So In yesterday’s post, I posited that a custom chip from Apple might make it impossible for people to port other operating systems to the iPad hardware.

It turns out, according to this artice over at Bright Side of News, the A4 is simply a system on a chip. It is an ARM Cortex-A9 MPCore CPU mashed together with memory and other functions.

Porting something like linux to the iPad won’t be easy but it should be possible. As far as I know, no alternative operating systems have been successfully run on the iPhone and the iPad will probably have a very similar story. Theoretically, iBoot from the iPhone Dev Team is close to getting an Linux to load on the iPhone. Let’s hope they can bring some of the same know-how to the iPad.
