I'm attempting something that might seem crazy but I got stuck at the end. I am installing Windows 95, on a flash drive, using a PC with modern hardware (Not a virtual machine!). I got around the memory issue (16GB > 1GB) with MaxPhysPage and the Windows protection error issue (4.0GHz > 2.1GHz) with CPU95FIX. I can boot into Windows 95, the basic things work (keyboard and screen at really low resolution), but the mouse... It is recognized as a mouse but even a single tiny movement can make it teleport everywhere, randomly click at random places and drag from random places to random places.

At first, the installer also had this issue but the installer has a flag for it. SETUP /iL makes the installer load the Logitech mouse drivers instead of the normal mouse drivers and that seemed to fix the mouse for the setup. However, I couldn't figure out how to load these drivers on the actual installation so the mouse works normally there. If there is a file inside the installation CD, what's the path to it? If the installation already has the driver, how can I activate it? If there is a 3rd party driver I need to install, where can I get it from?

The mouse is a wireless Logitech M705 connected via Logitech's USB dongle. The same dongle is also connected to the keyboard. I am yet to figure out how it works at all but it works and I'm not going to question it.

  • Probably autoexec.bat; I don't know what the driver's called, but if you find out and it works please post an answer.

  • back in the days we used mostly the gmouse.com (genius) for all the mouses that was making a fuss. Do you have USB legacy support enabled in BIOS ? The USB dongle is connected to USB 2.0 I hope ... the 3.0 ports are not reliable for old HW or SW...

  • @Spektre Yes, I do have it enabled. Also I had it connected to USB 3.0 during the setup and the mouse worked flawlessly with the setup drivers.

  • some crazy gaming mouses have a switch for sensitivity modes may be your setting is just too high (usually some click pattern can change it) but I do not use such mouses so I can not help there if the case ... they are teleporting like you sad even on new OS from mine point of view too. In case of need for mouse durring install you can temporarily use keyboard mouse left ATL + left shift + num lock ...

Windows 95 Setup and Windows 95 will probably be using different types of drivers. Setup runs direct from DOS, so will use real-mode drivers, whereas Windows 95 will prefer virtual device drivers (for the CPU's "virtual mode" ), to avoid having to switch to and from real mode every time it talks to the mouse. It can use real-mode drivers if necessary, but Windows 95 includes VMOUSE.VXD which works with most mice (except yours).

On a modern system, the speed penalty from a real-mode driver won't be an issue. If you can load a real-mode mouse driver in DOS (through CONFIG.SYS and AUTOEXEC.BAT) before Windows boots, Windows should use the real-mode driver instead. If you can't fish the real-mode driver out of the Windows 95 CD, you could try one of the drivers listed here.

    Incidentally, Setup from Windows 95 is running under Windows 3.1.
