has a memory module installed. Run the Setup program to
check the amount of memory installed. You can increase the
memory up to 24MB by removing the original module if
necessary and installing a 4, 8, 16, or 20MB memory module.
Microprocessor Upgrades
The computer's processor can be upgraded by replacing the
original microprocessor with a higher-performance one. The
PGA socket on the main board can accept both a processor on
a daughter board and a processor installed directly in the
socket. A processor on a daughterboard may include 256KB
of external cache; all supported processors include 8KB of
internal cache. The following table lists the speed and voltage
of some of the microprocessors that can be installed.
