[. . . ] Security Option: BIOS This category allows you to limit access to the System and Setup, or just to Setup. System: The system will not boot and the access to Setup will be denied if the correct password is not entered at the prompt. Setup: The system will boot; but the access to Setup will be denied if the incorrect password is not entered at the prompt. PCI/VGA Palette Snoop: This field controls the ability of a primary PCI VGA controller to share a common palette (When a snoop write cycles) with an ISA video card. Enabled: If an ISA card is connected to a PCI VGA card via the VESA connector, and that ISA card connects to a VGA monitor, then that ISA card uses the RAMDAC of the PCI card. OS Select For DRAM > 64MB: Some operating systems require special handling. OS2: Select this if you are running the OS/2 operating system with greater than 64MB of RAM. Non-OS2: Select this for all other operating systems and configurations. Video BIOS Shadow: This option allows video BIOS to be copied into RAM. Disabled: Video shadow is disabled. Page 4-7 BIOS C8000 - CBFFF Shadow: CC000 - CFFFF Shadow: D0000 - D3FFF Shadow: D4000 - D7FFF Shadow: D8000 - DBFFF Shadow: DC000 - DFFFF Shadow: MS7132A These categories determine whether ROMs from option cards will be copied into RAM. This will be in 16K byte or 32K byte units, and the size will depend on chipset of the option card. Disabled: Optional shadow is disabled. 4-3 Chipset Features Setup Choose the "CHIPSET FEATURES SETUP" in the CMOS SETUP UTILITY menu to display following menu.

SDRAM Bank Interleave: The item allows you to set how many banks of SDRAM support in your mainboard. DRAM Page-Mode: The item will active or inactive chipset page registers. DRAM Fast Decoding: The item will effective DRAM operation sequential. DRAM Read Option: The item will effective DRAM reading CMD sequential. Memory Hole: You can reserve this memory area for the use of ISA adaptor ROMs. Enabled: This field enables the main memory (15~16MB) to remap to ISA BUS. Note: If this feature is enabled you will not be able to cache this memory segment. Page 4-9 BIOS MS7132A Read Around write: DRAM optimization feature: If a memory read is addressed to a location whose latest write is being held in a buffer contents, and the read is not sent to the DRAM. The Choice: Enabled, Disabled Concurrent PCI/Host: When disabled, CPU bus will be occupied during the entire PCI operation period. The Choice: Enabled, Disabled System BIOS Cacheable: As with caching the Video BIOS above, enabling this selection allows accesses to the system BIOS ROM addressed at F0000H-FFFFFH to be cached, provided that the cache controller is enabled. The Video BIOS cache will cause access to video BIOS addressed at C0000H to C7FFFH to be cached, if the cache controller is also enabled The Choice: Enabled, Disabled.
