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.

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.
