How to uninstall a deeply-embedded driver?

This e-mail seeks detailed instructions on how to uninstall a device driver. I am reasonably competent with PCs, having been using them intensively for over ten years now, but cannot remove a specific driver from my system whatever I do. I need to do this in order to install a driver that should do the same job, but which is quite different (ie I can't do a simple replacement or update)

The driver: is for a Yamaha external synthesizer module that runs from the serial port of my PC. The driver was produced by Yamaha music specifically for that model (MU-10 synthesizer), and is freely available on their WWW site. It serves to pipe the output of my software MIDI sequencer through the COM2 port to the Yamaha MU-10 module using a To Host lead. It is installed via the 'Add New Hardware' setup procedure on my PC

Components: the driver seems to have two active component files, entitled: 1. Yamser.386 2. Yamser.drv

OpSys: Win 95

'Add/Remove Programs' dialogue box: I have tried removing the driver via this Win 95 function, but the driver does not appear there (and never has, as far as I remember)

I conclude: that there is no way of automatically uninstalling the software, and need some form of manual uninstall

Locked into the system: it seems that my PC installs the Yamser driver when it boots up. If I subsequently go to manually delete the Yamser files through Explorer, Win95 informs me (not unreasonably) that I can't delete them because they are being used by Win 95

Uninstall file?: there seems to be no uninstall file or procedure on the supplied Yam MU-10 install disk, and nothing about uninstallation in the README files, so no luck there

Present stage: I really am at a loss as to what to do now, and really need to get that new driver installed

Any suggestions gratefully received
 
Yeah, as pglewis said, check your config.sys and put REM infront of any suspected lines.

Also check out your win.ini file.
 
Or, if you're feeling adventurous, find all the instances of "yamser" in the registry and delete them.
Chnaces are if it's Win95 drivers, they're loaded thru a file called system.dat

You can edit that file by going to Start\run\regedit
but be warned that it contains the programming info about how 95 boots up, so it's possible to take your system out completely if you delete the wrong thing.

once regedit is open, go under the edit menu and choose "find"
then just enter yamser in the space provided, and use the F3 key to continue searching.
In win.ini, especially look for "load=" and "run=" right near the top.
