FIRM.COM is a simple to use DOS Floppy image reader/maker. It is compatible with files used by many other disk image reader/writers. It is capable of reading/writing disks of other systems, Unix, Linux, later Mac and some other disks. Image files can be written back to disks of a larger capacity than the original for at least FAT systems! Say a 1.2MB floppy is saved to an image file and the user wishes to restore to a 1.44MB, the image file would be written back correctly for at least DOS systems.

To read or write a floppy image FIRM requires three parameters, the drive to read or write the image to or from, the file to create or write back and and finally the operation to perform either read or write. Care should be taken when reading a new image, as the file will be overwritten if the file already exists! 

FIRM performs some limited bios level error checks, it retries the read/write function 5 times before it aborts with a bad disk, it will display the bios error that caused the abort.

Typing FIRM without any parameters displays the following usage screen...

Compliments & Free to ALL, from Dave Burley....                                 
                                                                                
You must specify the Mirror File to CREATE/WRITE from/to the Drive!             
if you wish to (R)ead  a disk, use the '-r' switch                              
if you wish to (W)rite a disk, use the '-w' switch                              
                                                                                
The arguments can be in any order!!!                                            
It's a 'I don't care' program, you must ensure the disk is formatted correctly  
it will however report any disk errors...                                       
it is capable of creating/writing a file with disks of various sizes/formats..  
(NOTE:- when writing an image the size of destination disk is reported)         
                                                                                
                                                                                
                                                                                
Example 1..:- FIRM FLOPPY.IMG A: -r                                             
(would create the IMAGE FILE <FLOPPY.IMG> from the disk in Drive A:)            
                                                                                
Example 2..:- FIRM FLOPPY.IMG B: -w                                             
(would write  the IMAGE FILE <FLOPPY.IMG> to   the disk in Drive B:)
