[. . . ] But the next time you boot up, this option will automatically be set as Disabled. Computer Knowledge ESCD (Extended System Configuration Data) The ESCD contains the IRQ, DMA, I/O Port, Memory information of the system. This is a specification and a feature specific to Plug & Play BIOS. Resources Controlled By: When you select Auto, the BIOS will automatically assign the IRQ and DMA to PCI / ISA PnP . When this option is Manual, you can choose which IRQ or DMA can assign to PCI / ISA PnP . 3-20 Chapter 3 PCI IDE Card 2nd Channel: This option can be enabled or disabled. 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-slotX and ISA. ä PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE card inserted in. ä PCI-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. ä ISA: 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#). 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. Interuction of BIOS 3-21 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: ä Disable: No support for IR function. ä ASK IR (Amplitude Shift Keyed IR) mode. / IR Function Duplex: Set the IR mode as Half or Full. / RxD , TxD Active: 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. / Parallel Port Mode: Can be set as ECP, ECP+EPP, or Normal (SPP) mode. / 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. / EPP Mode Select: When the mode selected for the onboard parallel port is EPP, two EPP version options are available: EPP1. 7 or EPP1. 9 . 3-22 Chapter 3 On board IDE Controller: Onboard PCI IDE controller can be set as IDE-1, IDE-2, Both or Disable. [. . . ] Problem Description: Flash BIOS User Instructions G-1 Appendix G Flash BIOS User Instructions Example 1 To update BIOS and create a backup of the current system BIOS execute this command: AWDFLASH NEWBIOS /Py SAVEBIOS To update BIOS, create a backup of current system BIOS, and clear the CMOS, execute this command: AWDFLASH NEWBIOS SAVEBIOS /CC To update BIOS and clear PnP settings execute this command: AWDFLASH NEWBIOS /Sn /CP To make a backup of the current system BIOS execute the following command: AWDFLASH NEWBIOS /Pn SAVEBIOS /Sy Example 2 Example 3 Example 4 Notes: "NEWBIOS" indicates file name for the new BIOS which can be downloaded from our website at http://www. abit. com. tw (user can choose a different file name in place of NEWBIOS). "SAVEBIOS" indicates the filename of the old system BIOS (user can choose a different file name in place of SAVEBIOS). G-2 Explanation of parameter names: /CC: Clears CMOS data /CP: Clears PnP data Remarks: Appendix G ¬ When executing AWDFLASH. EXE, do not run HIMEM. SYS and EMM386. EXE in the CONFIG. SYS. - Please take the following actions to solve problems caused by power shortage or other other unpreventable malfunctions during BIOS update that lead to update failure. First, it is strongly suggested that you format a disk that can boot your computer before you update your BIOS. [. . . ]
