3-14 CHAPTER 3
Onboard UART 2 Mode:
The default value is standard. This field allows the User to
select the COM2 port that can support a serial Infrared Interface.
Standard:
Support a Serial Infrared Interface IrDA.
HPSIR:
Support a HP Serial Infrared Interface format.
ASKIR:
Support a Sharp Serial Infrared Interface format.
Onboard Parallel port:
This field allows the user to sellect the LPT port. The default
value is 378H/IRQ7.
378H
:
Enable Onboard LPT port and address is 378H and IRQ7
278H
:
Enable Onboard LPT port and address is 278H and IRQ5.
3BCH
:
Enable Onboard LPT port and address is 3BCH and IRQ7.
Disabled
:
Disable Onboard SMC CHIP's LPT port.
Parallel port Mode:
This field allows the user to sellect the parallel port mode.
The default value is ECP+EPP.
Normal
:
Standard mode. IBM PC/AT Compatible bidirectional parallel port.
EPP
:
Enhanced Parallel Port mode.
ECP
:
Extended Capabilities Port mode.
EPP+ECP
:
ECP Mode & EPP Mode.
ECP Mode USE DMA:
This field allows the user to sellect DMA1 or DMA3 for
the ECP mode. The default value is DMA3.
DMA1
:
The filed selects the rounting of DMA1 for the ECP mode.
DMA3
:
The filed selects the rounting of DMA3 for the ECP mode.
NOTE
: Parallel Port address is 378H/3BCH that selects the rounting of IRQ7 for LPT1.
Parallel Port address is 278H that selects the rounting of IRQ5 for LPT1.

LOAD SETUP DEFAULTS
The
"
LOAD SETUP DEFAULTS
" function loads the system default data directly
from ROM and initializes the associated hardware properly. This function will be
necessary only when the system CMOS data is corrupted.
