I know nothing about fxrstor, but the docs do also say: Bit 6 and bits 16 through 32 of the MXCSR register are defined as reserved and should be set to 0. Attempting to write a 1 in any of these bits from the saved state image will result in a general protection exception (#GP) being generated. Worth checking? N |
