Problem with xdata const

Hello,
I try some like this:

xdata const char table[]={"BBBB"};

to place consts in ext. ROM.

Everything is OK,
but i get only ONE hex file.

I need hex file to burn internal flash ROM in 89s8252, and another hex to burn external
data rom. How can i make two hex file from
OMF2 file?

Is this possible?...
