Dos tool to create floppy image
Posted 16 June 2010 - 04:40 AM
Is there a Dos based tool that can create floppy image file for drive A:?
Hope it can give me the exact floppy image file that is used for booting emulated floppy images off CD.

You can use extract from http://www.winimage.com to populate a diskette once made.
There are plenty of utilities that will convert a real diskette to floppy, and if one of these is used with a ram floppy disk, then one can make diskettes in memory, and use something like the freedos or drdos 'diskcopy', or savedskf (IBM EWS: look for loaddskf).
Because loaddskf and savedskf are DOS/OS2 bound apps, Windows NT loads them as an OS/2 app: unfortunately, OS/2 support was removed in Windows 5.1 and later, along with the essential utility 'forcedos'.
I use some proggie hight 'dskimage', there are MSFT and IBM versions of these around.
The best bet i suppose would be diskcopy from DR-DOS or freedos. These support both reading and writing disks.
If ye have a mob of disks to make into directories, there is always 'os2hdd'. This will extract diskettes into directories with the disk label, eg DISK1 to DISK1 &c. It simplifies translating diskette images into ready-to-install OS/2 directories, but it's a straight DOS app.

- Boot CD
- Run GRUB.EXE from another drive
- Determine the floppy's size with geometry (fd0)
- quit GRUB4DOS
- Create a file of the appropriate size on the other drive
- Run GRUB4DOS again
- dd the (fd0) to the image file on the other drive

[*]Create a file of the appropriate size on the other drive
[*]Run GRUB4DOS again
Is this create-a-file step really necessary? What if the "appropriate size" is smaller than 1.44M? Can we avoid the whole "run GRUB4DOS again" step and do it in one-shot?
