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.

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.
