vdmexec.c [NTOS/PERF]: Enable VME support. VME stands for Virtual 8086 Mode Extensions, and it's an Intel optimization that makes changes to the IF bit in EFLAGS (CLI, STI, INT, IRETD, PUSHF, POPF) completely transprent: instead of changing the real (protected) bit, which requires the OS to trap and emulate the behavior, the CPU sets a "Fake" IF bit instead. When you're dong in V8086 mode, you simply update your real flag with whatever the fake flag says. 2010-01-27 05:34:38 +00:00
vdmmain.c - Don't put VdmpInitialize in .INIT either as it is not called during kernel initialization, but from videoport driver during its initialization. CORE-10097 2015-09-03 16:52:28 +00:00
