EPP Mode Select

There are two versions of the EPP transfer protocol - EPP 1.7 and EPP 1.9. This BIOS feature allows you to select the ver- sion of EPP that the parallel port should use.

Generally, EPP 1.9 is the preferred setting because it sup- ports the newer EPP 1.9 devices and most EPP 1.7 devices; and offers advantages like support for longer cables. How- ever, because certain EPP 1.7 devices cannot work properly with an EPP 1.9 port, this BIOS feature was implemented to allow you to set the EPP mode to EPP 1.7 when such an issue ocurrs.

Therefore, it is recommended that you set this BIOS feature to EPP 1.9. But if you have trouble connecting to your parallel port device, switch to EPP 1.7. The choices are:

EPP1.9 / EPP1.7

ECP Mode Use DMA

This BIOS feature determines which DMA channel the paral- lel port should use when it is in ECP mode.

The ECP mode uses the DMA protocol to achieve data trans- fer rates of up to 2.5 Mbits/s and provides symmetric bidirec- tional communications. For all this, it requires the use of a DMA channel.

By default, the parallel port uses DMA Channel 3 when it is in ECP mode. This works fine in most situations.

This feature is provided just in case one of your add-on cards requires the use of DMA Channel 3. In such a case, you can use this BIOS feature to force the parallel port to use the alternate DMA Channel 1.

Please note that there is no performance advantage in choosing DMA Channel 3 over DMA Channel 1 or vice versa. As long as either Channel 3 or Channel 1 is available for your parallel port to use, the parallel port will be able to function properly in ECP mode. The choices are:

DMA1 / DMA3
