To remove the system board, follow these steps.
NOTES: Read this entire procedure before you begin.
If possible, print the system setup screens (by pressing the <Print Screen>
key) before you turn off the computer, because you will have to restore the
configuration information after the system board is replaced.

The cables attached to the PRI IDE, SEC IDE, and FLOPPY connectors (see
Figure 4-17) each have two latches securing them to the system board.
Press the latch on each end of the cable connector, and pull to release the
cable from the system board.
The SEC cartridge and heat sink assembly (see Figure 4-21), the guide
bracket assembly, the expansion cards, and the DIMM modules must be
removed from the old system board and transferred to the replacement
system board. Dell recommends removing these components from the
system board while it is still securely mounted in the computer.
