/* The Format routine is intended to mimic the actions of the FORMAT command
|

* on MSDOS. We restrict the possible set of operations that Format must use
|
|
* in order to simplify life. The RESTRICTIONS are:
|
|
*
|
|
* -- If the drive selected for formatting is a Quad density drive, then the
|
|
* user will be asked if he wants to format it for 1.2 MB or 360 KB
|
|
* and the format will proceed accordingly;
|
|
* -- For all other types of drives, it will format the disk to the maximum
|
|
* capacity that the drive can handle.
|
|
*
|
|
* The requirements for Format are:
|
|
*
|
|
* 1) there be a disk in a "source" drive that contains a valid boot sector
|
|
* 2) there be a disk in a "destination" drive that is formattable.
|
|
*
|
|
* The algorithm for determining a drive's capacity is as follows:
|
|
*
|
|
* If Source == Destination then
|
|
* error
|
|
* If dosversion >= 3.20
|
|
* {
|
|
* Use generic get_device_parameters and Get BPB.
|
|
* if (the drive is a Quad density drive (1.2 MB), and if user wants
|
|
* to format for 360KB), take BPB for 360KB from the bpbList[].
|
|
* In all other cases, use the BPB of the device.
|
|
* }
|
|
* else
|
|
* {
|
|
* Ask INT 13 for the drive type.
|
|
* If error then {
|
|
* assume 48tpi double side
|
|
* Attempt to format track 0, head 1
|
|
* If error then
|
|
* assume 48tpi single side
|
|
* else
|
|
* if sectors per track = 15 then
|
|
* assume 96tpi
|
|
* Ask user if he wants to format for 1.2MB or 360KB and
|
|
* use the proper BPB from bpbList[]
|
|
* else
|
|
* error
|
|
* }
|
|
*
|
|
* Note that this does NOT take into account non-contiguous drive letters
|
|
* (see 3.2 spec) nor future drives nor user-installed device drivers.
|
|
*
|
|
* Format (dSrc, nDstDrive, nDstDriveInt13) will format drive nDstDrive using an updated
|
|
* boot sector from drive dSrc. We will allocate two blocks of memory, but
|
|
* only one at a time. The first one we allocate is the bit-map of bad
|
|
* clusters that we find during the format. The second is for the boot
|
|
* sector.
|
|
*
|
|
* Returns: 0 Success
|
|
* <> 0 error code
|
|
* 1 => NOMEMORY
|
|
* 3 => Invalid boot sector.
|
|
* 4 => System area of the floppy is bad
|
|
* 7 => Problem in writing in Dest diskette.
|
|
* 8 => Internal error
|
|
* 9 => Format has been aborted by user.

|
* calls to get the Drive parameters and we find the Drive capacity;
|
|
* If DOS version is < 3.2, then there can't be 3.5" floppies at all;
|
|
* The only high capacity floppy possible is the 5.25", 1.2MB floppy;
|
|
* So, we call MyGetDriveType() (int13h, Fn 15h) to find if the
|
|
* change-line is supported by the drive; If it is supported then it
|
|
* must be a 1.2MB floppy; Otherwise, it is a 360KB floppy;
