I have been using core-image-sato and core-image-sato-sdk on the hard
disk on Intel Atom (crownbay in my case).

I perform the following broad steps:

1) have a suitable partition on the disk - say partition #3
2) this partition will show up as sde3 on my host machine and sda3 on the atom
3) mkfs.ext3 /dev/sde3
4) mount /dev/sde3 /mnt/target
5) mount -o loop tmp/deploy/images/core-image-sato-sdk.ext3 /mnt/target-text3
6) cp -a /mnt/target-ext3/* /mnt/target
7) grub-install --recheck --root-directory=/mnt/target /dev/sde

If grub install passed, I copy the following to /mnt/target/boot/grub/grub.cfg

set default="0"
set timeout="30"

menuentry 'Yocto SDK' {
insmod part_msdos
insmod ext2
set root='(hd0,msdos3)'
linux /boot/bzImage root=/dev/sda3

Thats it - this boots for me.

Eventually, when I move to some other media, I will have to
investigate other bootloaders - like syslinux.

All the best, do tell if this works.
This worked fine for me. one typo in step (5) ext3 and not text3, but these are good instructions. How do we get them put into the README.hardware instead of the directdisk section that doesn't work anymore.

Did you file a bug on this?

The README.hardware file in the poky directory talks about creating images
on 2 types of disk for the Atom based PCs like the n450. The one I've
successfully tested is the core-image-sato on a USB key. I have no luck
with the directdisk method because the image recipe doesn't exist for
core-image-minimal-directdisk or core-image-sato-directdisk.

Is there a way to put Yocto on the hard drive on a Atom PC?
