a group of dos emulator developers.

+
+To install DOS on a pseudo hard disk under doscmd:
+
+    1)	Create a .doscmdrc with at least the following:
+
+	    assign A: /dev/rfd0_1440_3.5 1440
+	    assign A: /dev/rfd0_720_3.5 720
+	    assign hard boot_drive 80 2 2
+
+	You may need to adjust the raw files for the A: drive to match
+	your system.  This example will cause the HD drive to be tried
+	first and the DD drive second.
+
+	Note that you should only use raw devices or files at this point,
+	do not use a cooked device!  (Well, it would probably be okay
+	for a hard disk, but certainly not the floppy)
+
+	boot_drive should be the file name of where you want your bootable
+	image to be.  The three numbers which follow "80 2 2" say that the
+	drive will have 80 cylinders, 2 heads and 2 sectors per track.
+	This is the smallest drive possible which still can have MS DOS
+	5.0 installed on it along with a config.sys and autoexec.bat file.
+
+	You might want to create a larger boot drive.
+
+	The file boot_drive must exist, so use the command touch to create
+	it.
+
+    2)	Insert a floppy disk into the A: drive which is bootable to MS-DOS
+	and has the commands fdisk, format and sys on it.  You should also
+	copy the file instbsdi.exe onto the floppy by either mounting it
+	with the msdos file system type or by using mtools.
+
+		(i.e. mwrite instbsdi.exe a:)
+
+    3)	run doscmd.
+
+    4)	At the > prompt type "fdisk"
+
+    5)	Select "Create DOS partition or Logical Drive"
+
+    6)	Select "Create Primary DOS Partition"
+
+    7)	Tell it how big to make it (I say use the whole drive.
+	It is pretty tiny after all.)
+
+    8)	Get out of FDISK by hitting <ESC> a few times.
+
+    9)	doscmd will now abort (will try and fix this in a future version)
+
+    10)	start up doscmd again, leaving the floppy in the drive.
+
+    11)	At the > prompt, type "format c:" and follow the instructions.
+
+    12) At the > prompt type "sys c:"
+
+    13) Get out of doscmd.
+
+    14) Either remove the floppy from the drive or add the line
+
+	    boot C:
+
+    	to your .doscmdrc
+
+    15)	You should now be running DOS off of your new disk.  You will
+	probably want both config.sys and an autoexec.bat file.  To
+	start with, you can say:
+
+	> copy con: config.sys
+	LASTDRIVE=Z
+	^Z
+	> copy con: autoexec.bat
+	@echo off
+	instbsdi.exe
+	^Z
+
+	
+    16) Quit doscmd.
+
+    17)	You know have a bootable pseudo disk which will automatically call
+	the magic "instbsdi" program, which installs BSDI disks.  To use
+    	them add lines to your .doscmdrc such as:
+
+	    assign D: /usr/dos
+    	    assign P: -ro /usr/prb
+
+    	Not ethat you will not always be able to access every file due to
+	naming problems.
