Hardware Installation
depends on the SIMMs used: 256 kB SIMMs allow 1, 2, or 4 MB capacity;
1 MB SIMMs allow 4,8, or 16 MB capacity. Either 256 kB or 1 MB SIMMs
can be used, but the two different types cannot be mixed on the same
board.
If you are upgrading to AVP 2.1.1, you have to add additional memory to
bring the total system memory capacity to 8 MB. To perform this task, you
must first remove the SIMMs that are already installed. You will not reuse
these old SIMMs.
NOTE:
Remove SIMMs one at a time, from right to
the right-hand SIMM first, and the left-hand
CAUTION:left. That is, remove
SIMM last.
Apply only enough pressure on the retaining clips to release
the module. To much pressure can break the retaining
clips or damage the socket slot.
Follow the steps below to remove a SIMM.

Use a properly grounded wrist strap or discharge any static
electricity from your body by touching a nearby grounded metal
object.
Locate the socket that contains the SIMM you wish to remove.
Remove the SIMM in the right slot of the socket.
Gently spread the retaining clips just enough to pull the top edge of
the SIMM away from the clips (See Figure 2-1 2).
Carefully lift the SIMM away from the socket and store it in a
suitable static-free protective wrapper.
Repeat Steps 2 through 4, as necessary, to remove and store
SIMMs from the remaining sockets.
