    Data bus width 64 bits
    Address bus width 32 bits
    DMA channels

    Yes, you can put any Slot 1 P3/Celeron in there. 133MHz FSB CPUs will run at 100MHz (1/4 slower).

    You will not be able to put any tualatin-based CPU in that system unless you get a slotket, but any coppermine-core or mendocino-core would operate just great.

    If you are really lucky, you can get your hands on a socket or slot coppermine p3 1000 with a 100MHz FSB. That'll give you a 1GHz machine, though I wouldn't spend more than $100 on it since the machine itself is so old.

    Often a BIOS that old will not be able to recognize the CPUs properly. Don't worry. So long as it is operating at the proper frequency and the board is able to deliver the lower voltage of the P3, it will work fine.

    thanks..thats encouraging..i was just having a look on ebay and saw this one
    Intel PIII

    Slot 1 Processor 1GHz (1000MHz)

    1000/256/133/1.7V S1



    FOXCONN Heatsink (P/N: 210720-001 B)

    will it work? and if if it does will it be at 600 mhz as is is a 133.
    Thanks a lot.

    Provided your board can supply ~1.7V, it should run fine, but yes, it will be operating at 600MHz instead of 1000

    You may be better off looking for a 600MHz or 900MHz Coppermine-based Celeron.

    u mean a 100mhz fsb celeron? not many 100mhz ones available on ebay.
    why do u suggest the celerons are better?
