with only 64K of RAM, so nevermind)
Not sure of this but will 64K be enough RAM to work with a hard drive ?
I believe Dos 2.x was the first that supported hard drives, dunno what
it's minimum RAM requirement is tho.
As an aside I once worked out (by playing about with the total ram BIOS
variable, and soft rebooting) that Dos 1.0 would boot to a prompt in 12K
of RAM, but you could not load anything else. In 16K you could load
things like the editor, but IIRC 16K was the minimum config for the
original 5150.
