notes Notes

This is a motherboard from another manufacturer ( a custom board assembler ), which ASUS (Taiwan) gave permission to produce ASUS boards due to the earthquake in Taiwan, but due to minor changes in the board assembly, it was renamed from P2B to OPBX-4

Certain revision 1.10 boards supports Coppermine Pentium III and Celeron due to having a newer voltage regulator. Socket 370 CPUs are officially supported with an Sloket. FSB 133 CPUs are supported via overclocking.
