How do you create a blank hard disk and install dos? I have tried msdos 3.3, 5.0, and ibm pc dos 7.0. I have various problems with each under MESS emulation. With 3.3, fdisk locks up and freezes. Msdos 5.0 fdisk runs, but when I try to format I get "unable to write boot sector" or something similar. Has anyone else been able to install dos under MESS? If so, how?
