I installed arch linux in a virtuabox and created a chroot for it with= mkarchroot. Transferred it to my pogo plug into /i386/ 2. I comiled qemu-i386 static and put it into /i386/usr/bin/ ./configure --static --disable-blobs --disable-system --target-list=3Di38= 6-linux-user make 3. I also compiled linux kernel 2.6.38 with CONFIG_BINFMT_MISC=3Dy and in= stalled it. uname -a Linux Plugbox 2.6.38 #4 PREEMPT Fri Mar 18 22:19:10 CDT 2011 armv5tel Fer= oceon 88FR131 rev 1 (v5l) Marvell SheevaPlug Reference Board GNU/Linux 4.

Also copied ld-linux.so.3 (actually ld-2.13.so because ld- linux.so.3 is a link to that file) from /lib/ to /i386/lib/ 6.Now i chroot into /i386 and I get this: [root@Plugbox i386]# chroot .
