When i execute this instruction in the bios code:
"movd %eax,%xmm0" produces an exception.
when i execute "movd %eax,%mm0" works.

Wise any, how to activate the SSE 128bit registers for
the VIA C7?

In another computers with another BIOS, the code works
fine, and not makes any exception, but in the VIA C7

Can one help me?
