2.4.3 Adding Memory
Two slots of 72 pin SIMM (Single In-line Memory Module) sockets are available
for on-board system DRAM (one slot is occupied by the standard 64 M of memory).
To insert a SIMM, place it in at a moderate angle. Note that it fits in the socket in
only one direction. Push it in from an angle to an upright position. The retaining
clips will grab and click into place. When positioned properly, the pins on the top
of the vertical pins should rest in the holes of the SIMM modules.
To remove a SIMM, support it with a finger and use a pen or similar shaped object
to press one retaining clip down. Repeat for the other side. When released, the
clips will push the SIMM up and out of its upright position. Remove the SIMM
from the socket.
3. Peripheral Devices
OPtima PC has an on-board flat panel/CRT controller. An internal cable is used to
connect the computer card to the flat panel screen. If desired, an external CRT can
be connected to the CRT connector on the side of the unit. An external keyboard
can be hot-swapped (plugged in or un-plugged with power on) using the mini-DIN
connector on the side of the unit.
A high speed, local bus IDE controller as well as a floppy controller are also
included. The floppy controller controls the floppy drive (drive A). The IDE con-
troller supports the internal hard drive, which is a 6.x GB drive as of this writing.
The drive is set up in 2.x GB partitions, with sequential drive letters assigned for
each partition. To check partitions, go to Windows/My Computer and select a
drive. The size of the drive partition and how much of it is used will be displayed
in the lower part of the My Computer window. Be sure to verify how much hard
drive space remains before installing software. Filling a hard drive partition to
capacity can cause application anomalies. As a minimum, 50MB should be left
as scratch pad space for an application’s temporary files. If more room for an
application is required, switch to a different drive partition.
Other peripheral support includes two serial ports and a parallel port. The first
serial port is defined as COM1 and is located on the same connector as the CRT
connector on the side panel. The default setting for COM1 is resource address
3F8H (hex). The second serial port is defined as COM2 with a resource address
of 2F8H. COM2 is used for the touchscreen controller and is NOT accessible to
the user. The parallel port is located on the side slot closest to the front and is
defined as resource address 378H and IRQ 7. The parallel port mode is ECP+EPP
(enhanced parallel port). In most instances all of these port settings and re-
source addresses should remain as the default. Consult your peripheral device
(printer, etc.) for appropriate settings for these ports.
4. The Operating System
The operating system for the OPtima PC is Windows NT 4.0. The BIOS is Award
FLASH BIOS.
4.1 BIOS Password Settings
It is not recommended that users change the factory defaulted BIOS settings.
The computer’s CMOS memory has an integral lithium battery that should last for
ten years in normal service. However, one area that may be of importance is the
password settings to allow changes in the BIOS. There are no default BIOS
Supervisor/User password settings as shipped from the factory. The difference
in supervisor and user passwords is that the supervisor can enter and change
the options of the setup menus, while the user can only see the main BIOS screen
and its options, but cannot select any of those options.
