A hack, anyone, to turn on dma ?

put finger to keyboard and composed:

| I have an AMD K6-2 450MHz. The Ricoh reads at 6X in P-CAV mode.

Well, that's about the min. for reliable CDR/W. You must be having some
difficulties by now with the new inks and disks..?

I don't use it much anymore. Instead I have an LG DVD writer in my
Athlon XP box. The Ricoh burns Verbatim 1X-16x blanks but has trouble
with TDK 52X CD-Rs.

BTW, if you suspect your drive is burning slowly due to a particular
brand of disc, I think this utility may provide an answer. It analyses
your drive's firmware and reports the hard coded write speeds for
supported media:

http://ala42.cdfreaks.com/MCSE/

You can also use it to patch new media types and speeds into your
existing firmware.

| I used version 0.84 beta of CD Speed for my CPU utilisation and

| the Ricoh's burst rate in both DMA and PIO modes, and a burst rate of
| 1MB/s (1158KB/s) for the 10X DVD-ROM in DMA mode.

| This is what I get with a Drive Check:

Got a 404 on the MP6200A_DriveCheck.txt link
It should be:
http://www.users.on.net/~fzabkar/MP6...DriveCheck.txt

Sorry.

Oh so its only 6X??? oh wow...

Yeah, it's as old as Methusalah but it still works (it cost me about
AU$460). However, I'm a little annoyed that its DMA capability appears
to have been an unfinished project.

| Version 1.02 of Info Tool produced these results:
| http://www.users.on.net/~fzabkar/MP6200A/

Strange, 0 read speed, no read-out, the drive isn't being recognized
properly... see a couple of differences in our drivers, esdi-506.pdr, loaded
system files, etc...

1.03.3 Info Tool read-out for my Samsung drive has been sent to you for
comparison... meb-samsung-InfoTool.zip

Got it.

You might be getting a residual from your manual flash change or your
present driver configuration... though I have noted those same issues when a
drive is about to flake out..

FWIW, here is a Ricoh utility to change transfer modes between UDMA
and MW-DMA:
http://ext.ricoh.co.jp/cd-r/exe/RDTMC.exe

It doesn't see my drive, though.

| What I don't understand about the CPU utilization result in CD Speed
| is that during a file copy test with Explorer, CpuIdle hardly budged
| from a figure of ~95% idle. Furthermore, the same test with my 10X
| DVD-ROM drive (at 2.2MB/s) resulted in 85% CPU idle time in DMA mode
| and 60% idle in PIO mode. With the CPU sitting at 98% when completely
| idle, this equates to 13% busy in DMA mode and 38% busy in PIO mode, a
| difference of 1:3. This ratio is consistent with that observed with CD
| Speed:
|
| 1X 2X 4X 8X Drive speed for DVD-ROM
| --------------
| 1 2 5 10 % CPU utilisation in DMA mode
| 3 7 14 29 % CPU utilisation in PIO mode
|

Might want to compare the drivers - yours verses mine, and re-flash the
Ricoh with the authorized flash version for comparison.
Something is wacked here, but so far its eluding me... let me mual over your
drivers and info for a bit...

Did notice that 6X CDROMs are listed as unsupported in Nero's CFG and it
contains no obvious Ricoh entries.

CD Speed's results for my Ricoh make some kind of sense at 1X and 2X
speeds (CPU utilisation doubles when reading at 2X), but the numbers
are wacky at 4X and 8X, possibly because the drive doesn't support
these speed strategies, only 1X, 2X, and 6X. I don't want to risk
another flash, though ...

Saw that, which is why I decided to download for a look-see.

Yeah, I'm not convinced the DMA hack actually did much for the drive
anyway..

Comparing the two (DMA on and off files) it seems the drive wasn't properly
recognized when DMA was supposedly on when comparing the files you posted.
Drive Information is not *seen* on the RICOH MP6200A when DMA is ON
according to your posted files...

Hmm, not a good sign, though it may be too old for the tool or not designed
for it {obviously}..

I don't blame you on the flash aspect, it IS an old drive...
Now that my brain is keyed to 6X it makes sense that the CPU was 100% at
8X, the speed [attempted data transfer] was just too great for the drive to
handle.. and 4X is darn close to actually being too much..

PER PRIOR POSTED:
-----QUOTE
However, the CPU utilization numbers were consistently different,
although not by much. The following tables represent two sets of five
trials.

DMA off
---------------------------
Speed CPU utilisation %
---------------------------
1X 9 9 9 8 9
2X 16 16 16 16 16
4X 94 94 95 93 92
8X 100 100 100 100 100
---------------------------

DMA on
---------------------------
Speed CPU utilisation %
---------------------------
1X 8 8 7 7 7
2X 12 14 13 14 13
4X 92 93 95 93 92
8X 100 100 100 100 100
---------------------------
---------END QUOTE

So again, it doesn't appear the hack did much, there should have been a
much greater gain - less CPU usage.

Uh-huh. You appear to have "substitute connections", instead. But we are
both unchecked for that. What are you saying about your spell checker?
The Brazilian translation is awful.
Those settings are scarey to fool with. But, if everything is showing up
for you in Device Manager, looks like you've got both your IDE Channels
enabled.
Yep.

That shouldn't have a bearing on the DMA issue. Sounds like all your
settings are much like mine. I see nothing in this to explain your
peculiar circumstance with that DVD.
Probably a samsung/asus bug. But it DOES work as master under
linux. So probably best just to leave it as slave. Works under both OS
that way.

OK. Just as I guessed.

Just checking one last time. OK, fine.

Sounds like a good plan to me. You did well to persist & find that

I never had a tape drive on this machine. IIRC, I once tried MS Backup
which I have since uninstalled but I never bothered to clean up DM.

According to this URL ...

http://www.hastec.nl/support/onstrea...-art-1002.html

.... MS Backup is the likely reason for the presence of those files.

Anyway, after deleting the following keys ...

HKEY_LOCAL_MACHINE\Enum\TAPECONTROLLER\TAPEDETECTI ON\000n

.... and renaming the DRVWCDB.vxd, DRVWQ117.vxd, and DRVWPPQT.vxd files
in the C:\WIN98SES\SYSTEM\IOSUBSYS directory, and the PnpWppt.INF file
in the INF directory, the TAPE entries disappeared from DM.

Yeah, that would have done it...

Anyway, kinda drifting off the mark...

ASPI looks okay I suppose, so does esdi_506.pdr though you could have a
newer version via a few official or unofficial updates. Did you miss the
Nero update for version 5? Need it? nero551056.exe - 19,171KB

Still not happy that when DMA is enabled the drive _isn't_ being recognized
at all, but when DMA disabled *it is*...

And I missed:
Write Speed (Max.) : 2 X.
so the drive tests were REALLY pushing the limits of the drive.
