Installing a Microprocessor
Installing a Microprocessor
You can install a second microprocessor in your PC Server 520.
This microprocessor works with the Pentium microprocessor of the
same speed that is in your PC Server 520.
After installing the second microprocessor, your PC Server 520 can
operate as an SMP server. With symmetric multiprocessing, certain
operating systems and application programs can distribute the
processing load between the two microprocessors. This enhances
performance for applications such as database transactions, graphics
or CAD (computer-aided design) programs, and modeling or
simulation programs.
Before you begin, be sure you have:
Ÿ Read “Electrical Safety” on page 179 and “Handling
Static-Sensitive Devices” on page 180.
Ÿ Removed the server side cover (see “Preparing to Install
Options” on page 181).
Ÿ
Obtained one of the following operating systems (optional)
at the specified release level:
– IBM OS/2 for Symmetrical Multiprocessing Version 2.11
(OS/2 2.11 for SMP) or later
– Microsoft Windows NT 3.5 or later
– Novell NetWare 4.1 for SMP
Ÿ Located the documentation supplied with your computer
and operating system
Notes:
Ÿ
Install the microprocessor before you install OS/2 2.11 for
SMP. If you have already installed OS/2 2.11 for SMP,
you must add the statement
PSD=OS2APIC.PSD
to the
CONFIG.SYS file or reinstall OS/2 2.11 for SMP.
Ÿ
The illustrations in this procedure might be slightly
different from your hardware.
