No, you cannot.
Yes.
I've yet to encounter an AT motherboard that supported a Pentium III processor. All the same, it is possible to run Solaris 10 on a Pentium III computer. You'll need at least 256 MB of RAM, however.
The Intel Pentium III was released on February 26, 1999.
Yes.
Yes. The GA-6BXC can support any Slot 1 Intel Pentium II or Pentium III processor. For the faster Pentium IIIs, you will need to purchase a "slotket" to convert a Socket 370 processor to the Slot 1 interface.
The Intel Pentium Dual-Core is much faster.
They are no longer manufactured.
No, the Pentium 3 and Pentium 4 are not only samples of 2 completely different architectures, but also use a different socket so a change between the 2 on the same motherboard is impossible.
The L1 cache in the Pentium III is SRAM.

No. It is much more powerful.
As long as the motherboard has a compatible expansion slot, yes.
