I installed FreeDOS on a Dell 1.7 Pentium with 756 meg ram. I got a C: prompt and I type type instead of cat to view a file. I notice the autoexec.bat file runs fnet.bat if it exists so I assume that is for starting FreeDOS networking.
Also I got several ram use options when I booted. No idea what they meant but I get the ram tradeoff situation with a 640K OS.
