AMI BIOS SETUP
~ 32 ~
Configure SDRAM Timing by SPD:
This option provides DIMM plug-and-play support by Serial
Presence Detect (SPD) mechanism via the System Management Bus (SMBus) interface. You
can disable this option to manage the following SDRAM timing options by yourself. In addition,
SDRAM operating timings may follow serial presence from EEPROM content by setting this
option to "Enabled", and all of SDRAM timing options will be not available and hidden.
Memory Hole:
This option allows the end user to specify the location of a memory hole for
memory space requirement from ISA-bus cards.
AGP Read Synchronization:
Enabled is best for performance.
AGP Fast Write:
Allows data to be sent directly from the corelogic (i.e. chipset) to the AGP
master (graphics chip) instead of keeping a copy in system memory and making the AGP master
fetch it. Enabled is best for performance, and probably only works with 4x cards anyway.
AGP Aperture Size
: This option specifies the amount of system memory that can be used by the
Accelerated Graphics Port (AGP).
AGP Master 1 W / S Write:
Implements a single delay when writing from the AGP Bus. Normally,
two wait states are used, allowing for greater stability.
AGP Master 1 W / S Read:
Implements a single delay when reading from the AGP Bus.
Normally, two wait states are used, allowing for greater stability.
PCI Delay Transaction:
Choose the "Enabled" option to obtain higher PCI bus performance for
slower ISA bus application
.
USB Controller
: This option will enable on-chip USB controller to support USB (Universal Serial
Bus) peripheral devices if user chooses the "Enabled" setting.
USB Device Legacy Support:
This field support Universal Serial Bus (USB) devices. If detected,
USB controller legacy mode will be enabled. If not detected, USB controller legacy mode will be
disabled.
Port 64/60 Emulation:
Setting this option to allow a USB Keyboard to act like a legally keyboard.
