[SeaBIOS] [PATCH v2 0/6] Fix reported version and date for Windows guests

Posted by Sam Eiderman 21 weeks ago
v2:

Offer a better commit for:

    "bios_version: Remove misinterpreted version string"

Which doesn't change the debug string but rather creates the original
one dynamically.
Thanks, Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>.

v1:

Windows kernel extracts various BIOS information at boot-time.
The method it uses to extract SystemBiosDate & SystemBiosVersion which
are then stored in:
    * "HKLM\HARDWARE\DESCRIPTION\System" "SystemBiosDate"
    * "HKLM\HARDWARE\DESCRIPTION\System" "SystemBiosVersion"
is very hueristic and depends on data contained in the BIOS's data
section.
The implementation resides in:
    * nt!CmpGetBiosVersion()
    * nt!CmpGetBiosDate()
respectively.
For reference implementation, see ReactOS:
https://doxygen.reactos.org/d5/dd2/i386_2cmhardwr_8c.html

This patch series aims to make SeaBIOS's data section interact better
with the Windows OS and report correct date & version values.

Liran Alon (4):
  bios_date: Make all dates in BIOS consistent
  bios_date: Make bios date appear once in the ROM
  bios_date: Change BiosDate to SMBIOS bios date
  bios_version: Remove misinterpreted version string

Sam Eiderman (2):
  bios_date: Add bios date checks in checkrom.py
  bios_version: Add bios version checks in checkrom.py
