[. . . ] 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. User's Manual 3-20 Chapter3 Memory Hole At 15M-16M: Two options are available: Enabled and Disabled. This option is used to reserve the memory block 15M-16M for ISA adapter ROM. 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. Delayed Transaction: Two options are available: Enabled and Disabled. Set the option to enabled or disabled PCI 2. 1 features including passive release and delayed transaction for the chipset. 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. If you have an ISA card compatibility problem, you can try to enable or disable this option for optimal results. AGP Fast Write AGP Fast Writes are accelerated memory write transactions that occur when the AGP chipset supports Fast Writes and when both the AGP chipset and the display chipset are configured for Fast Writes. The Intel 820 chipset supports AGP Fast Write. Therefore, if your AGP card supports AGP Fast Write, you can set this item to Enabled. It can shorten the latency time between the AGP Bus command start and the AGP Bus data transfer, and then gives you better AGP write/transfer speed. AGP Aperture Size (MB): Seven options are available: 4 . This option specifies the amount of system memory that can be used by the AGP device. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. CX6 Introduction of the BIOS 3-21 3-5. Integrated Peripherals In this menu, you can change the onboard I/O device and other hardware peripheral settings. Figure 3-7. Integrated Peripherals Onboard IDE-1 Controller: The onboard IDE 1 controller can be set as Enabled or Disabled. The integrated peripheral controller contains an IDE interface with support for two IDE channels. If you choose Disabled, it will effect the settings of four items not available. For example, if you disabled the Onboard IDE-1 Controller, you will also disable the Master/Slave Drive PIO Mode and Master/Slave Drive Ultra DMA. Master/Slave Drive PIO Mode: Six options are available: Auto . The four IDE PIO (Programmed Input/Output) items let you set a PIO mode User's Manual 3-22 Chapter3 (0-4) for each of the four IDE devices that the onboard IDE interface supports. Modes 0 through 4 provide successively increased performance. [. . . ] How they serve you is also a good reference for your next purchase. 5. Contacting ABIT.
