Force a real, platform-anchored OEM BIOS identity into SMBIOS type0 (patch 0024 + spoof_bios_version/spoof_bios_date getters) so the guest does not read an empty or firmware-default BIOS vendor via WMI/dmidecode. Vendor coheres with the board; version uses the vendor real format. Inert without a seed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

qemu-spoof: SMBIOS type0 BIOS vendor / version / date
|
|
|
|
Stock QEMU leaves type0 vendor/version/date unset, so the guest reads an empty or
|
|
firmware-default ("SeaBIOS") BIOS identity via WMI Win32_BIOS / dmidecode -- a tell.

|
Force a real, platform-anchored OEM BIOS identity (vendor coheres with the board;
|
|
version uses the vendor's real format) through smbios_set_defaults, so an explicit
|
|
-smbios type=0 still wins and an un-seeded VM stays stock. (spoof.h include added by
|
|
0015-smbios-vm-bit.)
