Added files:
sys/boot/i386/libi386 smbios.c
Log:
Scan static SMBIOS structures and export the following environment
variables to loader:
hint.smbios.0.enabled "YES" when SMBIOS is detected
hint.smbios.0.bios.vendor BIOS vendor
hint.smbios.0.bios.version BIOS version
hint.smbios.0.bios.reldate BIOS release date
hint.smbios.0.system.maker System manufacturer
hint.smbios.0.system.product System product name
hint.smbios.0.system.version System version number
hint.smbios.0.planar.maker Base board manufacturer
hint.smbios.0.planar.product Base board product name
hint.smbios.0.planar.version Base board version number
hint.smbios.0.chassis.maker Enclosure manufacturer
hint.smbios.0.chassis.version Enclosure version
These strings can be used to detect hardware quirks and to set appropriate
flags. For example, Compaq R3000 series and some HP laptops require
hint.atkbd.0.flags="0x9"
to boot. See amd64/67745 for more detail.
Note: Please do not abuse this feature to resolve general problem when it
can be fixed programmatically. This must be used as a last resort.
