Configuring memory shadow The system can configure the Memory Shadow options or you can manually set them. You can enable or disable shadowing of your system and video memory and control the specific blocks of ROM used for this purpose. Your computer can access RAM faster than ROM. The options on this screen allow your system to copy the contents of its system and/or video ROM into RAM. When you use shadowing, your system can perform certain operations faster, providing a significant increase in performance. Note For the best system performance, always set the System shadow and the Video shadow options to Enabled. If you enable shadowing for specific blocks, the ROM located in these blocks is copied to the shadow area. Configuring chipset registers The system can set your Advanced Chipset Control options or you can manually change the values in the chipset registers. setting these values correctly increases your system performance; however, setting them incorrectly may cause your system to malfunction or shut down. Be sure to set the Auto Configuration option to Enabled to let the system automatically configure these options to avoid problems. However, if you connected a scanner or a parallel port network adapter to your parallel port, you should set Auto Configuration to Disabled so you can change the Printer Port Control option to PS2 made (for bidirectional operation). The default setting for the parallel port is AT mode (for unidirectional operation). Setting Up Your System 1-13
