Power-On Options
(continued)
Allows you to set: (continued)
POST Delay (in seconds) (enable/disable). Enabling this
feature will add a user-specified delay to the POST process.
This delay is sometimes needed for hard disks on some PCI
cards that spin up very slowly; so slowly that they are not ready
to boot by the time POST is finished. The POST delay also gives
you more time to select F10 to enter Computer (F10) Setup.
I/O APIC Mode (enable/disable). Enabling this feature will
allow Microsoft Windows Operating system to run optimally.
This feature must be disabled for certain non-Microsoft
Operating Systems to work properly.
ACPI/USB Buffers @ Top of Memory (enable/disable).
Enabling this feature places USB memory buffers at the top of
memory. The advantage of remapping is that it allows space in
the DOS Compatibility Hole range, below 1MB, to be made
available for additional PCI plug-in cards that need option
ROM space. 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 KB or less
of RAM.
Hot-Pluggable MultiBay Floppy* (enable/disable). Enabling
this feature allows you to hot-plug a MultiBay floppy into a
system running Windows 2000 or XP.
BIOS Wakeup* Allows you to set the computer to turn on automatically at a
time you specify.
Onboard Devices Allows you to set resources for or disable onboard system
devices (serial port, parallel port, or diskette controller).
PCI Devices 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.
Bus Options* Allows you to enable or disable:
PCI bus mastering, which allows a PCI device to take control of
the PCI bus.
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.
PCI SERR# generation.
ECC support allows hardware-based error correction for
ECC-capable memories.
*Available on select models.
**These options should be used by advanced users only.
