ILV=
nn
when used,
it
sets the interleave factor (ratio of
n:1), which determines the order
in
which TRSOOS-II
is
to access disk sectors. Between disk accesses,
TRSDOS-II must
do
a certain amount of processing, (The
amount
depends
upon your
applicat'lon)
The
proper
ILV
factor
can
reduce the processing by minimizing
disk
rotation between accesses.
If
you omit the option, nn
defaults to 10.
Hard Disk only
HOS=
nn
tells TRSDOS-II the
number
of heads on the
drive. This
is
required for Hard Disks. If omitted,
TRSDOS-II
prompts
you for the number. This number can
be
1 to
6,
For 15-Meg the
number
is
6,
CYL=
nnnn tells TRSDOS-II the
number
of cylinders on
the drive This is required for Hard
D"lsks.
If om'ltted,
TRSDOS-II
prompts
you for the number. This
number
cannot
be
less than 128 The
number
for
15-Meg
is 306,
PRE =
nnn
tells TRSDOS-II the precompensation start
cylinder
(128 or greater) Default value
is
128. DIR and
ALT defaults
w'lli
be 'Increased automatically to
be
greater
than the precompensation to ensure the most reliable
directory access.
verification level is one of the following:
FULL reads the value of each sector
and
compares
that
value with what was written during formatting
NONE
No
verification is done. verification level is optional:
if omitted, FULL
is
used.
Nith TRSDOS-II, this FORMAT consists of 32 sectors
per
track
,nstead of the TRSDOS 26, Because of this,
floppy
diskettes
formatted
by
TRSDOS-II cannot
be
used
under
TRSDOS
and
vice
versa,
For more details on FORMAT, see your TRS-80
Computer
owner's
manual.
Examples
FORMAT 5
(ENTER)
formats the diskette on Drive
5,
using the default values for
options. You will be
prompted
for HDS
and
CYL numbers.
FORMAT 2
(ENTER)
formats the diskette in floppy Drive
2,
using the default values for
floppy
diskettes
FORMAT
(ENTER)
prompts
you for the drive to use before it
begins
formatting Since
no options are specified, the
disk
will have the option's defaults,
If
hard
disk
you will
be
prompted
for HDS
and
CYL numbers,
FORMAT:5
{DIR~75}
(ENTER)
formats the
disk
'In
Drive
5,
placing the primary directory on
cylinder
75. You will be
promoted
for HDS and CYL numbers.
