You are courageous, Shadow, to mess with the fix you came up with that

worked. I've been telling everyone you were fully content!

 

I wonder what your settings are for the following in Device Manager,

viewing devices "by connection". To get the Properties of some, you have

to select them & click the Properties button-- D-Clkng won't work. Here

are mine...

 

PCI Bus

VIA Bus Master PCI IDE Controller

Primary IDE Controller

Generic IDE DISK Type01

Generic IDE DISK Type02

Secondary IDE Controller

IDE-CD R/RW 4x4x24

 

The Settings tab of the PCI Bus allows "Device enumeration" to "Use

Hardware" or "Use BIOS". Mine is bolted to use hardware. There also is a

checkbox to "Override Bridges", which is unchecked for me. Here is the

blurb for those...

 

"You can use either hardware or BIOS to configure devices connected to

the PCI bus. Click Use Hardware for faster performance with fewer

problems. Click Use BIOS if one or more devices are not working properly

when Use Hardware is selected. Clicking Use BIOS can cause Windows or a

device to stop responding."

 

"Select (Override Bridges) box to disregard the BIOS settings for the

PCI bridge."

 

The Settings tab of the VIA Master PCI IDE Controller actually allows

turning off IDE channels. Mine is set to "default". Some of the other

choices are scarey!

 

The Primary & Secondary IDE Controller have no Settings.

 

The Generic IDE DISK Type01 is checked for DMA. Int 13 Unit is checked &

shadowed. It is the same for Type02.

 

The Settings tab of the IDE-CD R/RW 4x4x24 is checked for Disconnect,

Auto Insert Notification & DMA.

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

 

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

interface burst rate tests. Version 1.01.3 produced a result of 0 for

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:

http://www.users.on.net/~fzabkar/MP6200A_DriveCheck.txt

 

Version 1.02 of Info Tool produced these results:

http://www.users.on.net/~fzabkar/MP6200A/

 

In DMA mode, Info Tool hung while interrogating the Ricoh. I was able

to regain control of the program by opening or closing the tray, but

the R/W features were not detected.

 

What I don't understand about the CPU utilisation 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

 

BTW, CpuIdle was not enabled during CD Speed's tests.

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.

 

http://www.ricoh.com/drive/asia/support/faq/mp6200/pc_a.html

MP6200A(ATAPI model); Bus master driver.

.. In some cases the Bus Master device driver does not support the CD-RW

drive. In this case, it is recommended to change to a Standard IDE driver or

update the driver for your specific Bus Master chipset. For details, contact

your PC manufacturer.

 

Application information

.. Problems may occur if memory resident programs like anti-virus software

are installed. This may conflict with the writing software. Please uninstall

the anti-virus program before writing to the CD. If this is not possible,

deactivate the anti-virus while writing.

.. Errors may occur with Task-scheduler running in the background. This is a

utility program installed by Windows 98 Plus. To avoid this, disable the

program or change the scheduled auto-running time.

.. Real-Player (version 4.0 or over) may cause errors while recording due to

conflicts with the writing software. Uninstall this program before writing

to the CD.

I tried those settings before. Don't seem to be related to the

Yes, I do that, thanks. Someone else posted it long ago. That is faster

to do than "Control Panel, System, Device Manager tab", but not

necessarily easier to write.

To get the blurb on "substitute connections" (if any), R-Clk its

checkbox & click "What's This". Then, you may R-Clk the blurb to copy

it. However, it sounds to be just other words for what I've got--

Override Bridges.

 

Since neither of our overrides is checked-- I guess that won't explain

why you must set your DVD to be a slave for DMA & I may let mine remain

a master (which I can only presume it is until I open that box again

some day).

 

Under your Secondary IDE Controller there is JUST the DVD listed, like

mine shows just that CD-R/W?

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.

Uh-huh. Could be these controllers can be made to disappear by fooling

with the IDE channels. I wouldn't want to ever try! Glad you survived

it!

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.

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/MediaCodeSpeedEdit.zip

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

 

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

existing firmware.

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.

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 ...

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...

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.

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.

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/onstream/support/knowledge/kb-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\TAPEDETECTION\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.
