for binary mode, this commit message is most helpful

    qemu: Add support for SMBIOS command line otions (Alex Williamson)
    
    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.
