Have you compiled your kernel for SMP mode? I believe the Low memory offset mode is only for AMP mode (vxworks can use this, probably other OSes). I don't know if the kernel has support for any multiprocessing mode other than SMP.

Have you compiled your kernel for SMP mode?  I believe the Low = memory
offset mode is only for AMP mode (vxworks can use this, probably = other
OSes).  I don't know if the kernel has support for any = multiprocessing
mode other than SMP.

Hope that helps,
