system started after you turn it on. The BIOS
also manages data flow between the
computer's operating system and attached
devices such as the hard disk, video adapter,
keyboard, and mouse.
CAUTION:
The BIOS installed on your
Computer was loaded and tested with all
the devices initially installed in your
system. If you desire to have the BIOS
updated, consult TAG technical support in
advance as updates to your approved BIOS
may cause your system to become unstable
or inoperable.
6.3.1 Common BIOS Settings
6.3.1.1 Printer Parallel Port Uni., Bi-Directional, Disable,
Enable, ECP, EPP.
Settings in the CMOS enable you to configure
a parallel port to use Enhanced Parallel Port
(EPP) or Enhanced Parallel Port (ECP). ECP.
EPP and ECP are bi-directional standards,
operate in 8-bit, and allow data transfer speed
of approximately 2 MB/s. Some of the main
differences are that ECP supports Direct
Memory Access (DMA) and data compression,
which enables higher transfer rates.
It is also possible to completely disable the
parallel port in the BIOS. Most BIOS' allow you
to set the DMA channel, when the port mode is
set to ECP.
6.3.1.2 Com / Serial Port
Most personal computers have two serial ports.
In the BIOS you can assign
COM1/COM2/COM3/COM4 to serial port 1 or
2.
