[BusyBox] RE: [Bochs-developers] bug: SSE2 instruction still not implemented (x86-64 emulation) - executing busybox df

[Stanislav Shwartsman]

CVTSI2SD_VsdEd - Convert one signed doubleword integer from r/m32 to one
double-precision floating-point value in xmm.
Opcode bytes F2 0F 2A /r

Event type: PANIC
Device: [CPU0 ]
Message: CVTSI2SD_VsdEd: SSE2 instruction still not implemented

What is busybox ?
If it using floating point it may be compiled with SSE intruction
instead of FPU one because of SSE instructions are much faster.

OK, I booted from a Grub boot disk and managed to install grub on an
image I 
just created with bximage, and partitioned inside bochs itself using
your 
debian image as hda and my image as hdb.

It´s working now. Thanks, Robert!

But when I tried to execute the command ´df´ as implemented by busybox,
I got 
the following message:

----
00000000000i[     ] using log file bochsout.txt
========================================================================
Event type: PANIC
Device: [CPU0 ]
Message: CVTSI2SD_VsdEd: SSE2 instruction still not implemented

A PANIC has occurred.  Do you want to:
  cont       - continue execution
  alwayscont - continue execution, and don't ask again.
               This affects only PANIC events from device [CPU0 ]
  die        - stop execution now
  abort      - dump core
Choose one of the actions above: [die]
========================================================================
Bochs is exiting with the following message:
[CPU0 ] CVTSI2SD_VsdEd: SSE2 instruction still not implemented
========================================================================

Anybody has any idea why? What is the SSE2 instruction and why is
busybox 
using SSE2 for a simple ´df´? This busybox for AMD64 was compiled with 
glibc-2.3.1 and statically linked.

Thanks for any help,
