Computer Knowledge: SHADOW What is the SHADOW?The BIOS of standard video or interface cards is stored in ROM, and it is often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it into RAM. When the CPU runs this BIOS, the operation is speeded up. User's Manual 3-16 Chapter3 3-4. Chipset Features Setup Menu The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or is false, the motherboard will become unstable or you will not be able to boot up. If you don't know the hardware very well, use default values (i. e. use the LOAD SETUP DEFAULTS option). Figure 3-5. Chipset Features Setup You can use the arrow keys to move between the items. Use PgUP, PgDn, + or - key to change the values. When you have finished setting up the chipset, press ESC to go back to the main menu. SDRAM CAS latency Time: Two options are available: 2 and 3. You can select SDRAM CAS (Column Address Strobe) latency time according your SDRAM specification. SDRAM Precharge Control: Two options are available: Enabled and Disabled. This option specifies the length of the RAS precharge part of the DRAM system memory access cycle when SDRAM system memory is installed on the motherboard. ZM6 BIOS Setup 3-17 System BIOS Cacheable: You can select Enable or Disable. When you select Enabled, you get faster system BIOS executing speed via the L2 cache. Video BIOS Cacheable: You can select Enable or Disable. When you select Enabled, you get faster video BIOS executing speed via the L2 cache. Video RAM Cacheable: You can select Enable or Disable. When you select Enabled, you get faster video RAM executing speed via the L2 cache. You must check your VGA adapter manual to find out if any compatibility problems will occur. 8 Bit I/O Recovery Time: Nine options are available: NA è 8 è 1 è 2 è 3 è 4 è 5 è 6 è 7 èBack to NA. This option specifies the length of a delay inserted between consecutive 8 bit I/O operations. For an earlier 8 bit Add-on card, sometimes you need to adjust its recovery time to make it work normally. 16 Bit I/O Recovery Time: Five options are available: NA è 4 è 1 è 2 è 3 è Back to NA. This option specifies the length of a delay inserted between consecutive 16 bit I/O operations.
