how to partition DS5000 using keil c51

Hi,

I am trying to modify startup.A51 with the following chunk of codes to partition the memory, putting it after "CSEG AT 0" does work to some extent. The compiler complains '*** WARNING L5: CODE SPACE MEMORY OVERLAP". Ignoring this I downloaded to my board, i check that the partition is indeed modified, but my interrupts and interrupts can't work anymore.

Am I missing something more ?

What I have cut-and-paste is as follows:

MOV TA, #0AAh ;Timed
MOV TA, #55h ;Access
ORL MCON, #02h ;Set PAA
MOV MCON, #028h ;Set Partition to 5800 on DS5000
MOV TA, #0AAh ;Timed
MOV TA, #55h ;Access
ANL MCON, #0FDh ;Clear PAA

How do you program the DS5000?

Simply use kit to download, I could use kit to partition, but hope to do it automatically using boot-up...

Any experiences on partitioning ???
