Hello! Is it possible to run picogus in Windows 9x? If yes, what kind of drivers we must use for it?

@nahimov, I made it working in the following setup:

  1. OS: Windows 98 SE (eng)
  2. Hardware: setup IRQ on the card that is not used by Windows 98 (in my case it was 3)
  3. Forced picoGUS into the MPU mode with IRQ: something like pgusinit /mode mpu /mpuport 330 in the AUTOEXEC.BAT
  4. Installed the driver using this formula: Control Panel -> Add New Hardware -> No search for installed devices -> Sound, Video Multimedia Devices -> Music Quest MPU-401 compatible.
  5. Before rebooting I went to system devices and changed the port/IRQ forced by the driver installation wizard to ones relevant for me (in my case I/O port address 330, IRQ 3)
  6. After reboot there is a properly installed driver and a working MIDI output port in Control Panel -> Multimedia -> MIDI

There is also a driver from Roland for MPU-401, but for me each time I run a DOS game from Windows, the Windows reports with a blue screen that the device is already busy and Y/N to continue/exit. When I click Y it works, though. But I don't see any port of using it because of the solution above.

In GUS mode all above doesn't work, because drivers use IRQ for hardware identification, and on the IRQ there is a GUS, so drivers see a conflict and don't work/install themselves. At the same time games that use MPU without an IRQ still work fine.
