Chapter 1: Introduction
UIO
The NovaScale R423 serverboard is a specially-designed serverboard that features
UIO (Universal I/O) technology. UIO serverboards have a PCI-Express x8 con-
nector that can support any one of several types of UIO card types (low-profi le
only) to add SAS ports, additional LAN ports, etc. to the serverboard. This allows
the user to tailor the serverboard to their own needs. Note: the NovaScale R423
does not come with a UIO card pre-installed.
Onboard Controllers/Ports
One fl oppy drive connector and two onboard ATA/100 connectors (one reserved
for the use of a compact fl ash card) are provided to support IDE hard drives or
ATAPI devices. The color-coded I/O ports include one COM port (an additional COM
header is located on the serverboard), a VGA (monitor) port, two USB 2.0 ports
(three additional USB headers are included on the serverboard), PS/2 mouse and
keyboard ports and two gigabit Ethernet ports.
ATI Graphics Controller
The NovaScale R423 serverboard features an integrated ATI video controller based
on the ES1000 32 MB graphics chip. The ES1000 was designed specifi cally for
servers, featuring low power consumption, high reliability and superior longevity.
Other Features
Other onboard features that promote system health include onboard voltage moni-
tors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU
overheat sensors, virus protection and BIOS rescue.
