Hi,
I've just cross-compiled an image for a x86. I copied (dd) the image across from a livecd and then rebooted. It starts to bootup fine until:
Kernel panic - not syncing: No init found. Try passing init= option to kernelAnyone know what I'm doing wrong?
Cheers.

Any ideas? I had hoped this might be a quick one 
What's the difference between the
openwrt-x86-generic-combined-ext4.img.gz
openwrt-x86-generic-fs-ext4.img.gz
images that are produced? Maybe that has something to do with it? I used the combined image.
Maybe I've missed a package I need during "make menuconfig"?
Cheers.
You want the combined image. What command did you use to dd it over to the hard drive? Please post the exact commands you used.
I used:
dd if=openwrt-x86-generic-combined-ext4.img of=/dev/sda bs=1M count=100Thanks for your help.
Hmmm...what type of computer is this? What kind of hard drive? You may need a custom kernel with AHCI sata enabled in the device drivers.
My hardware is:
Intel pentium D processor
MSI P965 Neo motherboard
SATA II hard drive
I just went into "make menuconfig" to check my configuation:

andrew@andrew-VirtualBox:~/OpenWRT/trunk$ What does this mean? Is it a problem?
Ticking the corresponding kmods as <*> in menuconfig will not help as this just means that the package containing the kernel module files is embedded into the firmware rootfs, but since OpenWrt has no initrd facility at all it cannot preload the required modules to find the rootfs. You need to run "make kernel_menuconfig" and mark the appropriate controller driver as builtin so that it is actually compiled into the kernel image.
I'm still getting a Kernel panic:
EXT4-fs error (device sda2): ext4_lookup:1044: inode #2: comm swapper: deleted inode referenced: 3571
Kernel panic - not syncing: No init found. Try passing init= optin to kernel.
EXT4-fs (sda2): error count: 2
EXT4-fs (sda2): inital error at 1358899193: ext4_lookup:1044: inode 2
EXT4-fs (sda2): last error at 1358899860: ext4_lookup: 1044: inode 2Any ideas?
Any ideas? All I want to do is TRY OpenWRT to see if it will fulfil my needs! You'd think that a pre-compiled image for PC hardware would include SATA drivers etc.
Anyway, I've compiled my own kernel with ext4/ext2 and SATA support but it still does not work. Is something broken or should I try including something else into my kernel? If so, what? It kind of seems like guess work to me.
Another question: How can I backup both the configuration for 'make kernel_menuconfig' and 'make menuconfig' (in case I start again from the begining)?
Cheers.
The discussion might have continued from here.
