MS-6775 ATX Mainboard

Password Check

This specifies the type of AMIBIOS password protection that is implemented. Setting options are described below.

Option	Description
Setup	The password prompt appears only when end users try to
	run Setup.
Always	A password prompt appears every time when the com-
	puter is powered on or when end users try to run Setup.

Boot To OS/2

This allows you to run the OS/2® operating system with DRAM larger than 64MB. When you choose No, you cannot run the OS/2® operating system with DRAM larger than 64MB. But it is possible if you choose Yes.

Internal Cache

Cache memory is additional memory that is much faster than conventional DRAM (system memory). When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. The setting controls the internal cache (also known as L1 or level 1 cache). Setting to Enabled will speed up the system performance.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Setting options: Enabled, Disabled.

C000, 32k Shadow

This item specifies how the contents of the adapter ROM named in the item are handled. Settings are described below:

Option	Description
Disabled	The specified ROM is not copied to RAM.
Enabled	The contents of specified ROM are copied to RAM
	for faster system performance.
Cached	The contents of specified ROM are not only copied
	to RAM, the contents of the ROM area can be writ-
	ten to and read from cache memory.
