Wanting to create an OS/2-bootable 5.25" 1.2MB floppy, and faced with
several apparent choices for accomplishing that goal, I copied the
following three files from os2-ftp.nmsu.edu:

	pub/os2/2.0/ibm/ews/boot20.zip
	pub/os2/2.0/sysutils/se20boot.zip
	pub/os2/2.0/bootdisk.txt

The SE20BOOT.EXE PROGRAM
------------------------
The boot20.zip and se20boot.zip files each unzipped to produce the
se20boot.exe program.  (Both zip files had the same executable image,
dated 8/20/92 2:27p.)  When executed to generate a bootable disk, each
comes back with the following error:

	Failure While Copying (RC=112)

I suspect perhaps there is not enough room on a 5.25" disk for the
install.  Performing CHKDSK on the A: floppy reports errors, and there
appears to only be about 10KB of space remaining on it when boot disk
creation is aborted.  Trying to boot from such an improperly prepared
diskette results in the following error:

	The system cannot load the dynamic link library NAMPIPES
	which is needed to start the system.

Q: How does one get the se20boot.exe program to work for a 5.25" 1.2MB
diskette?  If there are any special switches, then the .zip file should
include a .doc file explaining them.

MANUAL PREPARATION OF BOOTABLE OS/2 DISKETTE
--------------------------------------------
The downloaded bootdisk.txt contains instructions for the manual
geneation of a bootable floppy.  In order to get the file set to fit
on a 1.2MB FD, the author (Morton Kaplon) suggests deleting the
PRINT01.SYS file.  I find that even when I do this, the files still
occupy more space than is available on the 1.2MB diskette.  
Here are the files I tried to copy, and their sizes:

A 5.25" disk only had 1213952 bytes on it.  Two differences between my
files and those in Mr. Kaplan's instructions:

1. his customized CONFIG.SYS file is 439 bytes compared to mine (649).
This is because I didn't get to the step where the modifications were
discussed.  However, the difference here is only around 200 bytes.

2. My "EA DATA. SF" is 16896 bytes while Mr. Kaplan's is only 3584.
Must (can) I make this file smaller (and how?) or can I gain space by
dropping one or more of the above files and still be able to boot
under OS/2?

I have the Service Pack installed on my system, if that makes any
difference. So, what is the proper way to create an OS/2 bootable 5.25"
1.2MB flopy disk?
