"hello world" with 18f6680

[Archangel]

and the fuses are set as:

OSC "HS"
<font color=red>System clock "disabled"
</font color>power up timer "disabled"
brown out reset "enabled"
brown out voltage "2.0V"
watchdog timer " enabled"
watchdog postscaler "1:128"
ccp2 multiplexed with "RC1"
mclr pin function "reset"
overflow reset "enabled"
LVP "disabled"
boot block "not protected"

i'm using microcode studio, mpasm and an epic programmer.

What does it mean system clock disabled? Does this mean no oscillator?
