Power-On Options
(continued)
Allows you to set:
• I/O APIC Mode (enable/disable).
Enabling this feature will allow Microsoft
Windows Operating Systems to run
optimally. This feature must be disabled
for certain non-Microsoft Operating
Systems to work properly.
• Hyper-threading (enable/disable).
• Set Up Browse Mode (enable/disable)
(some models). Enabling this feature
permits Computer Setup to be viewed, but
not changed, without entering the setup
password.
• Limit CPUID Maximum Value to 3. Restricts
the number of CPUID functions reported
by the microprocessor. Enable this feature
if booting to WinNT.
• ACPI/USB Buffers @ Top of Memory
(enable/disable). Enabling this feature
places USB memory buffers at the top
of memory. The advantage is that
some amount of memory below 1 MB is
freed up for use by option ROMs. The
disadvantage is that a popular memory
manager, HIMEM.SYS, does not work
properly when USB buffers are at top of
memory AND the system has 64 MB or
less of RAM.
Execute Memory Test
(some models)
Restarts the computer and executes the POST
memory test.
BIOS Power-On Allows you to set the computer to turn on
automatically at a time you specify.
