env-common.mac@ 49671

Last change on this file since 49671 was 49671, checked in by vboxsync, 11 years ago
IEM: Fixed several instances of iEffSeg being accessed before the decoding was over, causing iPXE to guru on us. Implemented DAS and DAA to verify the previous fix.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
