3.3V Memory Module Sockets (DIMM)
The Mainboard provides three 168 pin standard DIMM sockets
for installation of 3.3V unbuffered Single or Double Bank
SDRAM modules.
G
Serial COM1, Serial COM2 and Parallel Port Connector's
The
ATX
Mainboard provides two serial port connector's and
one parallel port connector. Based on the ATX standard, (2) 9-
pin serial ports and (1) 25-pin parallel port are now built on the
mainboard back panel. This design makes your mainboardts
installation easier. The parallel port can be BIOS configured into
standard (SPP) mode, Enhanced Parallel Port (EPP) mode, and
a high speed Extended capabilities Port (ECP) mode. EPP
Mode requires a driver provided by the peripheral manufacturer
in order to operate properly.
The
AT
Mainboard provides two 10-pin serial ports and one 26-
pin parallel port pin Headers for Cable are now built on the
mainboard.
H
Accelerated Graphics Port (AGP) Connector
The Mainboard provides an AGP slot compatible with the
Accelerated Grahics Port specification. AGP compliant video
cards offer a much higher throughput than equivalent PCI bus
video cards. PCI currently only supports a 33 Mhz bandwidth,
and can transport at peak rates up to 133 MB/s over its 32 bit
data bus. AGP operates at a 66 Mhz bandwidth which enables
a peak rate of 266 MB/s in what is known as ‘X1’ mode. Using
‘X2’mode, the peak transport rate can go as high as 532 MB/s.
I
LITHIUM BATTERY
A 3V, CR-2030, Lithium battery is installed on the on-board
battery socket. This battery is sued to supply the CMOS RAM
backup power during system powered-off. Danger of explosion
if battery is incorrectly replaced. Therefore, if you have any
difficulties, please consult to the technical personnel.
