* OVMF VTF0 Reset Vector: Set 'accessed' bit in GDT descriptorsjljusten2010-01-047-5/+5
| | | | | | | | In some environments, the accessed bit should be set to allow the global descriptor table (GDT) to reside in unmodifiable flash memory. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9675 6f19259b-4bc3-4df7-8a09-765794883524
