2.4.3 BIOS

The SKY-8100's BIOS is based on Advantech's APTIO BIOS and compliant to the UEFI,

SMBIOS and ACPI specifications.

The BIOS performs probing, initialization and configuration of the SKY-8100 and

initializes the OS boot process at the end of POST (Power On Self Test).

Regular BIOS output as well as the setup menu are displayed via VGA or serial

console. Please refer to section 0 reg. the console connection process.

The BIOS Setup Menu is described in detail in

during POST are described in appendix 0.

Please note that the SKY-8100 does not have any onboard POST Code LEDs onboard.

POST Codes are logged via the BMC's POST Code Sensor, though.

All BIOS configuration parameters bare stored in NVRAM, a dedicated section of the

BIOS flash chip. Parameters are no longer stored in legacy CMOS RAM by the platform

BIOS. I.e. BIOS configuration parameters will not be lost due to an empty RTC battery.

The BIOS supports and administrator password to restrict access to the BIOS setup

menu to qualified and trusted personal, only.

The BIOS comes with a set of configuration parameters when shipped by Advantech

referred to as "Optimized Defaults" or "factory defaults". The user can change

BIOS settings via the setup menu either temporarily or permanently by saving the

changes as "User defaults".

The BIOS loads the User defaults automatically if these have been defined via the

setup. If no User defaults have been defined; the BIOS will load the factory defaults.

The BIOS also performs an enumeration of all PCIe resources, builds a bus/device map

and assigns resources to the PCIe devices. Most OSes perform a reallocation of

resources during start up. However, the PCIe bus/device map will not be changed by

the OS. The table below gives an overview of the PCIe devices and their corresponding

system function:
