[. . . ] PCI 2. 1 Support (Enabled) This function allows you to enable or disable PCI 2. 1 features including passive release and delayed transaction. Leave Enabled (default setting) for PCI 2. 1 compliancy. Memory Hole At 15M­16M (Disabled) Enabling this feature reserves 15MB to 16MB memory address space to ISA expansion cards that specifically require this setting. This makes the memory from 15MB and up unavailable to the system. Expansion cards can only access memory up to 16MB. DRAM are xx bits wide If all your DIMMs have ECC (e. g. , 8 chips + 1 ECC chip), they are considered 72bits and the following will be displayed: IV. BIOS Chipset Features 43 If your DIMMs do not have ECC (e. g. 8 chips), they are considered 64 bits and the following will be displayed instead: Data Integrity Mode (Non-ECC) Non-ECC has byte-wise write capability but no provision for protecting data integrity in the DRAM array. EC-Only data errors are detected but not corrected. ECC with hardware scrubbing allows a detection of single-bit and multiple-bit errors and recovery of single-bit errors.

IDE 0 Master/Slave PIO/DMA Mode, IDE 1 Master/Slave PIO/DMA Mode (Auto) Each channel (0 and 1) has both a master and a slave making four IDE devices possible. Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4), it is necessary for these to be independent. The default setting of Auto will allow autodetection to ensure optimal performance IV. BIOS Chipset Features 44 ASUS X5LJV User's Manual IV. BIOS SOFTWARE Power Management Setup This "Power Management Setup" option allows you to reduce power consumption. This feature turns off the video display and shuts down the hard disk after a period of inactivity. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Power Management Setup IV. BIOS Power Management 45 Power Management (User Define) This field acts as the master control for the power management modes. Max Saving puts the system into power saving mode after a brief period of system inactivity; Min Saving is almost the same as Max Saving except that this time the system inactivity period is longer; Disable disables the power saving features; User Define allows you to set power saving options according to your preference. IMPORTANT: Advanced Power Management (APM) should be installed to keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to add the statement, DEVICE=C:\DOS\POWER. EXE, in you CONFIG. SYS. For Windows 3. x and Windows 95, you need to install Windows with the APM feature.
