Got this from https://www.driverguide.com . They seem to have more potentially useful stuff. Have a look .

Thanks, I will give it a try and report back 😀

Any luck?

Thanks for the zip, darry, I just dug out my old drive for a retro config and the driver works in DOS, I got my 3 drive letters. Too bad the internet is now full of fake driver collection websites, some things are hard to find. I found an older version torisan.sys somewhere, but this is the "new" one from 1995.

For future retro maniacs:
Install.exe copies the torisan.sys to a new dir, adds the DEVICE= line to config.sys and mscdex to autoexec.bat so you don't really have to run it, although it creates backup of the original.
The only tricky part where install.exe helped is the parameter: torisan.sys needs a /P parameter with two letters for the position of the drive: device=torisan.sys /D:CD /P:PS where PS stands for primary slave.
