2. Restart the system and then enter your BIOS (or CMOS) Setup. In most systems, this
is done by pressing the Del or F2 key during the POST but before the boot process
begins (see your system or motherboard documentation for details). Once in BIOS
Setup, verify that the memory count is equal to the amount that has been installed. If
the count does not match what has been installed, go to the defect isolation proced-
ures.
3. Find the BIOS Setup options for cache and then set all cache options to disabled
if your system supports this option. Figure 6.18 shows a typical Advanced BIOS
Features menu with the cache options highlighted. Save the settings and reboot to a
bootable floppy or optical disc containing the memory diagnostics program.
Figure 6.18 The CPU Internal (L1) and External (L2) caches must be disabled in the system BIOS Setup
before you test system memory with most memory testing programs; otherwise, your test results will be in-
accurate.
