Power-On Options

Allows you to set: (continued)

(continued)

(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.
