See the prior Beta1 release thread here http://boards.openpa...dpost__p__93477
and posts #83 from Dave1234 and post #85 from myself, where I explain where you might want to swap the Kernel over yourself.
Otherwise just use the SD installer as normal, making several partitions and it wil extract the correct kernel from the package anyway. You only need the seperate kernel if you do what I explain in post #85. Hope that helps.
Edit: In case its not clear what I'm dribbling on about.
1) If you wish to erase your NAND and install this latest beta of the OS. Grab the Full flashing version ED has offered and do as instructed.
2) If you wish to make a fresh SD card installation. Grab the SD install version and use it with Dave1234's SD Installer PND and you will create a new SD card with an EXT2 OS partition, a VFAT data partition and perhaps a SWAP partition. The correct kernel will be automatically unpacked by the SD installer.
3) If you've previously used the SD installer and just wish to replace the EXT2 OS partition only with the new beta OS. Then grab the SD Install version ED has offered. Then do not use the SD Installer PND but instead :
a) Format the EXT2 partition to blank EXT2.
b ) Use the terminal to copy the SD Install version of the Beta to that partition. Then untar it. Then delete the tar to get the space back.
c) Grab the Kernel file that ED offers and put it in the root of the VFAT data partition, so you have the correct Kernel to match the new OS beta.
d) If you had a SWAP partition it will no longer be active. So do as Dave1234 says here http://boards.openpa...dpost__p__75814
to re-enable it.
Always nice to have lots of options. I tend to do option 3 myself, as having to manually backup the VFAT Data partition of a large SD card and then re-fill it to the new VFAT partition made by choice 2 is a lengthy process manually. You can use imaging programs which is considerably faster but its still time consuming for me. So option 3 allows for a quick OS partition update and carry straight on, particularly if you tar up the Home dir to preserve many settings aswell.
