The CB650M-BX motherboard integrates the latest advances in pro c e s s o r,
m e m o r y, and I/O technologies into a Micro ATX form factor(244x205mm) that
combines performance, flexibility, and easy of use into high integrated capable
of meeting a variety of price/performance levels.

The CB650M-BX motherboard supports Intel Pentium II/III processor or
C e l e ron processor based on the Intel 440BX AGPsets(82443BX and 82371EB).
The CB650M-BX motherboard supports not only a 66MHz host but also a
100MHz host bus. So Intel Pentium II/III 350~450MHz processor and
Pentium II/III(Katmai) processor with a 100MHz host bus can be supported
for higher performance level. Two standard 168-pin DIMM Sockets with
memory size up to 256MB support Synchronous DRAM memory.

The Intel 82371EB PCI-to-ISA/IDE Xcelerator(PIIX4E) provides an integrated
Bus Master IDE controller and Ultra DMA/33 with high performance IDE
interfaces for up to four devices.

In addition, the CB650M-BX comes with an AGP(Accelerated Graphics Port)
bus slot, a faster than the current 33MHz PCI bus. The AGP bus provides a
d i rect connection between graphics subsystem and system memory.
