Has anyone everyone convert a program written for the IAR compiler to be written for the Keil compiler.

I am converting a very large program and I am having a very hard time. I have 8032 development board with 256 internal Ram, 32K external Rom, 64K external Ram.

I am getting tons of Errors like "Address Overflows" and "References made to Erroneous external". The map file from IAR version uses only 10K ram and 30K rom. I am thinking I am not including the necessary linking files to uses 32k external rom and 64k external rom.
