). E.G. when
there is a shoddy cable.

Try a different cable.

Check your BIOS settings.

Hi Steve,

is there a BIOS option to enable AHCI mode for the southbridge. This read in
the accompanied readme on Intels website.
And trying changing the cables.

Greetings,

Try the CD-R on cable select and the DVDRW as master. I have run into a
similar problem before

You do have the 80 wire cables installed ?

I installed the burners using the ribbon which was supplied by Asus in
the P5WD2 box and purchased a round cable from Compusa for the Optical
Drives which also has 40 pins/wires.

Could the 40 pinned cable be causing all these problems with DMA?

Thanks for replying -

Just tried this suggestion and the Current Transfer Mode still is
listed as "Not Applicable" in the Secondary IDE Channel.

There is an option in the Main Window > IDE Configuration > Configure
SATA As Selected -

[Standard IDE] <--- which is the Default Setting
AHCI
RAID

This is the only place that "AHCI" is mentioned. Did a search at Google
and found out that if this option was enabled, I would have to
reinstall Windows to gain any benefits from this change.
Are all these problems DMA problems with my CD & DVD Burners related to
the 200GB Seagate SATA Hard Drive that I am running?


Thanks once again -

Not Applicable is supposed to mean there is NO device in that location,
not that it is running in PIO mode. Are you sure that is actually the
channel where the drives are hooked up? Try View - Devices by connection.
