2.4.12 BIOS
The SKY-8260S 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-8260S 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 Display Port or serial
console. Please refer to
Section 3.2
the console connection process.
The BIOS Setup Menu is described in detail in
. BIOS Error Codes used
Note!
Please note that the SKY-8260S 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.
2.4.12.1 Password Protection
The BIOS supports and administrator password to restrict access to the BIOS setup
menu to qualified and trusted personal, only.
2.4.12.2 BIOS Defaults
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.
2.4.12.3 PCIe Tree
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:
2.4.13 Advanced Platform Management
Advanced Platform Management is supported via an integrated BMC running IPMI2.0
compliant system management firmware. Several enhancements have been made to
standard white box server management code to enhance reliability and serviceability of
the system including but not limited to:
