enter the BIOS Setup Utility.
b. Select Config and press Enter.
c. Verify the values in the memory section (see page 54).
9. You have finished installing the DIMM. Reconnect all cables.
Notes:
1. If the total memory size is not the same as the value you calcu-
lated, power off the computer and go to page 52 to reinstall the
DIMM.
2. If you changed the memory installed in the computer, you need
to create a new hibernation file. To create the hibernation file,
refer to “Creating the Hibernation Function” on page 55 or see
the

How to Calculate Total Memory Size
Calculate your total memory size in kilobytes (KB) by adding the
DIMM memory size to the base memory size (32384 KB for a com-
puter with 32 MB base memory).
Note: 384 KB is reserved by the system.
For example, if you installed a 32MB DIMM to a computer with 32
MB base memory, you should have about 64 MB.
