A hack, anyone, to turn on dma ?

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

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
may be the one shown above. Check to be sure it hasn't changed now due
to your Device Manager activity. Post that full Registry key. Here is
mine for my CD-R/W, which does have DMA checked. "DMACurrentlyUsed"
sounds to be most relevant...

Can it be similar in Win98? I see on glee's instructions you went the

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?
It reinstalls on reboot

Here is my key. DMA is currently "off"

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...

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.

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

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.

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/Dr..._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/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
ones.

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?
I have no other place to point to ..... there are no
non-windows drivers.

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?
