    urpmi memtest86+

    This will install /boot/memtest-2.01.bin and add an entry to your boot
    manager. Then reboot, and select memtest from lilo or grub.

    On the bottom there should be a door of some type to acces the dimms, I'd
    open it and verify you have 2gb installed.

    See page 42 of http://static.tigerdirect.com/pdf/HP...ookPC-MnSG.pdf
    for instructions on how to remove, or at least see the memory modules.

    For 2GB, there should be two 1GB dual channel memory modules.
