I currently run Cpm 2.2 for my Trs-80 model 4, but have noticed that it doesn't support a hard drive. I was wondering if anyone out there knows what I have to do to be able to use my hard drive. I have the 3+ version of Cpm as well and it does support my hard drive, although it will only allow me to access 4000k or so of my 15megs. Is there anyone out there that can help me?

This sounds like a trivial answer, but the details are not: Simply 8-{) write a new BIOS / change Your existing BIOS. If nobody else can help You, I have the source code for a BIOS which supports SCSI hard disks. I might dig into it to find the exact mechanism to switch from floppy to hard-disk.
