[. . . ] 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. BM6 BIOS Setup 3-17 DRAM Data Integrity Mode: Two options are available: Non-ECC or ECC. This option is used to configure the type of DRAM in your system. ECC is Error Checking and Correction, when your memory is ECC memory, choose the ECC option. 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. For an earlier 16 bit Add-on card, sometimes you need to adjust its recovery time to make it work normally. Memory Hole At 15M-16M: This option is used to free up the memory block 15M-16M. Some special peripherals need to use a memory block located between 15M and 16M, and this memory block has a size of 1M. We recommend that you disable this option. User's Manual 3-18 Chapter3 Passive Release: Two options are available: Enabled and Disabled. Set the option to enabled or disabled passive release for the Intel PIIX4 chip (Intel PCI to ISA bridge). This function is used to meet the latency of the ISA bus master, if you have an ISA card compatibility problem, you can try to enable or disable this option for optimal result. Delayed Transaction: Two options are available: Enabled and Disabled. Set the option to enabled or disabled delayed transaction for the Intel PIIX4 chip. This function is used to meet the latency of PCI cycles to or from the ISA bus. This option must be enabled to provide PCI 2. 1 compliance. [. . . ] MODEL: Note the model number given in your user's manual. Motherboard model number (REV): Note the motherboard model number labeled on the motherboard as "REV:*. **". BIOS ID and Part Number: See next page example. * * BM6 Troubleshooting (Need Assistance?) D-3 4. DRIVER REV: Note the driver version number indicated on the DEVICE DRIVER disk (if have) as "Release *. **". [. . . ]
