The FSB stays at 133 ok, doesn't alter at all.
Well either the FSB or the multiplier changed if it's then running as
an XP1800, and since the difference between 100MHz and 133MHz is the
different between operating frequency of an XP1800 and your CPU, that
would make the most sense. If the PLLIC chip has a watchdog timer
function and the system failed to post on the first attempt (a 2nd
attempt may be automatic, not necessarily initiated by you) then it
may revent to the lowest supported FSB speed, even if the BIOS still
shows the original or default CPU speed. If you were to let the
system boot to windows you might see what multiplier and FSB is being
used with a utility like "WCPUID" (can be found via Google search).
Definitely changed unless the machine is off.
I don't know what you mean, more elaboration might help.
I don't mean unplugging the machine from the supply, just unplugging the
drive.
So the system is trying to post with a drive disconnected from both
the power and IDE cables. or only one or the other? You are changing
the jumpers for the drive(s) as needed or using cable select? When
only one drive is used on an 80-conductor cable it should be on the
end of the cable.
By reflahing the BIOS I mean using the MSI update to flash the latest BIOS.
That seems unnecessary, a CMOS reset should resolve it if everything
else is in order.
I have wondered about the battery, but I can't see why unplugging a drive
should do this. However I'll get one and change it anyway.
If it's only the drive being unplugged, it's not the battery that's to
blame. If clearing the CMOS doesn't resolve the problem (each time it
happens) then try clearing it with the power supply unplugged from the
wall, and/or pull the battery too.. it should not ever be necessary to
reflash the board just to get back to the default state.. if all else
fails and you still need flash the board i'd "guess" it's a hardware
fault and that the board needs replaced, but there's really
insufficient evidence to conclude that at this point.
