lnstallation/Support Tips
Power
The Equity II+ has a power supply that is switchable
between 115 V, for USA and Canadian use, and 230 V, for
use in other countries. The voltage switch is located at the
rear of the CPU between the AC inlet and the AC outlet (see
figure below).
WARNING!
The voltage is not changed between the AC
inlet and the AC outlet.
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.
- - -
If the drive does not function normally, make sure
that the drive type has been correctly selected in
SETUP. Also check that any special drivers that
may be necessary have been installed correctly.
Installing Hard Disk Drives
- - -
It is recommended that a 16-bit AT- type hard
disk controller be used in the Equity II+. If you
must for some reason use an 8-bit XT- type
controller, select drive type NONE in SETUP.
- - -
If you are having difficulty in formatting the hard
disk drive, try starting over with 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 option is for
EXTENDED memory ONLY.
- - -
If you are installing an EGA or VGA card, select
SPECIAL OPTIONS as display type in SETUP. This
holds true even when you are using a color or
monochrome monitor with these cards.
When installing a hard disk drive, be sure to consult
the drive type table (on page EQII + -7) for the
drive type which fits the drive you are installing.
Third Party Option Boards
- - -
If you find that some third party option boards do
not function properly in the Equity II+ at the higher
speed, try setting the CPU speed back to 8 MHz.
- - -
If setting the CPU speed to 8MHz allows a 16-bit
board to function, try increasing the wait states by
changing jumper settings on the main system
board. (See page EQII + -002 or EQII + -004 for
12MHz and 10MHz boards, respectively.) The
default setting is one wait state and a larger
number of wait states may enhance the board's
performance at the higher speed.
- - -
When installing an option board which has a
selectable interrupt setting, avoid the use of IRQ2.
For a table of hardware interrupt functions, see
pages EQII + - 002 and EQII + -004 for 12 MHz and
10 MHz models, respectively.
Software Problems
- - -
When installing a copy -protected software package
on the Equity II+, set the the CPU speed to 8
MHz. This has been found to have fewer conflicts
with copy-protection. After the installation, the
CPU can be switched back to the higher speed.
- - -
If a software package does not appear to be
compatible with the Equity II+, try switching the
CPU speed to 8 MHz before giving up. Some
software packages (e.g., IBM Topview 1.0 and
PFS:First Publisher 1.00) have been found to
function only at 8 MHz.
