FLPYIMG: Read/Write Floppy Image
flpyimg will read, write, and verify entire floppy
disk images, or just the boot sector. It's useful for backing
up boot floppies, or for preparing boot floppies with a
custom operating system.
Reading a floppy image from drive: and writing it to file:
flpyimg switches... drive: file
Reading a floppy image from file and writing it to drive:
flpyimg switches... file drive:
- -b Boot sector only, not the entire disk.
- -h Help
- -v Verify that file matches disk contents.
Examples
Read the entire contents of disk a: and write it to
the file foo.img.
flpyimg a: foo.img
Read the first 512 bytes of boot.img and write
it to the boot sector of disk b:.
flpyimg -b boot.img b:
Read the entire contents of disk b: and verify that
it matches
the file foo.img.
flpyimg -v b: foo.img
Notes
- flpyimg is a DOS program, meaning it will not
handle long file names.
- The only disk drives flpyimg will write to are
drives A: and B:, to avoid accidental destruction of
drive C:.
- The floppy disk must already have been properly formatted
before flpyimg can write to it.
- Windows XP will not read 160Kb single sided DOS disks at all,
at least not disks formatted by DOS 1.0.
DOS 1.0 does not set the BIOS parameter block (BPB) correctly
in the boot sector.
Windows 95 will read them.
