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.
