Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.
Binary SMBIOS entries can be generated as follows:
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin
These can then be passed to the BIOS using this switch:
-smbios file=smbios_type_1.bin
Command line generation supports the following syntax:
-smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
-smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
[,uuid=$(uuidgen)][,sku=str][,family=str]
For instance, to add a serial number to the type 1 table:
-smbios type=1,serial=0123456789
Interface is extensible to support more fields/tables as needed.
