You need to get a smaller image , you do not have enough dram to support the image.

But it used to have this image only on it before...anyways I'll try a smaller image..

thanks..it worked...Is the larger image going to be supported if I alter the IOmem size??

You have to look at the system requirements when you download it from CCO. It will tell you the "minimum" requirements needed for dram and flash. Changing IOM is not likely to help. The show version command tells you how much dram and flash you have in the box and compare that to the system requirements.
