Thanks for answer Rudolf, the CPU can SSE and SSE2, when runs with normal BIOS the instruction "movd %eax,%xmm0" works in, but if the linuxbios need working with sse and sse2 with a microKernel for example, this instruction produces a exception.
My contents of the /proc/cpuinfo says:
processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 10 model name : VIA Esther processor 1000MHz stepping : 9 cpu MHz : 65535.000 cache size : 128 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce sep mtrr pge cmov pat clflush acpi mmx fxsr sse sse2 tm up pni est tm2 rng rng_en ace ace_en ace2 ace2_en phe phe_en pmm pmm_en bogomips : 1598.31 clflush size : 64
The problem is that the BIOS must enable XMM registers or the flags from CR4? if not only works MMX registers with SSE and SSE2 integer addons.
And i not known what must this CPU for enable it, or all CPU's.
Lots of thanks if one can help me!.

Hi,
You need to have CPU of model 9.
What cat /proc/cpuinfo says?
(or apt-get install cpuid; cpuid )
Thanks, Rudolf
