Chapter 3 AMI BIOS 3
3.1 Introduction AMI BIOS has been integrated into many motherboards for over a decade. In the past, people often referred to the AMI BIOS setup menu as BIOS, BIOS setup or CMOS setup. With the AMI BIOS Setup program, you can modify BIOS settings and control the special features of your computer. The Setup program uses a number of menus for making changes and turning the special features on or off. This chapter describes the basic navigation of the ASMB-820I setup screens.
3.2.1 Main Menu Press to enter AMI BIOS CMOS Setup Utility, the Main Menu will appear on the screen. Use arrow keys to select among the items and press to accept or enter the sub-menu. Chapter 3 3.2 BIOS Setup AMI BIOS The Main BIOS setup screen has two main frames. The left frame displays all the options that can be configured. Grayed-out options cannot be configured; options in blue can be. The right frame displays the key legend.
3.2.2.1 PCI Subsystem Settings PCI ROM Priority Default setting is EFI Compatible mode. In case PCI legacy Option ROM required, you can change the mode from EFI to Legacy.

Limit CPUID Maximum Setting this item to [Enable] allows legacy operating systems to boot even without support for CPUs with extended CPUID functions. Execute Disable Bit This item specifies the Execute Disable Bit Feature. The settings are Enabled and Disabled. The Optimal and Fail-Safe default setting is Enabled. If Disabled is selected, the BIOS forces the XD feature flag to always return to 0.
Chapter 3 AMI BIOS User can set “EIST”, “P-STATE”, “C3”, “C6”, “C7”, “Package C State limit” under “Custom” Mode. 3.2.2.6 Runtime Error Logging User can enable or disable Runtime Error Logging Support.
3.2.2.7 SATA Configuration SATA Mode Configured as IDE/RAID/AHCI or disabled. IDE Mode Serial-ATA Controller 0 This item appears only when SATA Mode item set to [IDE Mode]. Set to [Enhanced] to support two SATA 6.0 Gb/s and four SATA 3.0 Gb/s devices. Set to [Compatible] when using Windows 98/NT/2000/MS-DOS. Up to four SATA devices are supported by controller 0 and two SATA devices are supported by controller 1 when under these operating systems.
Serial-ATA Controller 1 Chapter 3 AMI BIOS Set to [AHCI Mode] to have the SATA hard disk drives use the AHCI (Advanced Host Controller Interface). The AHCI allows the onboard storage driver to enable advanced Serial ATA features that increases storage performance on random workloads by allowing the drive to internally optimize the order of commands. RAID Mode Set to [RAID Mode] to create a RAID configuration from the SATA hard disk drives.
3.2.2.8 USB Configuration Legacy USB Support This is for supporting USB devices under a legacy OS such as DOS. When choosing "AUTO", the system will automatically detect if any USB device is plugged into the computer and enable USB legacy mode when a USB device is plugged in and disable USB legacy mode when no USB devices are plugged in. EHCI Hand-off Enables or disables supporting an OS without EHCI hand-off feature. USB Transfer Time-out Selects the USB transfer time-out value.

Parity A parity bit can be sent with the data bits to detect some transmission errors. Even: parity bit is 0 if the num of 1's in the data bits is even. Odd: parity bit is 0 if num of 1's the data bits is odd. Mark: parity bit is always 1. Space: Parity bit is always 0. Mark and Space Parity do not allow for error detection.
Console Redirection Setting Out-of-Band Mgmt Port Used to select the COM port a user would like to set for having console redirection. Terminal Type Set as "VT100", "VT100+", "VT-UTF8", or "ANSI". "VT-UTF8" is the default setting. Bits Per Second To select serial port transmission. Speed must be matched on the other side. It can be set as "9600", "19200", "57600", or "115200". "115200" is the default setting. Flow Control Flow control can prevent data loss from buffer overflow.
