In a conversation with enatefox recently he asked if it was possible to dualboot an android phone, I thought it was and set out to make that happen. This is that work.

This is a VERY EARLY BETA! It does function, but its rough. Don't expect this to be smooth or easy yet.

This image is based on Amon-RA-v1.6.2

What you need to do:
This hack will boot a rom from SDCard. It expects to see system.img and data.img on the sdcard as well as init.rc.

System.img needs to be a disk image of a filesystem that the kernel can read(I've been using ext3) around 170MB(Thats the Eris's NAND size for system)

data.img needs to be a disk image of a filesystem that the kernel can read(I've been using ext3) as big as you'd like your data partition to be(This holds your apps etc, so a couple hundred megs is good)

init.rc needs to be the init.rc of your rom with two changes
You need to remove the lines where it mounts /system and /data.

Once you have those three files on your sdcard, and have flashed this recovery you're ready to try your first boot.

Reboot into recovery, you'll see the normal usual recovery menu(I'll add an item eventually)

connect to the recovery console with adb
run 'adb shell /bootfromsd'

It will APPEAR to have done nothing for a bit, this is normal. Its booting your rom now. Once it gets to the place in the rom where it would display the splash screen, you'll get a splash as usual. You can watch it with logcat if you like.

I've personally booted the following roms from SD.

KaosFroyo
KaosLegendary
CELBFroyo
MR4
PlainJane

Good luck!

So do the roms you load from SD run just as smooth as a normal one?

depends on the speed of your SD. Theres a tiny bit of lag on the class 2 I tried it on, but it would likely be fine on a faster card.

this as well as the herculean update schedule of KaosFroyo convinces me that Punk.Kaos should have his own kids show.

"But Punk.Kaos! that's impossible!"
Punk.Kaos appears in a superhero outfit with a silvered cape, poses and says,
"No little Jenny. Impossible is only what we have yet to try."
