BOOTTHRU 1.0
This program allows you to boot from your hard drive even if your
floppy drive is ready. It is written entirely in Assembly language
and has been tested on three different computers ranging from an XT
clone to a 386DX clone. In all cases, it functions as expected. I
tried a similar program on the board and found that I could not use
my floppy disk under DOS 5.0 after it had been updated by the
program, as a result, I wrote my own.
This program is NOT free software. I would appreciate a
contribution of $5.00 sent to the following address.

I would also appreciate hearing from anyone trying this program who
has any difficulties or suggestions for improvements.
I check my mail on CRS about twice a week and will respond to any
problems encountered as quickly as possible. My sign on name is
Michael Wegemer and I am usually in the IBM conference (2),
however, I check for mail in the main conference as well.
As far as use goes, the program contains instructions when it is
started. For convience, I have included a copy of them here.
This program is designed to allow you to boot
your computer while a disk is present in the
diskette drive. It accomplishes this by
modifying the boot sector of the diskette.
Usage is:
BOOTTHRU x
where "x" is either A or B
if x is omitted, A is assumed
You are given an option to process another
diskette when the current one is finished
The diskette must be initialized and a non-system
diskette before processing. If a system
diskette is used, it will no longer function
as a system diskette. (You will have to
install the correct boot sector with the DOS
SYS command.) Please note that this program
will ignore any SUBST that may be in effect.
Do you wish to proceed?
I have put in as much diagnostic checking as I can at this point.
I can determine if a diskette is formatted, but I have not found a
convlusive way to tell if it is a system diskette or not. Error
messages are as complete as I can make them with as much
information as possible. At this point, I have no plans to release
the source code. This program must be run for any disk that will be
in the diskette drive when you boot. It is not necessary (actually
will have no effect) to copy the program to each disk. It must,
however, be run to modify the boot sector of any disk that will be
in the floppy drive when you boot.
