NT (Linux/OpenBSD/NetBSD???) requires the "Windows > NT Alpha BIOS Firmware" on the motherboard. You can get the BIOS on either > the SX or LX motherboard. Also, the 21164PC doesn't have the 96KB L2 cache on-chip cache that the 21164 has, which makes for another reason for the lower performance of the 21164PC. > > Both of these are tons faster than a 300MHz Pentium II.
