After reading Melanie fuses thread and some posts by Bruce for the 18f4550 im pretty sure this modification to the 18f2550.inc file in pbp subdir should work, I want to run the program at 4mhz with the internal oscillator, all ports digital, no clock out, no brown out detection and my app is not USB related, please correct me if Im wrong:

Code:
;****************************************

                NOLIST
    ifdef PM_USED
        LIST
        "Error: PM does not support this device.  Use MPASM."
        NOLIST
    else
        LIST
        LIST p = 18F2550, r = dec, w = -311, f = inhx32
        INCLUDE "P18F2550.INC"	; MPASM  Header

        NOLIST
    endif
        LIST
EEPROM_START	EQU	0F00000h

Thanks in advance!
