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
.
Hyper Threading Function
This field is used to enable or disable the Hyper Threading function. Setting to
Enabled will increase the system performance. Settings:
Enabled
,
Disabled
.
MPS Revision
This field allows you to select which MPS (Multi-Processor Specification)
version to be used for the operating system. You need to select the MPS
version supported by your operating system. Settings:
1.4
and
1.1
.
APIC ACPI SCI IRQ
This field is used to enable or disable the APIC (Advanced Programmable Inter-
rupt Controller). Due to compliance to PC2001 design guide, the system is able
to run in APIC mode. Enabling APIC mode will expand available IRQs resources
for the system. Settings:
Enabled
and
Disabled
.
CPU L1 & L2 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
WriteBack
will speed up the system performance.
Enabling the functionality of Hyper-Threading Technology
for your computer system requires ALL of the following
platform Components:
*CPU: An Intel
®
Pentium
®
4 Processor with HT Technology;
*Chipset: An Intel
®
Chipset that supports HT Technology;
*BIOS: A BIOS that supports HT Technology and has it
enabled; and
*OS: An operating system that supports HT Technology.
