Acer ACERPOWER ULTIMA User Manual
System Board
This high-perf ormance system board utilizes a 64-bit Intel Pentium
CPU running at 100/66, 120/60, 133/66, 150/60, 166/66, or 200/66
MHz. It has four ISA and four PCI slots (with one PCI- and ISAshared slot) for future expansion. It also has six 72-pin SIMM sockets
that allow memory upgrade to a maximum of 192 MB. To further
enhance system perform ance, the board i ntegrates a 256-KB/512-KB
pipeli ned- bur st c ac he.
Standard features such as two serial ports, one parallel port, a
diskette driv e interface, and two embedded hard disk interf aces are
also incorporated i n the system board. A Univ er sal Serial Bus (USB)
interface is added to the design to enable the system to support
additional peripherals.
The system features the power-management f unction that conforms
to the power-saving standards of the U.S. Env ironmental Protection
Agency (EPA) Energy Star program. It also supports the Plug-andPlay f eatur e. T his f eat ure sav es the user f rom c onf i gurati on t roubl es,
thus making the system mor e user-friendly.
The system board may com e with an optional SCSI /ASM card. Thi s
card enables the system to f unction as a serv er. The system is ful ly
compatible with MS-DOS V6.X, OS/2, UNIX, Novell, Windows NT,
and Windows 95 operating systems.

1.2 ESD Precautions
Electrostatic discharge (ESD) can damage your processor, disk
drives, expansion boards, and other components. Always observe
the following precautions before you install a system component.
1. Do not remov e a component f rom it s protectiv e packagi ng until
you are ready to i nstall it.
2. Wear a wrist grounding strap and attach i t to a met al part of the
system unit bef ore handling com ponents. If a wrist strap is not
avai lable, mai ntain contact with the system unit throughout any
procedure requiring ESD protection.
1.3 Pre-installation Instructions
Always observe the following before you install a system component :
1. Turn off the system power and all the per ipherals connected to
the unit before opening it.
2. Open the system according to the instructions in the housing
install ation manual.
3. Follow the ESD precautions in section 1.2 before handling a
system component.
4. Remov e any expansion boards or peripher als that block access
to the SIMM sockets or CPU socket.
5. See the following sections for specific instructions on the
component you wish to install.
Do not attempt t he procedures described in
the following sections unless you are a
qualified service tec hnic ian.

1.4 Installing a CPU
Observe the ESD precautions when
installing components. See section 1. 2.
The system board features a zero-insertion force (ZIF) socket for
easy CPU install ation.
Follow these steps to install a CPU:
1. Pull up t he socket lever.
2. Insert the CPU, m aking sure that pin 1 (indi cated by a notched
corner) of the CPU connects to hol e 1 of the socket.
3. Pull down the socket lev er to lock the CP U into the socket.
