4 BIOS Setup Utility

Chipset Features Setup

This section allows you to configure the system based on the specific features of the installed chipset. The chipset manages bus speeds and access to system memory resources, such as DRAM and the L2 external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. These items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system.

DRAM Timing

The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The DRAM timing should match the speed of the slowest installed memory. For instance, if 60 ns SIMMs are installed on the RASCard, you should set this item to 60 ns. But if you install both 60 ns and 70 ns SIMMs, you should change it to 70 ns.

System BIOS Cacheable

When this item is enabled, accesses to the system BIOS ROM addressed at F0000H- FFFFFH are cached, provided that the cache controller is enabled.

Enabled

BIOS access cached.

Disabled

BIOS access not cached (Default).
