            Can anyone tell me where to get information about the information in
    a machine check error? I have a machine that is logging a bunch of these,
    and while they say that they are correctable, we are also having a problem
    installing the OS, and I need to narrow it down. I'm not having any luck
    getting through to HP support, so I would appreciate any other help I could.

    thanks
