If you are only using a single graphics card, then the BIOS will detect it as such and boot it up, irrespective of what you set the feature to. However, there may be a slight reduction in the time taken to detect and initialize the card if you select the proper setting for this BIOS feature. For example, if you only use a PCI Express graphics card, then setting Init Display First to PCIEx may speed up your system's boot-up process. Therefore, if you are only using a single graphics card, it is recommended that you set the Init Display First feature to the proper setting for your system (PCIEx for a PCI Express card and PCI Slot for a PCI card). However, if you are using multiple graphics cards, it is up to you to choose which card you want to use as your primary display card. It is recommended that you select the fastest graphics card as the primary display card. PCI Slot / PCIEx Reset Configuration Data If you install a new piece of hardware or modify your computer's hardware configuration, the BIOS will automatically detect the changes and reconfigure the ESCD (Extended System Configuration Data). Therefore, there is usually no need to manually force the BIOS to reconfigure the ESCD. However, the occasion may arise where the BIOS may not be able to detect the hardware changes. A serious resource conflict may occur and the operating system may not even boot as a result. This is where the Reset Configuration Data BIOS feature comes in. This BIOS feature allows you to manually force the BIOS to clear the prev iously saved ESCD data and reconfigure the settings. All you need to do is enable this BIOS feature and then reboot your computer. The new ESCD should resolve the conflict and allow the operating system to load normally. Please note that the BIOS will automatically reset it to the default setting of Disabled after reconfiguring the new ESCD. So, there is no need for you to manually disable this feature after rebooting Enabled / Disabled 3-26 http://www. tyan. com Tomcat i7221 S5150 Chapter 3: BIOS Setup Resources Controlled By When this option is set to AUTO, the BIOS by using ESCD, controls the IRQ and DMA assignments of all of the boot and PNP devices in the system. If you set this option to Manual, you will be able to manually assign all IRQ and DMA information. Auto (ESCD) / Manual PCI / VGA Palette Snoop This option is only useful if you use an MPEG card or an add-on card that makes use of the graphics card's Feature Connector. When enabled, it corrects incorrect color reproduction by "snooping" into the graphics card's frame buffer memory and modifying (synchronizing) the nformation delivered from the i graphics card's Feature Connector to the MPEG or add-on card. It also solves the problem of display inversion to a black screen after using the MPEG card. Disabled / Enabled PCI Device List Select disabled see BIOS configuration table easier.
