Master PIO Mode

PIO refers to the concept of programmed input and output. Instead of the BIOS issuing an instruction sequence for initiating a data transfer from or to the hard disk, PIO enables the BIOS to notify the controller what task should be executed. The task is then fully handled by the controller and the CPU. Your system supports five PIO modes, 0 (standard) to 4, with the main difference relating to timing. If "Auto" (automatic) is selected, the BIOS will assess your drive and automatically specify the optimum PIO mode. Auto: The BIOS automatically sets the system value depending on the timing of your hard disk drive. Mode 0-4: You can select a mode suitable mode that matches the timing your hard drive.

Slave PIO Mode

IDEPrimary Master UDMA

This option is used to configure the Ultra-DMA/33 mode of your hard disk. Setting options: Auto, Enabled, Disabled. The option should be set to Enabled.

IDE Primary Slave UDMA

This option is used to configure the Ultra-DMA/33 mode of your hard disk. Setting options: Auto, Enabled, Disabled. The option should be set to Enabled.

IDE DMA Transfer access

This option is used to set the DMA transfer function of the IDE-hard disk. Options are: Enabled, Disabled.

IDE HDD Block Mode

This option is used to activate block mode for IDE hard disks. If your drive supports this mode and this option is activated, the system will read the number of blocks per request from the configuration sector of the hard disk. The recommended setting is Enabled, although it should be noted that this is not suitable for older hard disks.

Onboard Serial Port 1

Configuration of the serial interface settings: IRQ11 (used for the first serial port), Disabled (no interrupt is used). Setting options: Auto, 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 oder 2E8/IRQ3 ..

Onboard Serial Port 2

Configuration of the serial interface settings: IRQ10 (used for the second serial port), Disabled (no interrupt is used). Setting options: Auto, 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 oder 2E8/IRQ3..

UART Mode Select

Mode for driver of the serial interface:

normal for RS-232 serial interface
ASKIR for Amplitude keyed shift interface for IR devices
IrDA for IrDA-interface

RxD, TxD Active

Settings cannot be changed in standard mode. This option is used for setting IR transmission/reception to High or Low.

IR Transmission Delay

If this option is activated, transmission is delayed. Setting options: Enabled, Disabled.

UR2 Duplex Mode

This option is used for configuring infrared devices. Setting options: Full or Half. Please refer to the IR device manual regarding the duplex mode setting.

Use IR Pins

This option is identical to the TxD, RxD Active option. The required information can be found in the documentation for your IR device.

Watch Dog Timer Select

Here the timer for the watchdog will be set: Disabled, 10 Sec, 20 Sec, 30 Sec, 40 Sec, 1 Min, 2 Min,4 Min)

Onboard Serial Port 3

Configuration of the serial interface settings: IRQ11 (used for the third serial port), Disabled (no interrupt is used). Setting options: Auto, 3F8/IRQ11, 2F8/IRQ11, 3E8/IRQ11 oder 2E8/IRQ11 .

Onboard Serial Port 4

Configuration of the serial interface settings: IRQ11 (used for the fourth serial port), Disabled (no interrupt is used). Setting options: Auto, 3F8/IRQ10, 2F8/IRQ10, 3E8/IRQ10 oder 2E8/IRQ10.
