9. If you relocated or permanently removed an
EISA expansion card, enter the change into the
EISA Configuration Utility.
See Chapter 5, "Using the EISA Configuration Util-
ity," for instructions.
NOTE: If you removed a PCI expansion card, your
system automatically performs any required recon-
figuration tasks during the boot routine.

dding Memory
The four DIMM sockets (shown in Figure 7-5) on the
system board can accommodate 32 to 512 megabytes
(MB) of dynamic random-access memory (DRAM). The
PowerEdge 2200 systems use 72-bit, buffered, extended-data
output (EDO) DIMMs in these 168-pin sockets. Error cor-
rection code (ECC) checking is performed by the memory
controller in the system board chip set. Figure 7-1 shows the
location of the DIMM sockets on the system board.

Memory Upgrade Kits

Your system is upgradable to 512 MB by installing com-
binations of 32- and 128-MB DIMMs in the DIMM
sockets. The DIMMs should be rated at 60 nanoseconds (ns)
or faster.
Memory upgrade kits can be purchased from Dell as
needed.

DIMM Installation Guidelines

Starting with the socket nearest the system board's edge
and working toward the center of the system board, the
sockets are labeled "DIMM_A" through "DIMM_D"
(Figure 7-5).
When installing DIMMs in sockets, follow these
guidelines:
•
Install a DIMM in socket DIMM_A before socket
DIMM_B, in socket DIMM_B before socket
DIMM_C, and so on.
•
If you install different sizes of DIMMs, start with the
largest (highest-capacity) DIMM in socket
DIMM_A and work toward DIMM_D with the
smaller DIMMs.
DIMM_A
Table 7-1 illustrates these guidelines by listing sample
DIMM_B
memory configurations.
DIMM_C
NOTE: The maximum memory supported in Power-
DIMM_D
Edge 2200 systems is 512 MB.
