    I have a Compaq Proliant 5000 with 320Mb RAM.

    If I boot up either linux 2.4.22 or 2.6.4, it only identifies 12Mb of memory.

    With 2.4.22, the kernel parameters "mem=exactmap mem=640k@0M mem=319M@1M"
    worked to make the kernel identify all of the memory.

    I have tried the same with linux 2.6.4, but with the above flags the
    kernel will not boot. With "mem=320M", the system boots, but it still
    thinks it has only 12Mb RAM.

    Something I'm missing or did this change between releases?

    Thanks in advance,
