SIMM lnstallation
Your computer comes with 8MB of memory on two 4MB
SIMMs. You
1MB, 2MB, 4MB, 8MB, 16MB, and 32MB SIMMs (when
readily available).
The SIMM sockets are organized in two banks (Bank 0 and
Bank 1) consisting of two sockets each. You must install the
same type of SIMM in a bank.
The SIMMs you install must be 32-bit or 36-bit, 72-pin, 70ns,
tin-plated, fast-page mode, parity/no parity DRAM. The
table below lists the 16MB and 32MB SIMMs that are
approved for use in your system. You can install these
SIMMs or their equivalents.

The table below lists possible combinations of SIMMs you
can install; do not use any configuration other than one of
those listed in the table.

Video Memory, Modes, and Monitors
This system comes with 1MB of VRAM soldered on the main
system board. You can increase the video memory to 2MB by
installing eight VRAM ZIP chips (256KB x 4, 60ns, fast-page
mode). You must fill all eight sockets.
The table below lists the video modes supported by the
system.

The table below lists the monitors that are directly supported
by the Mach32 accelerator.
Check the monitor documentation to see if its characteristics
match one of the listed types. If so, select that type in the
Mach32 installation program.
For EPSON monitors, see the second table for information on
the monitor type to select.
If the monitor does not match any of these types, set up a
custom monitor.

System Power Requirements
If the power cord supplied with the system is not compatible
with the electrical outlet, obtain a cord that
meets these
criteria:
P
The cord must be rated for at least 125% of the current
rating of the AC voltage system.
Cl
The cord must be less than 4.5 meters (14.8 feet) long.
Cl
The connector that plugs into the electrical outlet must be
an appropriately designed male grounding-type
connector.
Ll
The connector that plugs into the computer must be an
IEC type CEE-22 female connector.
Do not use or attempt to modify the supplied AC power cord
if it is not the type required for use in your region.
To avoid permanent damage to the computer, be sure the
voltage selector switch is set to the correct input line voltage
before you turn on the power. Verify that the voltage selector
switch is set to the correct setting. The 115 VAC setting is
appropriate for line source voltages between 100 and 120
VAC. If the line source voltage in your location is between
200 and 240 VAC, make sure you set the switch to 230 VAC.
To avoid damage to the
system
board or power supply, do
not exceed a total of 145 Watts power draw.

Keyboard and Monitor
Even if you intend to use this system as a network file server,
you need to connect a monitor and a keyboard to complete
the installation. You may remove them once the installation
is complete.
Mouse and Keyboard
When connecting the mouse and keyboard, be careful to plug
them into the proper ports. Although they are physically
identical, they are not interchangeable, and damage may
occur to the ports or the main system board.
Expansion Boards
If you are installing a video expansion board containing a
secondary controller, it must be an MDA or CGA card with
no BIOS. You must use the computer’s built-m VGA
controller as the primary controller.
You must install an expansion slot cover on any vacant
expansion slots to maintain the electromagnetic emissions
and cooling characteristics of the system.
IBM 16/4 Token Ring Network Adapters
EPSON PowerSpan DT
Do not install Type 1 of the IBM 16/4 Token Ring network
adapter in the computer because the adapter will not
correctly initialize. You can install the Type 3 adapter if you
disable the appropriate shadow memory area and assign the
correct IRQ 9 setting (if you use IRQ 2). For example, if you
set the adapter’s ROM address to DC000h, the RAM address
to D8000h, the RAM size to 16KB, and the IRQ setting to
IRQ 2, you must make the following changes to these
Advanced CMOS Setup options:
Disable Shadow Memory Base option:
