I know qemu produces the acpi and smbios tables. I wasn't aware it will currently pass in the mptable to seabios. (Nor the PIR table.) I'm okay with removing support from seabios. As a first step we can change the Kconfig defaults to not produce the tables. -Kevin _______________________________________________ SeaBIOS mailing list -- seabios@seabios.org To unsubscribe send an email to seabios-le...@seabios.org
