- install DOS 6.22
- load drivers for a CDROM drive and a mouse
- load drivers for the network card
- reduce CPU load
- installing a browser
My host system is a typical WinXP machine with 1280*1024 display.
I used VirtualBox 1.3.8, 1.4.0 and 4.1.8 (the latter under Ubuntu 10.04). VirtualBox 4.1.8 specifics:
- add a floppy disk controller
- disable hardware virtualization
- PIIX3 IDE
Last two choices are on the safe side; perhaps you can do with the defaults.
Hint: once you feel familiar with CDROM images you can collect all your drivers and applications there and significanctly speed up your installation process.
Installing DOS 6.22
Create a new VM using the OS Type DOS defaults: 32M memory and a 500M hardisk. Use defaults all the way until the machine is created; next, connect either your host floppy drive A: or an image - with the first DOS 6.22 setup floppy.
Start the VM and follow the instructions for loading DOS.
When done: reboot after removing the 3rd floppy and there you are....
