Readme File =========== This file contains additional information to supplement the manual. Please read all the sections before you proceed with the installation of your PCI card. 1. Changing the Interrupt Request (IRQ) Setting 1. CHANGING THE INTERRUPT REQUEST (IRQ) SETTING ============================================ If you want to change an IRQ setting for a PCI card, it is best to do so from the BIOS setup screen. The reason: PCI cards are configured differently from ISA cards; unlike ISA cards, it is usually not possible to change the IRQ for a PCI card from the operating system. ------------------------------------------------------------------ CAUTION: Do not change the BIOS settings unnecessarily unless you are skilled in it, as meddling with the BIOS settings may hang the system or slow down the system performance. Record all BIOS settings prior to making any changes to ensure you can return to your original settings. ------------------------------------------------------------------ To access the BIOS setup screen: a. At system startup, press the key or key combination (often just the Delete or Esc key) as required by your motherboard. NOTE: For more directions on entering your BIOS and an explanation about what each BIOS setting means, refer to your motherboard manual. The IRQ resource is typically found in the PNP/PCI Configuration Setup section. Under this section, there is an option to assign PCI slots to "Auto" or "Manual" to set an IRQ. This option is typically called Resources Controlled By or PNP/PCI BIOS Auto-Config. To change an IRQ, you need to set this option to "Manual" or "Disabled". Some BIOSes only allow you to define which IRQs are not to be used and will in turn assign another available IRQ automatically, while some BIOSes allow you to select the IRQs to be used for a particular PCI slot. For example, with a certain type of BIOS: To change the IRQ setting for your PCI card from the current IRQ 11: a. At Resource Controlled By option, switch to "Manual". b. Change the setting in IRQ-11 option to "Legacy ISA". This means that the BIOS will assign an available IRQ other than IRQ 11 to the PCI audio card. c. Save these new settings and exit the BIOS. Another example on a different type of BIOS: If your PCI audio card is plugged into slot 1, your PCI video card in slot 3, and both cards are using IRQ 11, to change the IRQ setting for your PCI audio card from current IRQ 11: a. At the BIOS Auto-Config option, switch to "Disabled". b. Change the setting in slot 1 option to another available interrupt. c. Save these new settings and exit the BIOS. NOTE: For more information on BIOS setting or Slot 1 location, refer to your BIOS or motherboard manual. *** End of Readme ***
