I've found no markings on the board that identify it as any particular brand. }Also notice that "An SMP kernel will ONLY run on an Intel MP }spec. qualified motherboard" and "Be sure to disable 'cpu }I386_CPU' && }'cpu I486_CPU' for SMP kernels." (The latter may not be required for }your version, but won't hurt in any case). already done. } }Also, check the stepping number of the P2's (on the chip, somewhere, }one hopes, or possibly in dmesg when the system boots) and then check }the intel web to make sure the two chips will work *together*. While }each may work fine, if you've don't have compatible stepping numbers, }they won't work together. } }
