[Cooker] Installation method

[Edmond & Elza Cheng]

The latest boot.img forces us to upgrade or install the Cooker from the CD.
I prefer the old image which allows us to use the hard disk as well.
Although, the upgrade does not work for the hard disk installation, there is
a work around solution.  It is very cumbersome to make a disk image and then
burn a CD.  Especially sometimes the disk image is greater than 650MB.

Thanks,
Edmond
