To attain portability across multiple operating systems and host
platforms, I

O drivers are divided into the OS Services Module (OSM)
and the 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
two modules interface with each other through a two-layered com-
munications system. A Message Layer sets up a communications
session and a Transport Layer defines how information will be
shared. The Message Layer resides on the Transport Layer.
The i960 RD I/O processor (IU20) is a highly integrated, intelligent
I/O subsystem on a chip. Mode 3 is the default setting for normal
I

O operation. The i960 RD has two main functions. As a local
processor, it off-loads interrupt-intensive I/O tasks from the host
CPU. Its architecture is composed of a RISC core surrounded by
peripherals essential to the I/O function. The onboard PCI-to-PCI
bridge enables designers to connect I/O components directly to the
PCI bus and to also add additional PCI slots. The bridge improves
overall system performance by reducing bus traffic.
Wake-on-LAN allows for remote network management and configu-
ration of the PC, even in off-hours when the PC is turned off. This
reduces the complexity of managing the network.
Other features that maximize simplicity in managing the computer
are PC 98-ready and support for an Advanced Configuration and
Power Interface (ACPI). W ith PC Health Monitoring, you can protect
your system from problems before they even occur.
Included in the I/O are 2 EIDE ports, a floppy port, an ECP/EPP
parallel port, a PS/2 mouse port, 2 serial ports (including an infra-
red port) and 2 USB ports. The SUPER P6DGH has an onboard
Adaptec 7896 dual-channel Ultra II LVD (Low Voltage Device) SCSI
controller with a data transfer rate of up to 80 MB/s. This supports
the Adaptec ARO-1130CA2 RAIDport III card for increased I/O per-
formance and fault tolerance. The boards come with a CD that
includes such software utilities as the SUPERMICRO PIIX4 Upgrade
