DMA enabled but NO UDMA access for DVD burner

[Rodger Ramsey]

Problem
Pioneer 110D (16x DVD burner FW 1.39 - latest) will only burn at 8x due to
IDE controller transfer mode of multi-word DMA mode 2 being max speed
setting, according to Device Manager, despite having the burner rated as
UDMA-4 compatible. Tried using quality blanks approved by the manufacturer.
I suspect it is a hardware/software/os interaction issue.

System
P4 3.2, 2Gb PC 3200 Kingston RAM, Radeon 9600 256Mb (8.221.0.0 driver -
latest)
Award Bios v6.00PG (F10 update - latest) Auto detect drives, DMA/transfer
rate setting for IDE not available, i.e. not required; assume auto set to
UDMA
120Gb SATA Master remapped to IDE 1
160GB SATA Slave remapped to IDE 1
200GB SATA on SiliconImage SATARaid controller (not setup for RAID) driver
updated
All SATA drives connected with SATA cables
WinXP Pro Sp2
Gigabyte MoBo 8IPE1000P2 (drivers updated)
Intel 82801EB Ultra ATA Storage controller (Driver 6.3.0.1005)
Intel Application Accelerator NOT installed
ATAPY.sys 5.1.2600.2180 (have tried various, this is the SP2 standard)
80-wire cable on Burner (Master set, sole drive on IDE 2) have tried 3
cables
Similar 8x limit with two other 16x LG drives (not installed at present).
Also had a similar problem when I had an ATA-100 IDE HDD on IDE 1 (a while
ago).
Realtec AC97 Audio - updated drivers

Software
Zone Alarm Pro 6.1
Norton System Works 2004 (Anti-virus active)
Nero 6.6.0.16
CloneCD
SP 2 had all updates
ASPI layer working properly
Office 2003
Wp 12
Dragon Naturally Speaking 8.1
Winfast PVR for TV2000 Expert video capture card


Action Taken
UDMA-66 enabled in registry for intel chipset
Have removed and reinstalled devices in Device Manager to clear any
settings.
Have enabled P10 mode, rebooted, and re-enabled DMA in Device Manager to
ensure settings (Note: no errors reported and DMA always enabled by system,
i.e. never had a problem with IDE reverting to P10)
Chipset & MoBo drivers updated - no change. Forced update of atapi.sys to
SP1 version, then to v5.10.2600.2505. No change, so reinstalled Windows
with SP2 slipstreamead. Still no change so reinstalled Mobo and Intel
drivers. Still no change. Before reinstallation I changed registry
settings to include:

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 0]

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 1]

....

dmaEnabled = 1 (DWORD value)

Not that there was errors anyway, but thought I would try above, just in
case. It made no difference.


Comment
The system is generally very stable and the DVDs burned at 8x show no
errors. When I try to burn them at 12 or 16x the max transfer rate of about
12Mb/sec limits the true speed to 8x burning, although the burn quality is
still OK. Transfer rates for the SATA drives (obviously through their own
connections) are consistent with UDMA 5/6 speeds, and not an issue. It's
only IDE 1 & 2 that are speed-limited. Now perhaps I should be happy to
have a stable system and a burner that produces quality burns at 8x, but I
am really keen to find out why UDMA will not be enabled for the DVD burner.
I think all the relevant Services are operating, although some (that appear
to security risks, unnecessary, or resource hogs) are disabled. I based the
selection on info from blackviper.com, theeldergeek.com, and MBSA 1.2 & 2.0.

Any suggestions?

Re: DMA enabled but no UDMA...

Reboot and access the BIOS.
Adjust the drive's properties for DMA and UDMA.

Thanks for the reply, but the BIOS does not have a DMA/UDMA/P10 etc., option
in setup. The first thing I checked was the cables, the second was the
BIOS.

In case I have missed sothing, I will go through the BIOS setup, page by
page:
The Standard CMOS Features are set to autodetect the drives.
The Advanced BIOS Features allow for setting boot order & hyperthreading.
Integrated Periferrals allow for on-chip IDE to be enabled/disabled only (no
mode setting). This page also allows for the remapping of the SATA drives
to the IDE ports.
Power Management features are not relevant, I think.
PnP/PCI configuration is set for Auto PCI IRQ assignment.
PCHealth Status, Frequency/Voltage Control, Language selection, etc., do not
appear relevant.

So what do you think?

Hi;
Should have a sub-tab for its properties when you highlight the DVD drive.

Perhaps I am missing something, but I could find no tab or sub menu or
anything that allowed me to change the DMA mode. I looked in the manual and
could not find anything either. In fact, I downloaded a PDF version of the
manual and did various word searches to see if there was anything that could
help but to no avail. Just in case, I changed several BIOS settings for the
channel the DVD drive is on, but they had no effect.

Is it possible that the Windows driver for the IDE controller (although an
Intel device, it uses WinXP drivers) is conflicting with something?

Is this the only device on the channel? If its shared try making it the only
device and see if there is any difference.

There is a web site here with good info and a script that might help.

Glen,

Thanks for the link. I may have come across it in my googling to solve the
problem. BTW, the burner is the only device on the channel.

I think my original message was edited along the way, but the problem is not
that the IDE channel reverts to P10 mode (usually due to errors) but that I
can only get Multi Word DMA 2 instead of UDMA 2/4.

From what I can gather, the registry is not the problem, and neither is the
device, its firmware or the cables.

I don't have Alcohol or Daemon tools installed (I think they mess with
atapi.sys).

I haven't found anything in the BIOS that helps (maybe it's there, but I
can't see it).

So...I'm not sure.

My Gigabyte MoBo's BIOS has hidden settings accessed by pressing [ctrl] F1
at the right screen. I was able to access these (eventually) and set the
DMA mode for IDE 1 & 2 to AUTO. There was no mention of this in the manual
or on the Gigabyte site. None of their utilities accessed these functions
either. The new setting has given me full UDMA 4 access to the DVD burner
and even improved the transfer rate of the SATA drives - perhaps because
they were remapped through the IDE port(?!).

Thanks for your input guys, it motivated me to keep going to find a
solution.

Re: DMA disabled but...

OUF!!!

[CTRL]+F1

Makes you wonder why the h*ck Gigabytes makes that an hidden setting doesn't
it!

It's a primordial setting and as such should be directly accessible.

I knew there was a way get it done as I fixed that problem once on a
friend's machine with a "Giga" board.

Just couldn't remember the specifics and the manual was at that time of no
help also.

"All's well that ends well".

Thanks for reposting that you fixed the problem, its good to know what the
fault was.
