7. BIOS CONFIGURATION OVERVIEW
7.1. Default settings
If BIOS settings are misconfigured and the MLC therefor behaves unexpected, restore the BIOS de-
fault settings.
1. Boot MLC and press <DEL> key on POST/boot logo screen short after keyboard is initialized
(indicated by flashing keyboard LEDs), then
2. press <F3> key
3. press <ENTER> key
4. press <F4> key
5. press <ENTER> key again
MLC reboots with BIOS default settings.
Note: This procedure works even if the display output stays dark and the BIOS itself is not corrupted.
7.2. Enable ACPI S3 state
The BIOS default values set the deepest CPU sleep mode to S1 only. This prevents an OS from set-
ting the MLC into S3 (Suspend To RAM) which results in higher power consumption.
To save energy, enable S3 via BIOS setting.
1. Boot MLC and press <DEL> key on POST/boot logo screen short after keyboard is initialized
(indicated by flashing keyboard LEDs), then
2. move with cursor keys to Advanced
3. move with cursor keys to and press <ENTER> key
4. option S1 only(CPU Stop Clock) is set, press <ENTER> key
5. move with cursor keys to option S3 only(Suspend To RAM)
6. press <ENTER> key to select and confirm
7. press <F4> key
8. press <ENTER> key to save settings and reboot MLC
7.3. Enable PXE/network boot
Sometimes it might be necessary to boot the MLC from a network. To enable the Pre-Boot-Execution
(PXE) ROM for the integrated Ethernet ports and set the proper boot sequence, proceed with the fol-
lowing steps:
1. Boot MLC and press <DEL> key on POST/boot logo screen short after keyboard is initialized
(indicated by flashing keyboard LEDs), then
2. move with cursor keys to Boot
3. move with cursor keys to Launch PXE OpROM and press <ENTER> key
