Reset PnP Config Data:

If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings for the Plug & Play ISA Card and the PCI Card, select Enabled. But the next time you boot up, this option will automatically be set as Disabled.

Computer

ESCD (Extended System Configuration Data)

Knowledge

The ESCD contains the IRQ, DMA, I/O Port, Memory data of

 

all PnP cards, PCI cards and Onboard I/O. This is a specification

 

and a feature specific to Plug & Play BIOS.

PCI PnP BIOS Auto-Config:

This option enables or disables the BIOS capability to automatically assign IRQs. The BIOS default is Disable.

When you select Enable, the BIOS will automatically assign the correct IRQ to the interrupt number (INT#) of the PCI slots. When this option is disabled, you have to assign IRQs used by the interrupt number (INT#) of the PCI slots.

Xth Available IRQ:

You can select four IRQs out of the 10 listed (IRQ3, 4, 5, 7, 9, 10, 11, 12, 14, 15) to be assigned for use by the interrupt number (INT#) of the PCI slot.

1st Available IRQ:

This means that the first interrupt number (INT#) found on the PCI bus will use this IRQ. That is, this IRQ will be assigned to the first interrupt number (INT#) found on the PCI bus.

2nd Available IRQ:

This means that the second interrupt number (INT#) found on the PCI bus will use this IRQ. That is, this IRQ will be assigned to the second interrupt number (INT#) found on the PCI bus.

The third and the fourth available IRQ will be assigned in sequence to the third and the fourth interrupt numbers (INT#) found on the PCI bus.

PCI IDE Card 2nd Channel:

This option can be enabled or disabled. BIOS default is Enable.

Since this channel uses IRQ15, if you want to use this channel, you have to enable this option to make the BIOS assign IRQ15 to this channel.

PCI IDE Card IRQ Map to:

Three options are available for this item: PCI Auto, PCI-slotXand ISA.

äPCI-Auto:The onboard BIOSauto-detectswhich PCI slot has an IDE card inserted in.

Introduction of BIOS

3-25

äPCI-slotX:Some old PCI IDE cards cannot be detected by the BIOS. If the onboard BIOS cannot detect a PCE IDE card, you have to specify on which PCI slot the IDE card is inserted, to make the BIOS assign IRQ14 for use by the interrupt number (INT#) of this PCI slot.

äISA: If you select ISA, it means that your PCI IDE card features a “paddleboard” and a cable that can be connected to IRQ on the ISA slot, because the BIOS will not assign any IRQ to this PCI slot.

Attention:Primary Channel and Secondary Channel : The BIOS needs two independent interrupt number (INT#) lines to be allocated to the PCI IDE card. Be careful not to choose twice the same interrupt number (INT#).

Note: Since the interrupt number of the PCI slot is connected according the design described below, there are some limitations, be careful.

+The INT#A signal of the first PCI slot, the INT#B signal of the second PCI slot, the INT#C signal of the third PCI slot and the INT#D signal of the fourth PCI slot, are the same, so be careful not to use them simultaneously.

+The INT#B signal of the first PCI slot, the INT#C signal of the second PCI slot, the INT#D signal of the third PCI slot and the INT#A signal of the fourth PCI slot, are the same, so be careful not to use them simultaneously.

+The INT#C signal of the first PCI slot, the INT#D signal of the second PCI slot, the INT#A signal of the third PCI slot and the INT#B signal of the fourth PCI slot, are the same, so be careful not to use them simultaneously.

+The INT#D signal of the first PCI slot, the INT#A signal of the second PCI slot, the INT#B signal of the third PCI slot and the INT#C signal of the fourth PCI slot, are the same, so be careful not to use them simultaneously.

On Board USB Controller:

This is to Enable or Disable the onboard Universal Serial Bus (USB) controller.

Onboard PS/2 Mouse:

This is to Enable or Disable the PS/2 Mouse. When in Enable, IRQ 12 is used.

3-26

Chapter 3

On Board FDD Controller:

This is to Enable or Disable the Onboard FDD Controller.

On board Serial Port 1:

This is used to specify the I/O address and IRQ of Serial Port 1. Five options are available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4 or 2E8h/IRQ3.

On board Serial Port 2:

This is used to specify the I/O address and IRQ of Serial Port 2. Five options are available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4 or 2E8h/IRQ3.

Attention:Do not select the same I/O address and IRQ for the two serial ports, otherwise the serial ports will not be able to operate normally.

/ Onboard IR Function:

Onboard serial port 2 can support IR (Infrared) function. Three options are available:

äDisable: No support for IR function.

äIrDA (HPSIR) mode.

äASK IR (Amplitude Shift Keyed IR) mode.

/IR Duplex Mode:

Set the IR mode as Half or Full. Default is Half.

/ IR Tr/Re Polarity:

Set IR transmission/reception polarity as High or Low.

On board parallel Port:

Set the I/O address and IRQ of the onboard parallel port. Four options are available: Disable, 3BCh/IRQ7, 278h/IRQ5 and 378h/IRQ7. Default is 378h/IRQ7.

/ Parallel Port Mode:

Can be set as EPP v.1.7, EPP v. 1.9, ECP, ECP+EPP 1.7, ECP+EPP 1.9 or Normal (SPP) mode. Default is Normal (SPP) mode.

Introduction of BIOS

/ ECP Mode Use DMA:

When the mode selected for the onboard parallel port is ECP, the DMA channel selected can be Channel 1 or Channel 3.

OnBoard IDE-1Controller:

Onboard PCI IDE 1 controller can be set as Enable or Disable.

/Master drive PIO Mode:

äAuto: the BIOS can auto-detectthe PIO mode of the HDD in order to set its data transfer rate. (Default)

äMode 0~Mode 4: User can specify the PIO mode of the HDD in order to set its data transfer rate.

/Slave drive PIO Mode:

äAuto: the BIOS can auto-detectthe PIO mode of the HDD in order to set its data transfer rate. (Default)

äMode 0~Mode 4: User can specify the PIO mode of the HDD in order to set its data transfer rate.

OnBoard IDE-2Controller:

The onboard IDE-2controller can be set at Enable of Disable.

/Master drive PIO Mode:

äAuto: the BIOS can auto-detectthe PIO mode of the HDD installed in order to set its data transfer rate. (Default)

äMode 0~Mode 4: User can specify the PIO mode of the HDD in order to set its data transfer rate.

/Slave drive PIO Mode:

äAuto: the BIOS can auto-detectthe PIO mode of the HDD installed in order to set its data transfer rate. (Default)

äMode 0~Mode 4: User can specify the PIO mode of the HDD in order to set its data transfer rate.

Computer MODE 0~4 reflects the HDD data transfer rate. The higher theknowledge MODE value is, the better is the HDD data transfer rate. But it does not mean that you can select the highest MODE value just as you like, you first have to be sure that your HDD supports this MODE, otherwise the hard disk will not be able to operate

normally.

µ IDE HDD Auto Detection

After you have installed the hard disk, in old systems, you had to know the hard disk specifications, such as the number of cylinders, heads and sectors, and to enter the relevant information into the hard disk information section. If the CMOS data were erased, and you had forgotten the hard disk specifications, it was a great problem. But now, you can use this option to autodetect the hard disk type and specifications, and the BIOS will automatically detect all the relevant information and place them in the Hard Disk data section of the Standard CMOS Setup Menu, in order to allow you to use your hard disk.
