✏ NOTE The BIOS cannot determine DIMM size or type when not initialized. If more than 512 MB system memory is installed, the BIOS displays a message at boot indicating memory above 512 MB has not been initialized. The message indicates that additional information is available in Setup. The first time the BIOS detects this condition, a pause follows the message with the option to enter. Setup or to and continue to boot. The message continues to be displayed at boot time as long as the condition exists, however, the BIOS will not pause on subsequent detection. Setup displays the installed memory configuration and shows memory above 512 MB as "not initialized." The board supports the processor and memory module combinations shown in Table 3. Table 3.

If more than four rows of 133 MHz SDRAM are populated, the BIOS will display a message indicating that it will initialize installed memory up to 512 MB at 100 MHz.
