How to Open a Desktop Case
The figures show the plastic bezel, screw locations, and cover
motion for a desktop case.
Chapter 1 - The Big Picture
Caution:
Whenever you open the case or work inside the computer there is danger of
electrostatic discharge. Electrostatic discharge can permanently damage
your equipment. Always ground yourself by touching the system cabinet
before touching any internal component. We strongly recommend using an
antistatic wrist strap attached to cabinet ground.
To open a desktop case:
1. Turn off the monitor and system unit power. Unplug the AC
power cables and disconnect any other cables attached to
the back of the system unit.
2. Remove the plastic bezel from the back of the case by
pulling it away from the case.
3. Unscrew the five mounting screws at the back of the case
that hold the case cover to the system unit chassis.
4. Slide the case cover back and up. Be careful not to snag any
cables or connectors inside the case.
5. Set the case cover aside while you work on your system.
6. When through, reattach the case cover, screws, bezel, and
cables in the reverse order.

How to Open a Vertical Case
The figures show the plastic bezel, screw locations, and cover
motion for a vertical case.
Chapter 1 - The Big Picture
Caution:
Whenever you open the case or work inside the computer there is danger of
electrostatic discharge. Electrostatic discharge can permanently damage
your equipment. Always ground yourself by touching the system cabinet
before touching any internal component. We strongly recommend using an
antistatic wrist strap attached to cabinet ground.
Opening a vertical case is almost identical to opening a desktop
case.
To open a vertical case:
1. Turn off the monitor and system unit power. Unplug the AC
power cables and disconnect any other cables attached to
the back of the system unit.
2. Remove the plastic bezel from the rear of the case by pulling
it away from the case.
3. Unscrew the six mounting screws at the back of the case
that hold the case cover to the system unit chassis.
4. Slide the case cover back and up. Be careful not to snag any
cables or connectors inside the case.
5. Set the case cover aside while you work on your system.
6. When through, reattach the case cover, screws, bezel, and
cables in the reverse order.

2. The Mainboard
The mainboard is the large circuit board located at the bottom
of the system unit case. It is the heart of your computer system.
This board contains the central processing unit (CPU),
secondary cache subsystem, expansion slots, ports and
connectors for other computer components, and the system main
memory or RAM.
Your mainboard includes:
♦Intel Pentium (TM) Processor running at 60Mhz, 66Mhz, or 90 Mhz
♦Small Computer System Interface (SCSI) host adapter socket
♦Optional 256K or 512K secondary system cache
♦Integrated Windows compatible Business Audio that supports
ADPCM compression
♦Integrated floppy drive controller
♦Two local bus IDE hard drive interface ports supporting up to 4 IDE
devices
♦Enhanced Parallel Port
♦Two full-function, RS232, 16550-compatible serial ports
♦High-speed system memory; expandable from 2MB to 192MB
♦Flash BIOS; relocatable to 32-bit high-speed RAM for faster
performance
♦Five 16-bit ISA expansion slots
♦Three 32-bit PCI, local bus, high-speed expansion slots
♦Clock/calendar with on-board battery backup
Mainboard Features
Chapter 2 - The Mainboard
23
Chapter 2- The Mainboard
PCI Local Bus 32-Bit High Speed Expansion Slots
The three PCI local bus, high speed expansion slots move
information at up to 133 MB/s. This provides an extremely high
performance, 32-bit interface to support high speed, local bus
video adapter cards and other peripherals such as LAN adapters
and hard disk drives.
Secondary Cache Subsystem
The secondary cache subsystem enhances the performance of the
CPU. The integrated cache controller and a cache memory
SIMMs provide the secondary cache subsystem for the system.
Either one 256K Cache SIMM or one 512K cache SIMM
provides the cache memory.
Keyboard Selectable Speed
You can increase system performance by activating Turbo mode
with the keyboard.
<Ctrl><Alt><+> activates turbo mode (default).
<Ctrl><Alt><-> disables turbo mode.
Note: Some Pantera systems have a Turbo LED and Turbo button on the
front of the case. The Turbo button and Turbo LED are not used on
Pantera systems. Only the keyboard command enables or disables
turbo mode.
24
Chapter 2 - The Mainboard
On-Board Peripherals
Your mainboard has all of the standard peripheral interfaces and
many extras built in. This eliminates the need for many
peripheral expansion cards and greatly enhances system
reliability.
The integrated peripheral interfaces include:
♦Optional SCSI port (supports both SCSI-1 and -2 type devices)
♦Two serial ports
♦Parallel port
♦Floppy drive controller
♦Two IDE hard drive controller ports each capable of controlling two
hard drives
♦Business audio with speaker output jack, alternate internal
speaker output, and microphone input jack
Serial Port
Your mainboard has two RS232C asynchronous serial ports,
which are generally referred to as COM1 (9-pin) and COM2
(25-pin) ports. The serial ports are used to attach mice, serial
printers, modems, or other serial peripheral devices. Both serial
ports are 16550 UART compatible for higher data transfer rates.
You can install up to two additional serial ports (COM3 and
COM4) simultaneously in your system. However, MS-DOS does
not manage more than two COM ports simultaneously very well.
Therefore, while you can install and use four COM ports, do not
attempt to use more than two at the same time or you may run
into problems. Specifically, you should not try to use COM1 and
COM3 at the same time, or COM2 and COM4 at the same time.
