Re: [Freedos-user] Best virtual machine for FreeDOS 1.2

[the b. <bc...@gm...>]

Thank you Bernd and Ruxgulo for your help.

I am using VMware Player because I've used Vmware Server before, I
suppose they are somehow similar.

I also have Bochs to give it a try...

Bernd: I didn't know DOS emulation wasn so difficult... more than 20
options to make a choice!
