i just purchased a 812S and flashed it to 832S before i did anything. When i looked in device manager (windows 98) i noticed that there was no option to tick DMA. I know it is possible as my creative dvd-rom has an option to tick DMA. Does this drive support DMA or have i done something wrong
Your DVDRW drive supports DMA up to UDMA mode 2.
Uninstall the IDE-channel drive is connected to. Restart computer and hopefully your Win98 will install new drivers with DMA support. (I assume drive is on secondary channel.)

Thanks for the reply. I’ve set it up as slave on the Primary IDE as this is what my previous burner was… does this matter?
Also i tried ripping an audio cd and only got a max speed of 2x is this due to the lack of DMA?
Yes, DMA must be on.
Have you uninstalled Sec. IDE-channel and restarted compu?
- In the Device Manager, expand the IDE ATA/ATAPI controllers entry,
either by double-clicking IDE ATA/ATAPI controllers or by clicking on
the + next to it.
Select the appropriate IDE channel (Secondary). To get to the IDE
Channel Properties window, either right-click the channel and then
click Properties, or select the channel and click Action -> uninstall
in the menubar.
- Restart. Let windows find the appropriate drivers on next start.

Q: Why has the DMA box disappeared in the hard disk Device Manager under
A: The DMA box can only be used with the standard Microsoft driver. When a third
party driver is installed (such as the AMD EIDE Driver), the DMA box will no
longer appear. However, the driver is programmed to use all devices in their
most optimal configuration. Therefore, if DMA is available for that particular
device, the driver will use it.
does this mean i can safely assume my liteon drive is using DMA cause it supports it?
everything is working fine now thanks for ur help!!!
Could you post this part of the nero infotool output of your now working win98 config:
Adapter 2 --------- Description : Secondary IDE Channel Driver Description : ESDI_506.pdr Company : Microsoft Corporation Version : 4.10.2222 Description : ESDI_506 Virtual Device (Version 4.0) Attached Devices Description : LITE-ON DVDRW SOHW-812S Type : CD-Rom Drive
In this thread http://club.cdfreaks.com/showthread.php?t=111871&page=2 someone has problems with win98 and it would be fine to see if he has the right driver. “Virtual device” sounds a bit strange to me.
This what you’re after?

The only thing I find wierd is that it could not separate out the devices into their respective IDE channels ie primary and secondary.
It just says ‘unknown’
LOL, I was offline for several hours having some nice drinks, and yes, right on time, that was what I was looking for (at least for this problem ).
