Until then, I was able to load my app by copying it (offline) from a floppy to a CD and loading it from there. If you've found a way to do this, I look forward to doing what you do when you can remember!

I tried to load them into DOS and was not successful. Having booted MSDOS successfully, I'm now having problems installing the DOS app and guess that there are issues with the CONFIG.SYS and/or AUTOEXEC.BAT files since any attempt to load the app creates a 'Program is too big to fit in memory' reply.Īlso, I'm having problems editing the CONFIG.SYS file since in Edit mode, MSDOS is not getting any keyboard input again - frustrating.Īll the documentation for Tools says it doesn't work in DOS. Note that after the process is completed, the MSDOS system sees the CD drive as Drive R: (strange choice). Also, after changing the boot order to HD-CD-Floppy (your step #9) and rebooting, the system would no longer see the CD as drive A: I had to leave the boot order as CD-HD-Floppy and execute your commands (Step #11) from that boot - which worked fine. I found I had to click on a non-Parallels window and then click back again on the VM window to get any keyboard input to MSDOS. I was successful in installing DOS 6.22 by following your process but had to make a couple of changes.įirst, I had problems with the VM not getting keyboard input passed through to it. Thanks, vespina, for those detailed tips - very helpful. Restart your VM and you are ready to go!! Stop VM and change boot order to HD - CD - Floopyġ2. Execute FDISK and create a primary DOS partition with all the size of the disk, or do whatever partition scheme you want.Ĩ. After the VM starts, you will end with an A: drive, wich is actually the CD with the MSDOS 6.22 ISO imageħ. If Parallels ask you to connect an image file to the CD, do it again in that dialogĦ. Connect the CD to the MSDOS 6.22 ISO imageĥ. Configure the boot sequence to: CD, HD, FloppyĤ. In my case, I created a new VHD with 250 Mb and assigned 4 MB of RAM.ģ. Create a new VM and configure it for MSDOS. This is the trick, because trying to use floppy images was a nigthmare.Ģ.
