[. . . ] The contents of the video ROM area from C000h-C7FFFh are copied from ROM to RAM and can be written to or read from cache memory. BIOS The Optimal and Fail-Safe default settings are Cached. C800, 16K Shadow; CC00, 16K Shadow; D000, 16K Shadow; D400, 16K Shadow; D800, 16K Shadow; and DC00, 16K Shadow These options enable shadowing of the contents of the ROM area named in the option. The ROM area not used by ISA adapter cards is allocated to PCI adapter cards. The settings are: Setting Disabled Enabled Cached Description The contents of the video ROM are not copied to RAM. The contents of the video ROM area from C000h-C7FFFh are copied (shadowed) from ROM to RAM for faster execution. The contents of the video ROM area from C000h-C7FFFh are copied from ROM to RAM and can be written to or read from cache memory. The Optimal and Fail-Safe default settings are Cached. 37 Chapter 4 Chipset Setup Choose Chipset Setup on the AMIBIOS Setup main menu. USB Function Set this option to Enabled to enable USB (Universal Serial Bus) support. USB Keyboard/Mouse Legacy Support Set this option to Enabled to enable support for older keyboards and mouse devices if the USB Function option is set to Enabled. EDO DRAM Speed (ns) This option specifies the RAS Access Time in nanoseconds for the EDO DRAM system memory installed in this computer. The settings are Auto (AMIBIOS automatically determines the RAS access Time parameter), Manual, 50, 60, or 70. EDO Read Burst Timing This option specifies the timings for EDO DRAM system memory for Read operations in burst mode. EDO Write Burst Timing This option specifies the timings for EDO DRAM system memory for Write operations in burst mode. Setting this switch incorrectly may result in system failure. 38 EDO RAS Precharge This option specifies the length of the RAS precharge part of the DRAM system memory access cycle when EDO DRAM system memory is installed in this computer. EDO RAS To CAS This option specifies the length of the delay inserted between the RAS and CAS signals of the DRAM system memory access cycle when EDO DRAM system memory is installed in this computer. MA Wait State This option specifies the length of the delay inserted between MA signals. SDRAM Timing Latency This option specifies the latency for the Synchronous DRAM system memory signals. The settings are Auto (AMIBIOS automatically determines the optimal delay) or Manual. RAS To CAS This option specifies the length of the delay inserted between the RAS and CAS signals of the DRAM system memory access cycle. The Optimal and Fail-Safe default settings are 3 CLKs. BIOS 39 Chapter 4 RAS Precharge This option specifies the length of the RAS precharge part of the DRAM system memory access cycle when EDO DRAM system memory is installed in this computer. VGA Frame Buffer USWC Set this option to Enabled to enable the VGA video frame buffer using USWC (Uncacheable, Speculatable, Write-Combined) memory. Older ISA VGA card drivers may not behave correctly if this option is not set to Disabled. PCI Frame Buffer USWC Set this option to Enabled to enable the USWC memory attribute and improve video performance when a PCI video adapter is installed.
