 Boot Disk for OS/2 2.1 GA isomg FAT File System   Mon  06-28-1993
 This is the minimum I have been able to attain. It will just
 fit on a 1.2 MB floppy

 Use  sysinstx to create the bootable floppy; From c:  sysinstx a:
 sysinstx.com is on the Installation Diskette
 The rest should already be on the C: drive of installed 2.1

Config.sys to be used with above file set

buffers=32
iopl=yes
memman=noswap
SET OS2_SHELL=CMD.EXE
protshell=cmd.exe
diskcache=64,LW
protectonly=yes
libpath=.;\;
set path=\;\
set dpath=\;
set keys=on
BASEDEV=OS2DASD.DMD
basedev=ibm1flpy.add       If PS-2 use ibm2flpy.add
basedev=ibmint13.i13
REM basedev=print01.sys    Remove REM if print01.sys used

Note that print01.sys is not used. This means that printing is not
supported from this floppy. If used be sure basedev=print01.sys is
in config.sys.
REPLACE PRINT01.SYS with PRINT02.SYS if PS-2

The basedev=ibmint13.i13 should support just about any hard drive
I believe and this has the smallest size. It is smaller than the
os2scsi.dmd which also supports SCSI but is not required.

If installing High Performance File System the following should
be in config.sys and the files on the floppy
IFS=HPFS.IFS  /CACHE:64 /CRECL:4   129090 bytes
IFS=CDFS.IFS /Q                     40292 bytes
I am not sure the CDFS.IFS is required if CDROM not used.
In any event when these are added to the floppy it does require
a 1.44 MB floppy.
