Hi! Sorry for the obvious typos and inefficiencies, but it was kinda late ;-) I enhanced and optimized the procedure a little - without the "dirty" boot. You can now do most of the procedure in the comfort of your host OS.
(1) For that I took a kernel from http://people.debian.org/~aurel32/qemu/mipsel/ (2) I made a raw disk (ben.img) of 512 megs, partitioned it and made a Linux partition; under an ARM(!) emulated Linux (it's much easier that way than a looped device). Exit the emulation and enter your host system again. (3) Mount it with "mount -o loop,offset=31232 -t ext2 ben.img /mnt" (4) wgetted the openwrt*-rootfs.tar.gz (5) cd /mnt; tar -xzvf <path>openwrt*-rootfs.tar.gz (6) cd /mnt/dev; mknod console c 5 1 (7) Populated /dev a bit more (disk, null and tty - see below); chmod 777 * (8) cd /mnt/etc; mv inittab inittab.old; cd init.d; mv rcS rcS.old (9) vi rcS; lines "#!/bin/sh<cr>mount -t proc proc /proc" added (10) umount /mnt (11) Booted with: qemu-system-mipsel -m 32 -kernel vmlinux-qemu -hda ben.img -append "root=/dev/sda1 rw console=tty0" -no-reboot (12) BTW, "halt" works at this stage. Population of /dev: crwxrwxrwx 1 root root 5, 1 1970-01-01 01:01 console crwxrwxrwx 1 root root 1, 3 2012-09-11 21:38 null brw-r--r-- 1 root root 8, 0 2012-09-11 21:46 sda brw-r--r-- 1 root root 8, 1 2012-09-11 21:46 sda1 crwxrwxrwx 1 root root 4, 0 1970-01-01 01:02 tty0 crwxrwxrwx 1 root root 4, 1 1970-01-01 01:02 tty1 crw-r--r-- 1 root root 4, 2 2012-09-11 22:08 tty2 Translate it to mknod commands like this: crwxrwxrwx 1 root root 5, 1 1970-01-01 01:01 console becomes: mknod console c 5 1 c = first character of first string; 5 = number after owner 1 = number after that Any comments, addititions or errors are appreciated.
