SIMM lnstallation
The Express.%tion comes with 4MB of memory provided by one
4MB SIMM (single inline memory module) installed on the main
system board. You can install additional SIMMs to increase your
computers memory to 32MB.
There are four SIMM sockets on the main system board. Each
socket can contain either a single-sided or doubl+sided SIMM.
The SIMMs must all be t3Ons (nanosecond), 3Gbit, 72-pin, gold-
leaded, fast-page mode SIMMs.
Be sure to follow these guidelines when you install SIMMs:
same
You can Install one, two, or four SIMMs; you cannot install
l
three SIMMs
Install multiple SIMMs for the best performance; for example,
l
install two 4MB SIMMs instead of one 8MB SIMM
Install the SIMMs in the sockets closest to the front of the
l
main system board first.
Note: To install 32MB of memory, yaa must remave the 4MB SIMM
that came with your system and installfour 8MB SIMMs when they
became available.
Error Codes and Messages
If the computer finds an error, it reports one of the following
types of error messages:
Power-on diagnostic and boot error messages
l
Error tone codes for fatal errors (that lock up the system)
l
Error tone codes for non-fatal errors (that do not lock up the
l
system).
Power-on Diagnostic and Boot Errors
When the poweron diagnostic tests detect an error, the
computer displays a message on the screen (as described below)
and the speaker beeps twice. If the error occurs before the
computer initializes the video display, the speaker sounds a
series of beeps (described in the next section).
Each error is identified by a message number and a countdown
number which the computer uses as it executes the test
associated with the error. For example, the following message is
countdown number 100 and error message number 0018:
100 lOO181:
Invalid confipxatim informtim - pleaso mm SEmp
The table below lists the power-on diagnostic and boot error
messages, and some basic solutions to the problems. Check the
appropriate section(s) in this appendix for other solutions.

Error Tone Codes
If power-on diagnostic tests detect an error but cannot display an
error message, the computer sounds an error tone code. The tone
code is a distinct pattern of beeps that identifies the error, such as
one beep-two beeps--one beep. If the error is serious (fatal) the
computer locks up, but if the error is not serious (non-fatal) you
can continue using your computer.
The tables below list the fatal and non-fatal error codes.
