ILV=
nn
when used
:
it
sets
the interleave
factor
(ratio
of
n:1),
which
determines
the
order in
which
TRSDOS-tl
is
to
access disk
sectors.
Between
disk
accesses,
TRSDOS-II
must
do a
certain
amount
of
processing,
(The
amount
depends
upon your
application.)
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

HDS=
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
tc
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
Disks.
If
omitted,
TRSDOS-II
prompts
you for the
number.
This
number
cannot
be
less
than
128.
The number
for
15-Meg is
306.
PRE=

or
greater).
Default
value
is
128.
DIR
and
ALT
defaults will
be
increased
automatically
to be
greater
than
the
precompensation
to ensure
the
most
reliable
directory
access.
