You just probably didn't match the CFLAGS and/or MMX/SSE USE flags to the "underpowered system" but compiled your binaries for the faster architecture. I guess you are right. for i686 system I have CFLAGS="-march=i686 -O2 -pipe" CHOST="i686-pc-linux-gnu" If I recall correctly now , //proc/cpuinfo shows this as a Pentium4 with flags showing sse sse2 . Even the gentoo i686 livecd does not boot on the mythtv system. Just after uncompressing the kernel, system reboots. I think I will have to use a rescue CD of some sort. thanks sathish -hwh -- [EMAIL PROTECTED] mailing list -- [EMAIL PROTECTED] mailing list

Nothing. It works just fine (I did this enough times before).
