Jumper pins

The computer contains four blocks (groups) of jumpers: J3, JS,
119, and J21. To access jumper blocks 119 and J21, you must
remove any option cards that are installed. You must remove the
drive housing to access jumper blocks J3 and JS.

Caution
Do not install or remow any option cards when the driw housing is
removed from the computer. The housing stabilizes the option card riser
board and you could severely damage it if you put stress on it without
the support of the drive housing. Also, do not change the settings in the
reserved jumper block JlO; these jumpers must remain at their factory
settings.

Direct memory access (DMA) improves system performance by
allowing devices to access the system memory directly. This
ability is provided by two 82C37-compatible direct memory
access controllers (DMACs) contained in the 82357. The seven
independent 32-bit DMA channels are listed in the table below
along with their associated DMA controller and their device
assignments.

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, goldleaded, fast-page mode SIMMs.

Error Codes and Messages
If the computer finds an error, it reports one of the following
types of error messages:
l
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
system).

System Configuration utiltty
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:
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.

The table below lists the power-on diagnostic and boot error
messages, and some basic solutions to the problems. Check the
