The P6BXT-A+ is a full-sized ATX board measuring 305x220mm and using 4-layer printed circuit board. The P6BXT-A+ has a special design feature so that it includes a Slot-1 processor slot and a PPGA (Plastic Pin Grid Array) Celeron Socket-PGA370 processor socket. This feature means that you can install the mainboard with either a Pentium-III cartridge, a Pentium-II cartridge, the SEPP (Single Edge Processor Package) Celeron cartridge, or one of the new generation PPGA Celeron cartridges. In addition, the mainboard supports a 66 MHz memory bus, or a 100 MHz memory bus, so you can use inexpensive 66MHz memory chips, or higher-performance PC-100 memory chips. The board is installed with an integrated PCI-3D sound system and has a full suite of I/O ports. Seven expansion slots are available for system development and hardware monitoring is supported. This board allows complete flexibility. System integrators can choose the high-performance Slot -1 processor or the inexpensive PPGA Celeron processor according to the system requirements and the price/performance comparison of the two kinds of processor.
