[. . . ] Video BIOS loads into the C0000-C7FFF memory area when video shadowing is enabled. If an expansion peripheral in your system contains ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM. Shadowing improves the firmware's performance because the firmware can be read by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit XT bus. However, shadowing also results in reducing the amount of high memory (640 KB to 1 MB) for loading device drivers. Shadowing is used mostly for ROM chips on ISA cards and not for PCI cards. Shadowing and playing games at the same time may result in system instability as some games access the RAM memory area being shadowed. 27 User's Manual 3-3 Advanced Chipset Features By choosing the Advanced Chipset Features option from the CMOS Setup Utility menu (Figure 3-1), the screen below is displayed. This sample screen contains the manufacturer's default values for the mainboard.

Explanation of the DRAM timing and chipset features setup is lengthy, highly technical and beyond the scope of this manual. Below are abbreviated descriptions of the functions in this setup menu. You can look on the world wide web for helpful chipset and RAM configuration information including AWARD's web site at http://www. award. com. A. BANK 0/1, 2/3 & 4/5 DRAM Timing This item allows youto select the value in this field, depending on whether the board has paged DRAM or EDO (Extended Data Output) DRAMs. B. SDRAM Cycle Length When synchronous DRAM is installed, the number of the clock cycles of CAS latency depends on the DRAM timing. Do not reset this setting from the default value specified by the system designer. 28 Award BIOS Setup Program C. Memory Hole at 15M-16M Enabling this function will reserve the memory address space between 15MB and 16MB for ISA expansion cards. However, enabling this function will result in not allowing the system to have access to memory above 16MB. Please note that some expansion cards require this setting to be enabled. If Auto Configuration is enabled, you must set the DRAM timing function to 60ns or 70ns, depending on the type of DRAM you install. D. System BIOS Cacheable Enabling this function allows caching of the system BIOS ROM at F0000hFFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Caching the system BIOS results in better performance than shadowing the system BIOS as discussed in Section 3-2. E. Video RAM Cacheable Enabling this function will allows caching of the video RAM, resulting in better system performance. [. . . ] Selet Defragmenter by pressing Alt+F3 key. You will be prompt to confirmed defragment your drive. Wait for the defrgmentation process to finish and the system will automatically reboot. Upon system boot up, the HDD Instant Recovery Utility will be shown on the screen. [. . . ]
