//
// 5 7/08/09 8:02p Markw
// Update headers.

// 4 5/21/09 9:52a Markw
// Added comments for the FarCall86 and FarCall86Ex may be used to do INT
// XX calls.
//
// 3 3/03/08 6:35p Markw
// Added 32-bit register for smm thunk.
//
// 2 10/29/07 11:00a Markw
// Update register name. It was the same as CSM, which caused a symbol
// redefintion when CSM headers are used with this header.
