default off and on-chip RAM areas

Hi Forum

I'm using a LPC2478 with 8 MB external RAM.
In the project option I have reserved the off-chip area RAM1 to be the framebuffer.
Off-chip RAM2 area is the rest of the external RAM. This is set to default.
I also have set the on-chip area IRAM1 as being default.

So my question is. How does KEIL compile my code then? Does it put the const/static stuff in the on-chip RAM first and then in the off-chip, or is it unpredictable where things are placed?

Also, it seems that the framebuffer gets corrupted, when the IRAM1 is not marked as default and only the RAM2 is marked as default?
