Hi folks,
In this topic I want to offer you a small but very useful software for retrocomputer lovers, I coded this software myself to read and write the floppy disk boot sector (MBR), the idea of programming this software came from the need to have a way to create a floppy disk that can boot an old computer without resorting to third-party tools like rufus and similar, because I want to have total control over the boot sector for who knows in the future create my own operating system, if someone here aspires to do the same, maybe this software can also be useful.

It is worth mentioning that the software is in beta, so don't be alarmed if you find small bugs, I will improve it soon and add support for hard disks, keep an eye out.

Thank you for visiting my topic, long live the old computers!

Technical information:

CRC32: 10541770
Compatible with: MSDOS and Windows 9X in real mode.
Included files: FBW.EXE

Usage information:

Place the FBW folder in the root of the C:\ disk and enter the directory.

The following commands are available:

FBW READ - Reads the boot sector of the floppy disk on drive 0 and saves it as BOOT.BIN, the generated file will be saved in the folder where the program was started.

FBW WRITE - writes any file named BOOT.BIN to the boot sector of the floppy disk on drive 0, the file must be 512 bytes long and must be in the same folder or directory as FBW.EXE


Used in understanding the floppy disk and its structure: http://www.manmrk.net/tutorials/DOS/PSBOOK/book4/floppyd.htm

I always use John Fine's partcopy.exe

Nice to see more options for the same task though 😀
