Hello all!

I heve a problem with SSE2 instruction. Use of any instruction e.g.

PXOR XMM0, XMM0 results in exception no 6.

According to Intel manual this happens when bit 2 in CRO is set but in my
case CR0 has value of 0x00000011 so in theory it's not possible.

I used EMMS instruction before PXOR XMM0, XMM0 - unsuccessfully, instruction
CPUID shows that my processor has SSE2 extension

(I have P4 processor). What am I doing wrong?

Best regards
