CPU
SPEED switch
There are no DIP switches on the Equity Ile. However,
there is a CPU SPEED switch on the front of the unit in
the lower left hand comer.
The CPU SPEED switch selects between 8MHz and
12MHz. When the computer is running at 8MHz, the
power light is orange, and at 12MHz, the light is green.

EQUITY Ile
Installation / Support Tips
Power
The Equity
He
has
a power supply that is switchable between
115 V, for USA and Canadian use, and
23fIV,
for
use
in other
countries. The
voftage
switch is located at the rear of the CPU
between the AC inlet and the AC outlet. (see figure below)
WARNINGI
The voltage is not changed between the
AC inlet and the AC
outlet.
lf
the CPU is switched for
230 V in order to
function
in Europe, only peripherals
certified for use at 230 V should be plugged into the
outlet.
Installing Floppy Disk Drives
-
When installing a floppy disk drive as drive B,
remember to set the drive select jumper to the
second position and attach the pass-through
connector on the floppy drive controller cable to the
drive, not the end connector.
Equity Series Computers
If
the
drive
doea
not function normally, make sure
that the drive type
haa
been correctly seNcted In
SETUP.
Aleo
check that any
apeolal
drivers that
may
be
v
have been
tnsta5ed
correotly.
Installing Hard Disk Drives
ft
is
reoommended
that a W-bit AT-type hard
disk
controller be used in the Equity IN, if you are
installing a drive that cannot make use of the
internal HI board.
AJso
remember to disable the Hi
board when Installing such a
drfve.
lf
you are having difficulty In formatting the hard
d&k drive, try starting over
wfth
the Unconditional
Format option in diagnostics.
Setup
-
When installing an optional expanded memory
board, do not list the memory under the memory
expansion option in SETUP. That
optfon
is for
EXTENDED memory ONLY.
When installing a hard disk
drfve,
be sure to
cons&
the
drive
type
tables (on page
EOlfe-4)
for the drive
type which
ffts
the drive you are installing.
Adding Memory Modules
The
total amount of memory must be one of the
following: 1 MB,
2MB,
3MB
or
5MB.
-
Memory banks must be filled with one size SIMM.
You cannot mix SIMM types in one bank.
Software Problems
When installing a copy-protected software package
on the Equity lie, first try the installation at 12 MHz.
lf
this does not work properly, try switching to
8 MHz for the installation.
lf
you are still unable to
load the program at 12 MHz, try loading at 8MHz
and then switching to 12 MHz.
When using a software pa&age that uses a
keydlsk
as it copy-protection method, try loading it at 12
MHz. lf this does not work, enable the Auto Speed
option in SETUP.
EQlle-5
![](asset-6.png)
EQUITY lIe
Power-on Password
Make sure that you do not forget the Power-on
Password should you set one up.
if
you do, it will
be
nW%ssary
to disable it by moving jumper 1 on
the main circuit board to the B position.
EQlle-6
lf
you enable network server mode after
instelling
a
password, the computer prompts you for that
password before allowing you to
aax
the system
-
as long as you boot the system from the
Fleferenos
diskette.
However,
if you install MSDOS on the hard disk
and buot from that
d&e,
the prompt no longer
appears. The computer shows the normal MS-DOS
prompt (e.g.,
C>),
but it still requires the password
before allowing you to access the system in
network server mode.
