Powers of two? Bit operations in BIOS?
0,1,2,4 makes a lot more sense than what my Intel board does:
CPU0: Intel Pentium Pro stepping 07
CPU12: Intel Pentium Pro stepping 07
0 and 12?!?
My Tyan board does the much more sensible combination:
CPU0: Intel Pentium MMX stepping 03
CPU1: Intel Pentium MMX stepping 03
