General Information 17
Palette Snooping
The default setting is “Disabled“. It is necessary to
enable palette snooping if your system has a video
multimedia adapter installed and incorrect colors are
displayed on screen, and also your system has a PCI
video adapter installed that supports palette
snooping.
Video Interrupt
This parameter allows you to select “Disabled” for the
video interrupt if your video adapter does not require
an interrupt and your system is having problems
assigning interrupts to other adapters that need them.
The default is set to “Enabled“.
IDE Drive Setup
The Device and I/O Ports menu includes four IDE
drive items that allow you to configure the hard disk
drives and the CD/CD-R/W-ROM drive. Selecting any
one of these items displays a submenu with details
on a particular IDE drive.
The IDE drive items are identified as follows:
IDE Hard Disk Drive 0
IDE Hard Disk Drive 0 is attached to IDE connector 1
on the system board. This is the hard disk that
comes pre-installed with your computer.
Size:
It is not configurable. The BIOS will auto-detect the
size from the hard disk drive.
IDE Performance:
The “High Performance“ mode allows IDE devices
attached to the system board IDE controller to
utilize any performance enhancement features the
device may support. If an IDE device attached to
the system board IDE controller does not function
properly or causes other IDE devices attached to
the same controller not to function properly, set
this field to the “Compatible“ mode. This will allow
other IDE hard disk drives or IDE devices which do
not follow the ATA IDE specification to function
properly. The default is set to “High
Performance“.
