A hack, anyone, to turn on dma ?

[Shadow]

My samsung sh-182f DVD writer has become horribly slow,
records at 1X max, even with 16X disks.
I cannot turn DMA on in the hardware manager.
Even my floppy drive has DMA ........
Must be a way. 6 hours hacking and nothing so far.
TIA
Apparently there is a registry/system entry that does not
allow DMA on a drive, but cannot find it. Neither on PC or on Google.
The drive had DMA a month ago, last time I checked.

What processor/motherboard/chipset?

Have you checked the BIOS settings to see if they have changed?
Is UDMA enabled for the IDE channel the drive is on?

What happens when you try to enable DMA in Device Manager?
Are there any problems noted in Device Manager?

If those URLs glee posted don't fix it...

(1) "START button, Run, MSInfo32, Components, Storage"
(2) Bolt "Advanced Information", &
use the Edit menu to post it.
(3) Bolt "History", use the mouse to highlight DVD information,
& use Ctlr-C to copy & post it.
(4) Click, copy & post "Problem Devices" too, if any.

Debug ? OK, here we go:

o 176 a0 ; a0 (a-zero) is for a master drive, use b0 for a slave.
o 172 22 ; 22 is for DMA mode 2, use 21 for DMA mode 1.
o 171 03 ; 03 (zero-3) is to program the hard disk timing.
o 177 ef ; ef is the set feature command for the hard disk.
i 171 ; Reads in the error status; a value is returned.

Got 00 for anything from 21 to 25 in line 2
So the drive accepts up to dma 5
dma 6 returned a 04 error

So my bus-mastering driver has gone bad. But I tried the via
434, 456, and 517 before posting this plea for help.

Any suggestions ?

Suggestions? Sure.

Open Device Manager, select the top entry (Computer icon), and click the Properties
button.
This will display the IRQ settings.
Select Direct Memory Access(DMA) to view devices using DMA Channels.
What DMA Channels are in use?

There are 8 DMA channels but one is used by the DMA controller so 7 are available
for devices.
Tell us what device is using each channel.


Uninstall the Via chipset drivers (4-in-1 driver).
Reboot.
Then restart in Safe Mode.
Open Device Manager, remove all items in the CDROM category, remove all items in the
Hard disk drives category, and remove the VIA Bus Master PCI IDE Controller in the
Hard disk controller category.
Restart in normal mode, let Windows redetect both the primary and secondary IDE
controllers, then reboot and install the Via 4-in-1 drivers.

If that does not help, replace the IDE ribbon cable attached to the DVD drive with a
new one no more than 18" long.
Repeat the above steps if needed.


In looking at the info you posted in reply to PCR, I notice you have viamvsd.vxd and
VIAmraid.mpd installed. Those are Via RAID controller drivers....are you using the
RAID controllers? If not, why are you enabling them and installing drivers?

No idea. Maybe some driver came with the disk. I see nothing
about raid in the bios.

When I enable dma in device manager, it writes this :
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\hdc\0002]
"DevLoader"="*IOS"
"DriverDesc"="Secondary IDE controller (dual fifo)"
"InfPath"="VIAVSD.INF"
"InfSection"="VIAIDE"
"PortDriver"="ESDI_506.pdr"
"ProviderName"="Microsoft"
"DriverDate"="2001\\10\\18"
"IDEDMADRIVE0"=hex:01
"IDEDMADRIVE1"=hex:01
"AutoInsertNotificationDrive0"=hex:01


Does that look ok to you ?

My understanding is that IDE devices connect to a "bus mastering"
controller which accesses system memory directly rather than by using
the motherboard's DMA controller chip. Hence Device Manager will not
show any DMA channels for the hard disc controller.

See http://en.wikipedia.org/wiki/Direct_memory_access

=====================================================================
A DMA transfer essentially copies a block of memory from one device to
another. While the CPU initiates the transfer, it does not execute it.
For so-called "third party" DMA, as is normally used with the ISA bus,
the transfer is performed by a DMA controller which is typically part
of the motherboard chipset. More advanced bus designs such as PCI
typically use bus mastering DMA, where the device takes control of the
bus and performs the transfer itself.

Yes. It shows DMA enabled for both Secondary IDE Channels. I am starting to think
the drive itself is going bad.

According to IBM's Technical Reference manual for the PC AT, the
original AT had two DMA controllers (Intel 8237A-5) which could each
handle four DMA channels. As was the case with its two interrupt
controllers, the output of the first DMA controller was cascaded into
the second DMA controller.

The manual states that "DMA channels 0,1,2, and 3 are used for 8-bit
data transfers, and channels 5,6, and 7 process 16-bit transfers.
Channel 4 is used to cascade channels 0 through 3 to the
microprocessor".

So what you are seeing as "04 Direct memory access controller" in the
DMA resource list under Computer Properties in DM is in fact the
cascaded output of DMA controller #1.

Well, I just verified that. I had a 3.904 Gb backup to do, did
it with Nero, in windows 98SE, and it took 93 minutes.
I then fired up a livecd PClinux and burnt the same project in
10 minutes and 4 seconds. using K3b.
Both times using LG 16x media and programs set to "max speed".
Both programs reported they were burning at 16x

So it has to be a driver problem.

.................................

