Security Option
This specifies the type of BIOS password protection that is implemented.
Setting options are described below.
Option
Setup
Always
Boot OS/2 for DRAM > 64MB
This allows you to run the OS/2
DRAM. When you choose No, you cannot run the OS/2
with more than 64MB DRAM. 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 options: Disabled, WriteBack, Write Thru. WriteBack
& WriteThru refer to the cache's write policy, which determines how it handles
writes to memory locations that are currently being held in cache. The WriteBack
cachelpolicy will produce the best performance.
HT CPU Function
This field is used to enable or disable the Intel Hyper Threading CPU function.
Setting to Enabled will increase the system performance. Settings: Enabled,
Disabled. Please disable this item if your operating system doesn't support
HT Function, or the irreliability and unstability may occur.
Note: Enabling the functionality of Hyper-Threading Technology for
your computer system requires ALL of the following platform
Components:
*CPU: An Intel
*Chipset: A chipset that supports HT Technology;
*BIOS: A BIOS that supports HT Technology and has it enabled; and
*OS: Only Microsoft
