Athlon 1.3GHz cpu
Celeron 300A processor.

These are a few and courtesy of Tech Enclave here is a link about a place in China that produced a CPU called Godson II which is the equvalent of a Pentium III as well.

Hope this helps.

you could only upgrade the processor and RAM in this condition i.e.

you can only change your an upgraded p-III processor like 1.0 GHz, 1.1 GHz or 1.3GHz and
upgrade the RAM by changing to 256 in each slot.

that is all what u can do with ur pc

Ese procesador usa el FSB en 133 Mhz y el motherboard tiene el FSB en 66 mhz, tenés que entrar en la bios y cambiarlo por 133, si no te permite hacer ese cambio es porque el motherboard no soporta ese procesador.

Saludos!

U have to find the motherbord's manual !!!! U will find there all u need. But most probably u won;t be able to put those processors (the speed diferences are too big, even if they are of the same slot type)

try resetting the bios or updating it
