Introduction
1-1 Overview
The SUPER P6DGH supports dual Pentium II 233-450 MHz proces-
sors. This motherboard is based on Intel’s 440GX chipset, which
enables a 100 MHz system bus speed, an Accelerated Graphics
Port (AGP), Wake-on-LAN

, SDRAM, concurrent PCI and an Ultra
DMA 33 MB/s burst data transfer rate. In addition, the SUPER
P6DGH is I
2
O
−
ready with a built-in 66MHz Intel i960

RD I/O pro-
cessor.
The motherboard is Full AT size (13.2" x 12.2"). The SUPER P6DGH
provides 9 PCI slots, 2 ISA slots and an Accelerated Graphics Port.
It can accommodate a total of 2 GB registered DIMM or EDO sup-
ported (66Mhz), or 1 GB SDRAM memory with 4 168-pin DIMM sock-
ets.
AGP reduces contention between the CPU and I/O devices by broad-
ening the bandwidth of graphics to memory. It delivers a maximum
of 532 MB/s 2x transfer mode, which is quadruple the PCI speed!
The I
2
O architecture of the SUPER P6DGH consists of a 66 MHz
i960 RD I/O processor, an 8 Mb Flash I/O BIOS and local IOP
memory (optional) of up to 64 MB in 2 72-pin SIMMS. The I
2
O archi-
tecture provides a standard way to off-load the I/O functions from
the CPU, creating a direct I/O pipeline that no longer passes
through the host processor. Besides delivering increased system
performance, the I
2
O specification eliminates the need for different
drivers for each combination of operating system and SCSI or Net-
work Interface Card. Because the drivers may be standardized and
not rewritten for new operating system releases, they can become
more highly optimized and robust to improve performance and reli-
ability in mission-critical enterprise computing.
