Chapter 4 BIOS Setup
ReadyBoard 800 Reference Manual 65
♦ Serial Console – [Hot Cable] or [Enabled]
* If the [Hot Cable] option is selected, it only allows serial console (console redirection)
operation when a Hot Cable is actually connected to Serial 1 or Serial 2 (COM 1 or 2).
Use the modified serial cable described in Chapter 3, under Hot (Serial) Cable.
* If the [Enabled] option is selected, it instructs the BIOS to operate in the serial console
(console redirection) mode at all times with the serial port selected in the Serial Console >
Port field listed below. Use a standard null-modem serial cable.
* If a Hot Cable is connected to the other port (port not selected) the Hot Cable will
override the settings in this field [Enabled] and the Serial Console > Port field.
♦ Port – [3F8h], [2F8h], [3E8h], or [2E8h]
This field selects the COM (Serial) port address used for serial console (console redirection)
when [Enabled] has been selected in Serial Console. Use a standard null-modem serial cable.
∗ If you connect a Hot Cable to another port (port not selected) this action overrides this
field setting and activates the connected port. Connecting a Hot Cable to one of the serial
ports only allows console redirection when a Hot Cable is actually connected to Serial 1
or 2. Use the modified serial cable described in Chapter 3, under Hot (Serial) Cable.
♦ Auto Poweron – [Disabled] or [Enabled]
This field selects the power-on state of the ReadyBoard 800 when power is applied initially to
the board, or after a power loss to the power supply, and determines when the ReadyBoard
800 powers up. If you change this BIOS setting, it takes one complete power on/ off cycle
before it takes effect.
* If this field is set to [Enabled], the ReadyBoard 800 goes immediately to a complete
power on state, enabling the boot process, as soon as power is applied to the board or
power supply. This occurs without the use of the external Power-On switch connected to
the Utility connector (J12), if the external battery is connected. Normally, this would only
happen during the initial power on process or during the ReadyBoard 800's recovery after
a power loss to the power supply.
NOTE If the external battery is disconnected at BT1, then setting this
feature to [Enabled] will not function as specified. You must use
the external Power-On switch connected to the Utility connector
(J12) to completely power on the board, if the external battery is
disconnected or inoperable.
* If this field is set to [Disabled], the ReadyBoard 800 goes to standby in all situations until
you enable it with the external Power-On switch connected to the Utility connector (J12).
♦ SMM Support – [Disabled] or [Enabled]
This field was created to disable all SMI (System Management Interrupt) activity. This
feature should only be used in special cases and then only when SMI activity would degrade
Realtime response.
* If this field is set to [Enabled], the default setting, SMI functions are enabled allowing the
Watchdog Timer, ACPI functions and the USB boot features to operate normally.
* If this field is set to [Disabled], the Watchdog Timer, ACPI functions, and USB boot
features will not operate.
CAUTION Do not Disable the SMM Support feature, unless you are thoroughly
convinced you need it. This feature is only used for special cases
when all SMI activity needs to be halted, which will disable many
features of your system, including the Watchdog Timer, ACPI
functions, and USB boot features.
