CHAPTER 1
SYSTEM OVERVIEW
OCTEK RHINO 5 is a powerful PC machine offering
unparalleled performance. The advanced external
cache system implemented meets the demand of the
most memory-intensive applications today. With the
Pentium processor and a high bandwidth 32-bit PCI
expansion bus, the I/O bottleneck that plagues most
PC systems is now removed.
All of the I/O is integrated inside the mainboard to
further facilitate system installation. The built-in IDE
can support up to 4 fast Enhanced IDE devices
whereas it can also support up to two floppy drives.
The mainboard also includes two serial ports and one
parallel port as the basic configuration for end user.
All that is needed is just a VGA card plugged into a
PCI or ISA slot to complete the whole system.
