Onboard Serial Port2
This option enables serial port 2 on the motherboard and specifies the base I/O port address for serial port 2. The settings are Auto. Disabled, 3F8h, 2F8h, 3E8h, 2E8h. The
Onboard Parallel Port
This option enables the parallel port on the motherboard and specifies the parallel port base I/O port address. The settings are Auto, disabled, 378, 378, 3BC. The
Parallel Port Mode
This option specifies the parallel port mode. ECP and Epp are both bidirectional data transfer sechemes that adhere to the IEEE P1284 specification. The settings are:
Setting | Description |
Normal | The normal parallel port mode is used. This is the |
| default setting. |
|
|
EPP | The parallel port can be used with devices that |
| adhere to the Enhanced Parallel Port (EPP) specifi- |
| cation. EPP uses the exiting parallel port signals to |
| provide asymmetric bidirectional data transfer |
| driven by the host device. |
|
|
ECP | The parallel port can be used with devices that |
| adhere to the Extended Capabilities Port (ECP) |
| specification. ECP uses the DMA protocol to |
| achieve transfer rates of approximately 2.5 Mbs. |
| ECP provides symmetric bidirectional communla- |
| tions. |
