[Qemu-devel] setting OEM ID in BIOS from qemu?

[Michael Tokarev]

Hello.

What's the possible way(s) to set OEM identification
string in BIOS too, so that it provides ACPI tables
with the given identification?

It is needed to support running OEM version of windows
vista and windows 7 (for example) from /dev/sda without
voiding its activation - this needs a real SLIC table
plus the corresponding string other tables (FACP, FACS,
-- I don't know for sure which other table windows
checks, exactly).

First is already available on the host system in
/sys/firmware/acpi/tables/SLIC, and it's possible
to use this table directly with -acpitable file=...
after my patch for hw/acpi.c which I submitted today
for qemu.

The second component is missing currently, hence
this my question.

Thanks!

A fwcfg entry probably needs to be added to pass the information.
Then SeaBIOS could be extended to fill the tables it generates with
the given fields.
