Introduction
This mainboard has a slot-1 processor socket for an Intel
processor cartridge, and it also has a socket-370 for an Intel
PPGA (Plastic Pin Grid Array) Celeron processor. You can
install either one of these processors according to the power and
performance requirements that you need from your system. Note
that you cannot install two processors on this mainboard.
Slot-1 processors include the SEPP (Single Edge Processor
Package) Celeron, t e Pentium-II, and t e Pentium-III. Clock
rates run as high as 550 MHz. Socket- 70 processors are the
PPGA Celeron which runs at clock rates up to 466 MHz. The
mainboard supports a system bus of 66 MHz or 100 MHz.
The mainboard uses the Xcel 2000 chipset which provides CPU
Plug & Play through firmware. The mainboard is highly integrated
and includes a built-in 64-bit AGP Grap ics Accelerator, a built-
in PCI 3D Sound System, and a built-in 10BaseT/100BaseTX
Network Adapter. A V.90 Fax/modem DAA module is also
shipped with the mainboard. In addition, it has a full set of ATX I/
O Ports including a serial port, one PS/2 ports, a parallel port and
two USB ports.
This mainboard has all the features you need to develop a powerful
multimedia workstation that is network ready, and has built-in
communications. The board is baby-AT sized and has power
connectors for ATX and AT power supply units and it can be
installed in AT system case.
