![]() It is for this reason that you need to install Windows 95 on a disk image and tell DOSBox to boot from it: so that the bundled version of MS-DOS is available to Windows, which provides the necessary interface. As such Windows 9x is much more intimately tied to the version of MS-DOS it came with, unlike Windows 3.x, which can run pretty well even on DR DOS, despite Microsoft’s best intentions. Windows 9x, on the other hand, requires a much larger and deeper API/ABI surface of DOS to function, some of which is very poorly documented and understood. Other than that, games typically need access to sound, video and network hardware, with which DOS itself has little involvement. More juggling of disk images and such, but if you can get the installer to complete then you should be able to just boot the mounted disk image and enjoy Win95, although with scaling and mouse capture weirdness if you're not in full screen.īest advice is go with the guides and start from scratch, but the general idea is that it is possible, though not as easy as you would hope.ĭOSBox as a project generally targets games, and as such its built-in DOS implements only the subset of DOS used by games, which is mostly memory management (including XMS and EMS memory), high-level file system access (files and directories, not disk sectors, aside from the occasional PC booter) and process spawning.Copying Win95 installation files over to your disk image so you can run that installer after you've installed MS-DOS on it.This usually involves juggling of virtually inserted 3.5" floppy disk images with DOSBox to format and install on the raw disk image you created. Install real MS-DOS 6.22 on the image.you can't just mount a subdirectory on your host machine. This has to be mounted as a disk image, i.e. General steps involved to get Win95 running are: Windows 3.1 and later are all picky about what DOS they run on top of and will crash/halt/exit if you're using FreeDOS or DOSBox's DOS emulation. This won't work because most importantly the DOS emulation that DOSBox provides will NOT run Win95 - you'll need to actually install a real MS-DOS version to install and later run Windows. I imagine you simply have a disk image with Win95 on it and you're trying to run it. There are other web pages you can search on the web which will walk you through installation of Windows 95 on DOSBox (e.g. There is another project called DOSBox-X which attempts to address some of the quirks that prevent Windows 95 from running on it and as such they have guides on how to do it. I went through the motions several times before I got it to work, but the main issue is that DOSBox doesn't really work out-of-the-box with Win95. They could have caused a major disturbance and potentially started a fire.Windows 95 sorta-kinda works on DOSBox. Imagine if someone had war dialed into the machine. ![]() I made sure to turn off the modem and did not bring it over to the new DOSBox setup. At some point it had been remotely operated through some kind of Norton remote control software. The old PC was still connected to a modem with a dedicated phone line. To this day, unless something drastic has changed, a billion $ company is running DOSBox in production (and I literally mean production).Īlso, a side note. The first few attempts caused some sirens and alarms to go off in the building, which was "exiting", but after fiddling with the emulation speed I managed to get it to work. My solution was to copy everything from the old HDD to a new computer, install DOSBox and configure the serial port. Previous upgrade attempts involved virtualization, but that did not work since the program ran too quickly on modern hardware. It was therefore decided that this PC should be replaced/upgrade if possible.Īfter investigating I learned it communicated with a PLC through the RS-232 interface and ran some special sauce software from a company that stopped existing in 1995. ![]() This machine had been chucking along since 1992 and now someone high up had been made aware that it could be a potential risk if this machine stopped working. They had an old IBM PC running IBM DOS which controlled a vital system at the beginning of their production line. Back in 2012 I worked at a large manufacturing company.
