[idea] two ROMs on one device (aka dualboot)

[Guest Sulthekk]

Finally got success but partial.I have successfully booted ics from sdcard and it is fast as NAND .Soon will create thread.

That's good to hear. Does partial succes mean that you have repacked the boot.img with the root and/or loop parameters pointing to the fs on the sdcard, and then placed the system manually there?
