SPP/EPP/ECP/ECP+EPP
To operate the onboard parallel port as Standard Parallel Port only, choose “SPP.” To
operate the onboard parallel port in the EPP modes simultaneously, choose “EPP.” By
choosing “ECP”, the onboard parallel port will operate in ECP mode only. Choosing
“ECP+EPP” will allow the onboard parallel port to support both the ECP and EPP modes
simultaneously. The ECP mode has to use the DMA channel, so choose the onboard
parallel port with the ECP feature. After selecting it, the following message will appear:
“ECP Mode Use DMA” at this time, the user can choose between DMA channels 3 to 1.
The onboard parallel port is EPP Spec. compliant, so after the user chooses the onboard
parallel port with the EPP function, the following message will be displayed on the screen:
“EPP Mode Select.” At this time either EPP 1.7 spec. or EPP 1.9 spec. can be chosen.

IDE DMA transfer access
The integrated peripheral controller contains an IDE interface with support for one IDE
channels. Select Enabled to activate each channel separately. The settings are: Enabled and
Disabled.
Primary Master/Slave PIO
The two IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-2) for each of
the two IDE devices that the onboard IDE interface supports. Modes 0 through 2 provide
successively increased performance. In Auto mode, the system automatically determines the
best mode for each device. The settings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode
4.
