#UD If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
If CPUID.01H:EDX.SSE[bit 25] = 0.
If the LOCK prefix is used.
#AC(0) If alignment checking is enabled and an unaligned memory
reference is made while the current privilege level is 3.
Real-Address Mode Exceptions
GP(0) If any part of the operand lies outside the effective address
space from 0 to FFFFH.
#NM If CR0.TS[bit 3] = 1.
#UD If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
If CPUID.01H:EDX.SSE[bit 25] = 0.
If the LOCK prefix is used.
Virtual-8086 Mode Exceptions
