10 executes the bios components such as acpi and smbios tables directly through
11 acpica bios interpreter (a freely available C based library written by Intel,
14 with grub so actual routines that executes bios components can be written in
16 There are several advantages to directly testing the bios in a real physical
17 machine or in a VM as opposed to indirectly discovering bios issues through the
18 operating system (the OS). Operating systems tend to bypass bios problems and
