    I am attepting to upgrade a Slot 1 PII machine 333Mhz 66Mhz FSB to a Socket 370 celeron 500Mhz 66Mhz FSB via slot1 to socket370 adapter. With the celleron installed, the system states that the proccessor is an "i(unknown)500Mhz" The system boots up, but runs at a speed that is literally the equivilent of a slow 386 at 16Mhz. Also with the celeron installed, it incorrectly identifies the amount of RAM as 48MB instead of 64MB wich is installed, (2x32MB DIMMs) (it is reported correctly when the PII 333 is installed.) The motherboard BIOS was set to the correct CPU speed (500Mhz) and runs at a bus speed of 66Mhz. The jumpers on the adapter card were set correctly. (i tried both 66Mhz and auto detect. There was no change between the two settings) My current suspicion is that the CPU is incompatable with the BIOS, but if this is true wouldnt it either not run at all, or run as if it were 1/2 to 1/3 the speed (because it would not be using the casche) instead of running as if it was 1/30th the speed that it is? I have done searches and have found no mentions of any equivelant problems. Also isnt the Celeron PU based on the PII? Wouldnt that let the BIOS detect the CPU as a PII 500Mhz?
    Any advice on this would be greatly appriciated.
