newdisk prepares a new hard disk to be bootable from by X680x0. It should NOT be used for floppy disks.
It creates a disk mark for IOCS to determine the disk geometry, writes the primary boot program (mboot), and creates empty partition table. The option are as follows:
-n
Dryrun mode. Nothing is written to the disk.
-f
Force. Usually, when newdisk detects existing disk mark, it aborts with some error messages. -f option prevents this behaviour.
-c
Check only. newdisk looks at the disk whether it is already marked.
-p
Do not create the partition table.
-m mboot
Specifies the mboot program to be written.
