How do I set up pcsim, the DOS emulator?

[Editor's Note: this product does not exist in AIX 4.x.]

You must have a bootable DOS diskette to install pcsim. Either DOS 3.3,
4.x, or 5.0 will work. IBM do not officially support DOS 5.0 for pcsim
but I have no problems with it. Just don't try to be fancy with the UMB
and memory manager stuff.

With a bootable DOS disk in the drive, do:
$touch /u/dosdrive (this is the AIX file for DOS emulation)
$pcsim -Adiskette 3 -Cdrive /u/dosdrive
You would now get an A prompt. Type:
A> fdisk
Create the virtual C drive of whatever size you choose. Make it large
enough for your needs since you cannot enlarge it later.
A> format c: /s (to format the virtual C drive)
Now exit from pcsim with ESCpcsim (Esc key followed by pcsim).

Now create a simprof file. Following is a starter:

Adiskette : 3
Cdrive :/u/dosdrive
lpt1 : name of printer queue
refresh : 50
dmode : V
mouse : com1

You can now start pcsim anytime by typing pcsim. Make sure no floppies
are in the drive. For further information, refer to publication
