    I have a zt1230 with a Celeron 1.33 Ghz processor in it. I purchased a Pentium 3-m 1.13 and tried to install it. It installs fine, but when it boots, it hangs on POST. Both processors are 133mhz FSB, obviously same socket. I don't understand why it doesn't work.

    Is there some sort of BIOS update i can do to make this work? The only BIOS I found on HP's site is the version that is currently installed. Has anyone attempted something like this before?

    Thanks,
    Bryan
