Strange beeps: Can L2 cache be faulty on Pentium III?

    [long, sorry]

    I just acquired a used Pentuim III 650MHz, socket 370, which I am
    running on a slot 1 board using a slocket. When I first powered it up
    after installing, the PC speaker kept repeating a rapid series of beeps
    which ascend in pitch. The PC seems to run OK though (I'm using it now)
    though a couple of times it has hung during Win 2k bootup (which is a
    worry). I have had to disconnect the speaker, as it would beep the whole
    time the PC is on. The PC worked fine for 4 years with the old Celeron
    400 on a (different) slocket.

    The strange thing is that WCPUID tells me there is no L2 cache - see
    WCPUID output at end of this post. There should be 256kB!

    A bit of googling tells me that for an AMI BIOS, 11 short beeps mean a
    cache error. My beeps are too fast to count but there could be 11.
    Surely the beeps would all be the same pitch though, not rising pitch.
    And they would be slow enough to count, and have gaps between them.
    Also, it doesn't prevent the PC booting up.

    Is it possible for the on-chip L2 cache to be faulty? Maybe the CPU is
    loose in the slot 1 connector? I have wiggled and shoved it in as well
    as I can though (but I can't get the retaining clips back to hold the
    slocket in, so I'm running without them).

    I cleared CMOS and reentered the old values in BIOS setup. It still beeps.

    I might try disconnecting all connectors (HDs etc) and reconnecting firmly.

    Please help - any ideas?

    thanks
    Roger

    Go into the Bios settings and turn the level 2 cache off and see if the
    problems persist.
