In addition to the above, I should remind you that early revision P2B boards do not natively support Coppermine which has lower voltage than Katmai (~1.7V vs ~2.0V, just check the docs or the guide above). However you can bypass this limitation if you're using FCPGA CPU + slotket with its own voltage regulator (MSI MS-6905 ver 2.x should do, there are lots of it but currently not listed on ebay). Otherwise with slot 1 CPUs you're limited to 600MHz Katmai max.

IIRC only from P2B rev 1.12 that you can be sure Coppermine is supported out of the box (officially, the 100FSB versions).
Note that P2B-F is another variant with extra PCI slot and different revision scheming to the regular P2B. While the P3B-F comes in 6 PCI / 1 ISA and 5 PCI / 2 ISA versions -- as well as a 6 PCI without ISA slot.
Finally -- Yes, the P3B-F a 1999 release!

If you want 1999 native 133 FSB you'll have to go with i820 (i815 came a bit too late!).
I have rev 1.04 P3B-F with a 800EB (133) but sometimes it has to reboot before a successful POST.
