Allows you to set: (continued)
• Hyper-threading (enable/disable)
• Set Up Browse Mode (enable/disable). 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.
Restarts the computer and executes the POST memory test.
Allows you to set the computer to turn on automatically at a time you
specify.
Allows you to set resources for or disable onboard system devices
(diskette controller, serial port, or parallel port).
• Lists currently installed PCI devices and their IRQ settings.
• Allows you to reconfigure IRQ settings for these devices or to
disable them entirely. These settings have no effect under an
APIC-based operating system.
Displayed only if there are multiple PCI video adapters in the
system. Allows you to specify which VGA controller will be the
"boot" or primary VGA controller.
On some models, allows you to enable or disable:
• PCI SERR# Generation.
• PCI VGA palette snooping, which sets the VGA palette
snooping bit in PCI configuration space; only needed when
more than one graphics controller is installed.
