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|
|-v||Verify that file matches disk contents|
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
- 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.
