Using BIOS Setup 5-6
Advanced Menu
The Advanced menu contains the various system settings.
Legacy USB Support enables the system's support for Legacy USB
device (e.g., mouse, flash disk, except keyboard) in DOS mode. The
options are Enabled and Disabled. Default is Enabled.
Frame Buffer Size sets the shared memory size of the video controller.
The options are 64MB, 128MB, and 256MB. Default setting is 64MB.
NOTE:
 This item is for Legacy VGA and SVGA mode only. When under Windows mode,
the frame buffer size is allocated directly by the VGA driver based on the size of
your system memory.
 Increasing the frame buffer size may improve the video subsystem’s performance,
however it may decrease your system memory.
SATA0 Mode set to AHCI if your system supports AHCI. AHCI allows
you to take advantage of Advanced Host Controller Interface features
such as Native Command Queuing. The options are IDE and AHCI.
Default is AHCI.
