SUPER P6DLH and P6DLF support dual Pentium

II 233/266/300/
333 MHz processors. They are based on Intel’s 440 LX chipset
which enables Accelerated Graphics Port (AGP), Wake-on-LAN

,
SDRAM, concurrent PCI, and Ultra DMA 33 MB/s burst data transfer
rate. SUPER P6DLH is I

O-ready TM with a 66 MHz i960

RD I/O
processor built-in. AGP is disabled on SUPER P6DLH.
Both motherboards are Full AT size (13.2" x 12.2"). SUPER P6DLF
provides 5 PCI slots, 3 ISA slots and an Accelerated Graphics Port.
It accommodates a total of 1 GB EDO or 512 MB SDRAM memory
with 8 72-pin SIMMs or 4 168-pin DIMM sockets.
SUPER P6DLH provides 9 PCI slots and 3 ISA slots. It accommo-
dates a total of 1 GB EDO or 512 MB SDRAM. The I
2
O architecture
of SUPER P6DLH consists of a 66 MHz i960 RD I/O processor, an 8
Mb Flash I/O BIOS, and local IOP memory of up to 64 MB. The I
2
O
architecture 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 re-written for new operating system releases, drivers can be-
come more highly optimized and robust, improving performance
and reliability in mission-critical enterprise computing.
To attain portability across multiple operating systems and host
platforms, I
2
O drivers are divided into the OS Services Module
(OSM), and Hardware Device Module (HDM). The first module inter-
faces with the host operating system. The second interfaces with
the particular device, media or server managed by the driver. The
