description

This is a convenient tool to generate a hard disk image, pre-formatted according to the MS-DOS specification, and having stated properties.

A disk image named file will be created, large enough to have cyl cylinders, head heads, and sect sectors. Using -M, the value of cyl will instead be interpreted as size in MBytes.

Additional settings include ZIP type disks, FAT32 formatting, and the inclusion of an emulation header.

options

-4

Use the fourth partition table entry. This is the standard for ZIP-disks.

-F

Format the partition using a FAT32 file system.

-M

The argument cyl is given in Megabytes. Recalculate this to get the count in cylinders.

-d

Add a DOSEMU header.

-i id

Specify the MBR identity field as id.

-o

Print to stdout the file system offset.

-z

Use a ZIP-disk geometry. This needs heads=64 and sect=32.
