[plex86] Pragma Linux boot floppy works in plex86

[Kevin Lawton]

If you want to just try out Linux in plex86 without
needing a big hard disk image file, you can boot
the Pragma Linux boot disk.  I uploaded it to:

  ftp://ftp.plex86.org/guestOS/1.44_pragma386

...and added conf/pragma for kicks to CVS.

  plex86 -f ../conf/pragma

Needs more than 8Mb to boot so I used 16 in the conf file.
Root passwd is 'root' for the boot floppy.
