The
ssss
option
specifies
the
sector
size in bytes.
The
default
value is
128
bytes. The following values
are
allowed: 128, 256,
512, and 1024 bytes.
The
dddd
option
specifies
the
number
of
root
directory
entries.
The
default value is 64;
the
minimum,
2;
and
the
maximum, 1024.
Ramdrive. sys adjusts
the
value
of
dddd
to
the
nearest
sector
boundary. For example,
if
you
give a value
of
25
when
the
sector
size is 512 bytes,
the
25
will
be
rounded
up
to
32,
since
32
is
the
next
multiple
of
16
(there
are
sixteen 32-byte
directory
entries
in
512
bytes).
The
Ie switch lets you use
extended
memory
(above
1
megabyte)
as a
RAM
disk if it has
been
installed.
If
you
use this switch,
you
cannot
use
the
la
switch.
The
la
switch lets you
use
an
extended
memory
board
that
meets
the
Lotus/Intel/Microsoft Expanded Memory Specification for a
RAM
drive,
if
that
board
has
been
installed.
If
you
use this switch,
you
cannot
use
the
Ie switch.
Note
When
you
reset
or
turn
off
the
power
on
your
computer,
any information
stored
in
RAM
disks is lost.
