BIOS Setup
UART2 Mode Select
This field is used to select the type of IrDA standard supported by
your IrDA device. For better transmission of data, your IrDA
peripheral device must be within a 30
o angle and within a distance
of 1 meter.
UART2 Duplex Mode
Half Data is completely transmitted before receiving data.
Full Transmits and receives data simultaneously.
Onboard Parallel Port
378/IRQ7, 3BC/IRQ7, 278/IRQ5 Selects the I/O address and
IRQ for the onboard parallel port.
Disabled Disables the onboard parallel port.
Parallel Port Mode
The options are SPP, EPP, ECP and ECP+EPP. These apply to a
standard specification and will depend on the type and speed of
your device. Refer to your peripheral’s manual for the best option.
SPP
Allows normal speed operation but in one direction only.
“ECP (Extended Capabilities Port)”
Allows parallel port to operate in bidirectional mode and at a
speed faster than the normal mode’s data transfer rate.
“EPP (Enhanced Parallel Port)”
Allows bidirectional parallel port operation at maximum speed.
ECP Mode Use DMA
This is used to select a DMA channel of the parallel port.
