FDWrite is a program to write a
file to any
sector on a 3.5 floppy. It can
be used to
write a boot sector,FAT table
or just a file.
It uses BIOS routines to write
so there is
no check before the write and
no update of
the FAT after.
This version
only supports 3.5 1.44m
floppy disk. If you recompile
the source so
it can write to the hard drive,
I am NOT
responsable
for any damage. With all that
said, you
have been warned. Don't hollar at
me if you
kill you floppy.
Now, down to the fun stuff. If you write
your bootstrap
code you can use FDWrite to
install
it. Just input the file name, head 0,
cylinder
0, and sector 1. Don't forget to look
at my other
program, Sector ,which will read
any sector
on a floppy to a file.
FDWrite was writen in NASH-IDE 1.1 and
compiled
using NASM 0.95. The asm code is
included
in the zip file.
Here is a screen shot.
FDWrite
has plenty of error checking. Note that
the buffer is limited to 512 bytes.
If your file is
bigger, it can be split into 512
byte chunks.
