Cc: qemu-devel@nongnu.org Subject: [Qemu-devel] [PATCH][SEABIOS] Make SMBIOS table pass MS SVVP test X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Microsoft SVVP (Server Virtualization Validation Program) expects arbitrary SMBIOS field to have certain values otherwise it fails. We all want to make Microsoft happy don't we? So lets put values MS expects in there. Values modified by the patch: Type 0: Bit 2 of byte 2 must be 1 Type 1: Manufacturer/product string should not be empty Type 3: Manufacturer string should not be empty Type 4: Processor manufacturer should no be empty Max/current CPU speed shouldn't be unknown Type 16: Memory should have error correction.