When you told me to delete drives cds and busmasters and etc
in device manager, in safe mode, when I rebooted back to normal mode
the computer asked me to reinstall a lot of stuff. I always gave
/windows/inf as the source, and it seems happy with that. But so many
VIA names in the drivers I wonder if I really got rid of them.
If I refused to let it install stuff (by pressing cancel) it
just froze.

http://www.google.com/search?hl=en&q=TSSTcorp+CD/DVDW+SH-S182F++dma&start=10&sa=N
Google has about 132 for "TSSTcorp CD/DVDW SH-S182F dma". I haven't
read them all. Here is one...

http://www.dvdplusvideo.com/dvdguide005.html
Enabling Direct Memory Access or "DMA" for faster DVD copying

That article is speaking of WinXP. It says...

"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."

Can it be similar in Win98? I see on glee's instructions you went the
Device manager route to reinstall drivers. I'd think normally that to be
enough. But how tough was it to install that DVD in the first place? Can
you completely uninstall it so that it no longer appears in Device
Manager at all-- then, reinstall it?

That XP article also speaks of a Registry key. In your Win98, that key

I'm just not sure that constitutes a complete un/re-install-- especially
as you point it to C:\Windows\Inf for drivers. I'm speaking of JUST the
DVD-- not all the other stuff. MSInfo, History, for it showed...

TSSTcorp CD/DVDW SH-S182F
Configuração original Tue Jun 24 22:06:37 2008 para Date

I tend to doubt that actually is the date you first installed it. Do you
have a CD with its drivers? Are there instructions anywhere on how to
uninstall it? I might want to completely uninstall & then reinstall it--
maybe unless that involves actually unplugging it. That might be a
little too much trouble.

Why did you point it to C:\Windows\Inf for drivers? Where did you point
it the very first time when you originally installed it?

That looks like the big difference between yours & mine. Did you try

R-Clk DMACurrentlyUsed, Modify, Delete key, type "01".

But this probably is the eqivalent of checking DMA in Device Manager-- &
probably it will not work. I'm still thinking. Maybe I'll try Google
again.

I find it hard to accept that turning off the DMA setting in Device
Manager is the root cause of a 9x performance difference.

Does your drive/controller/driver have problems reading as well?

FWIW, here is an IDEtool that you might like to try:
http://ftp.tfvs.tp.edu.tw/Windows/Drivers/Bus Master/VIA_ide_3012/IDETOOL/

IDETOOL is described as "Via Technologies drive enhancement software".
It may not support your particular chipset, though.

One other approach may be to read the values of the actual PCI
registers that determine whether DMA is enabled or disabled.

I use a program by H. Oda called Wpcredit:
http://www2.tky.3web.ne.jp/~nrklv/soft/wpcre14.exe

Select Edit -> Device and click your IDE Controller. I believe its
Function number should be 1, but I'm not sure of its device number
(could be 17). If your VT8237 southbridge chip is anything like
earlier VIA chips, then offsets 50-53 will contain the UDMA/PIO
settings for the four primary/secondary master/slave IDE devices.

If you post the values of those bytes, then we could possibly make
sense of them for you. For example, here is an excerpt from a VIA
VT8231 datasheet:

Offset 53-50 - UltraDMA Extended Timing Control ..... RW

bit function
--- ----------------------------------------------------------
31 Pri Drive 0 UltraDMA-Mode Enable Method

0 Enable by using “Set Feature” command.......... default
1 Enable by setting bit-30 of this register

30 Pri Drive 0 UltraDMA-Mode Enable

0 Disable........................................ default
1 Enable UltraDMA-Mode Operation

29 Pri Drive 0 Transfer Mode

0 DMA or PIO Mode ............................... default
1 UltraDMA Mode

If your solution requires turning on any of the above bits, then there
is a program called Wpcrset that can do it for you automatically at
every bootup. In fact I'm using it to tweak the memory settings in my
SiS chipset. I get about a 10% improvement in my RAM benchmarks.

Here are datasheets for two older (?) VIA southbridges:
http://www.datasheetarchive.com/pdf/3640621.pdf (VT8231)
http://www.datasheetarchive.com/pdf/3640622.pdf (VT8235M)

I've built computers for over 14 years (mine only). No
trouble. But the DVDBurner has no drivers, it uses the windows native

Using page 106 of the VT8235M datasheet as a guide, it seems to me
that byte 0x53 represents the "UltraDMA Extended Timing Control"
register for the primary master, 0x52 is for the primary slave, 0x51
is secondary master, and 0x50 is secondary slave.

Decoding the value of register 0x53, we have ...

0xF1 = 11110001b

AFAICT, this means that UDMA mode is being set by this register rather
than by the ATA Set Features command, UDMA is enabled, Pri Drive 0
Transfer Mode is UltraDMA Mode, an 80-pin cable is being used, and the
Pri Drive 0 Cycle Time is 3T (= 22.5ns).

Doing the same for register 0x52 (00010111b) suggests that there is no
primary slave, the Pri Drive 1 Cycle Time is 9T (=default), and the
cable is 80-pin.

The value of register 0x51 (11100110b) is telling us that UDMA mode is
being set by this register, UDMA is enabled, Sec Drive 0 Transfer Mode
is UltraDMA Mode, a 40-pin cable is being used, and the Sec Drive 0
Cycle Time is 8T (= 60ns).

Register 0x50 (00000111b) suggests that there is no secondary slave,
the Sec Drive 1 Cycle Time is 9T (=default), and the cable is 40-pin.

Maybe you could speed up your optical drive by experimenting with the
Cycle Time bits in register 0x51? Or try using an 80-pin cable?
