whoops forgot to update this.
I managed to get a hold of someone by the name of [google translated]Yoshiken Sakamoto[end] who answered the email from the Microstaff website and was able to provide me the driver/software I was looking for. it was a little rough but I believe he agreed to allow this to be on the internet free and unsupported. So I uploaded it to Archive.

edit: whoa, hold on! I barely even put in why any of this happened. so why did I[should you] care? This allows you to put roughly 9.4gb[4.7 per side] of data on a storage disc. Most of my DOS systems can be backed up on a single side of a double sided disc without compression. On top of that, if you have an optical drive on your modern computer it can read and write to DVD RAM discs formatted FAT32.

The double sided caddy feels like flippies to me too.

Hiho -sry to revive this old topic. I have a SCSI DVD RAM drive and i can't get these drivers to work. I successfully used the formatting tool that came with this driver pack to format the dvd, but i have no clue what files to load / use and how to write files on the disk.

Could you tell me how and give appropriate config.sys and autoexec.bat lines?
Thank you 😀

I tried this driver a couple of month ago and have seen some success.
My drive is an IDE ATAPI device "MATSHITA DVD-RAM SW-9576-C", on Secondary Master (thus device #2. Use MASCAN.EXE to know your device id.)

Here's excerpt from my CONFIG.SYS. Without -L+ option no drive letter for DVD-RAM appeared.

1DEVICE=C:\OLS\DRV\JEMMEX.EXE X=TEST I=TEST
2DEVICEHIGH=C:\OLS\DRV\ATAPIDV.EXE
3DEVICEHIGH=C:\OLS\DRV\DVDHOOK.EXE
4DEVICEHIGH=C:\OLS\DRV\MSDRVR.SYS -O2K -i2:L+,D1,VAR
5DEVICE=C:\OLS\BIN\JLOAD.EXE C:\OLS\BIN\XCDROM32.DLL /D:XCDROM

ATAPIDV.EXE: ASPI Manager for IDE devices. Should be unneeded if you use SCSI HBA.
DVDHOOK.EXE: enables DVD-RAM support.
MSDRVR.SYS: adds support for FAT32, etc.
XCDROM32.DLL: CD-ROM device driver. Not from MOHelper32 package but from JEMM.

And This from my AUTOEXEC.BAT.
Use Q: to access for media not DVD-RAMs.

1LH SHSUCDX /D:XCDROM,Q

Hope this helps.

I think I found why "-L+" option is required.
In their ASPI Manager implementation, the DVD-RAM drive has two logical unit, i.e. CD-ROM and MO.
Here's "MASCAN -L" output, with a DVD-RAM medium inserted.
