    10 cooling fans with speed-sensing capability

    11 error codes and messages

    12 error correcting code (ecc) double-data-rate (ddr) synchronous dynamic random access memory (sdram) with serial presence detect (spd)

    13 integrated ethernet controller

    14 monitoring support for temperatures, voltages, and fan speed

    15 power-on self-test (post)

    16 self-monitoring analysis and reporting technology (smart) on hard disk drives for early prediction of failures

    17 read-only memory (rom) checksums

    18 upgradeable basic input/output system (bios) and post code
