On-Chip USB1.1 Controller
This feature allows users to enable/disable the USB1.1 controller.
USB Keyboard Support
This feature allows users to determine whether the USB keyboard is supported by the
BIOS or the operating system. If users
’
operating system supports the USB keyboard,
such as Windows XP, they shall
disable
this feature. If not, this feature shall be
enabled
. But this only provides the basic functions for the USB keyboard.
USB Mouse Support
This feature allows users to determine whether the USB mouse is supported by the
BIOS or the operating system. If users
’
operating system supports the USB mouse,
such as Windows XP, they shall
disable
this feature. If not, this feature shall be
enabled
. But this only provides the basic functions for the USB mouse.
On-Chip USB2.0 Controller
This feature allows users to enable or disable the motherboard
’
s onboard USB 2.0
controller. If
enabled
, users are allowed to communicate with the USB 2.0 devices via
the USB 2.0 controller.
Enabled
is recommended unless you decide not to use any of
the USB 2.0 devices.
Init Display First
This BIOS feature allows users to select whether to boot the system using the AGP
graphics card or the PCI graphics card. This is particularly important if you have AGP
and PCI graphics cards but only one monitor.
If you are only using a single graphics card, then the BIOS will detect it as such and
boot it up, irrespective of what you set the feature to. However, there may be a slight
reduction in the time taken to detect and initialize the card if you select the proper
setting for this BIOS feature. For example, if you only use an AGP graphics card, then
setting Init Display First to
AGP
may speed up your system's booting-up process.
Therefore, if you are only using a single graphics card, it is recommended that you set
the Init Display First feature to the proper setting for your system (
AGP
for a single
AGP card and
PCI
for a single PCI card
).
But if you are using multiple graphics cards, it is up to you which card you want to
use as your primary display card. It is recommended that you select the fastest
graphics card as the primary display card.
IDE HDD Block Mode
This feature enables users to speed up the hard disk access by transferring the data in
the block mode.
Enabled
is recommended.
