FORMAT (S I D=drive I ID='diskname' I Q=query)*
DESCRIPTION
Formats a diskette into 77 tracks of 32 sectors,
initializes the disk allocation map and disk utilization
statistics. An empty (except for one entry for itself)
directory file is established.
Thirteen sectors are allocated for the disk allocation
map (3 sectors) and directory (IO sectors). When a
system disk is formatted, an additional 64 sectors
(2 tracks) are preallocated for the RIO bootstrap
and RIO Debug Get/Save package.
The parameter list specifies the following options:
S
Determines whether or not the disk is to be
formatted as a system disk. Systems disks have
dedicated areas for the bootstrap and GET/SAVE
overlays.
When the'S' option is given and the disk is
being formatted on any drive except 0, the
bootstrap and GET/SAVE overlays are read from
the disk in drive O. If the'S' option is
given and the disk is being formatted on
drive O,a prompt is made for the user to insert
a formatted system disk in drive
a
replacing
the disk being formatted. After this is done,
entering any key will cause the system bootstrap
and the GET/SAVE overlays to be read into
memory and another prompt to be issued. Again
entering any key will result in the bootstrap
and the GET/SAVE overlays being written onto
the disk, thereby making it a 'system' disk.
