From 1fdd39d371ecd0c660dce8926add29846c95cd37 Mon Sep 17 00:00:00 2001 From: davidhuang Date: Fri, 20 Nov 2009 04:02:03 +0000 Subject: 1. PI SMBIOS Checkin. Major change include: 1) Produce PI SMBIOS protocol in MdeModulePkg 2) Update all consumers (in CorePkgs and native platform pkgs) to consume SMBIOS protocol instead of DataHub 3) Pass ECC tool; Verify Nt32, Duet, Unix platform git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9457 6f19259b-4bc3-4df7-8a09-765794883524 --- .../MiscBiosVendorFunction.c | 210 +++++++++++++++++++++ 1 file changed, 210 insertions(+) create mode 100644 Nt32Pkg/MiscSubClassPlatformDxe/MiscBiosVendorFunction.c (limited to 'Nt32Pkg/MiscSubClassPlatformDxe/MiscBiosVendorFunction.c') diff --git a/Nt32Pkg/MiscSubClassPlatformDxe/MiscBiosVendorFunction.c b/Nt32Pkg/MiscSubClassPlatformDxe/MiscBiosVendorFunction.c new file mode 100644 index 0000000000..513a10164b --- /dev/null +++ b/Nt32Pkg/MiscSubClassPlatformDxe/MiscBiosVendorFunction.c @@ -0,0 +1,210 @@ +/*++ + +Copyright (c) 2009, Intel Corporation.
