Mouse and Keyboard
-
When attaching the mouse and keyboard connectors, be
careful to attach them to the proper connectors. Although they
are physically identical, they are not interchangeable.
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 to 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 3%&X/16 PLUS if you are instailing a
drive that cannot make use of the internal hard disk controller.
Also remember to disable the onboard hard disk controller
hen installing such a drive.
-
If you are having difficulty in formatting the hard disk drive,
try starting over with the Format option in diagnostics.
Setup
-
When installing a hard disk drive, be sure to consult the drive
ty-pe table for the type which fits the drive you are installing.
If there is no match for your drive, use the User Defined
OptiOIL
Adding Memory Modules
-
The total amount of memory must be one of the following
ZMB, 3MB, 4MB, 5MB, 6MB, 8MB. lOMB, llMB, 12MB, 18MB,
ZOMB, or 24MB.
-
256KB, lMB, and 4MB SiMMs can be used. They must be
fast-page mode and have an access speed of t3Ons or faster.
Software Problems
-
When installing a copy-protected software package on the
Eguity 3&SX/l6 PLUS, first try the installation at 16 MHz
If this does not work properly, try switching to 8 MHz for
the installation. If you are sbli unable to load the program
at16MHz,tryloadingitatgMHzandthenswitchto
16 MHz.
-
When running a software program that uses a key disk as its
copy-protection method, try loading it at 16 MHz If this does
not work, enable the Auto Speed option in SETUP.
Power-on Password
-
If you set a power-on password, make sure you do not forget
it. If you do, it wili be necessary to disable it by moving
jumper 12 on the main system board to the A position
