easy way to cause lock-up (ie no reset capability)

I was hoping there was a simple way to disable the reset button, but I guess I wasn't so lucky! I'm trying to find an easy way to debug code flow of elf's I'm making, and was wondering if there was a simple instruction or couple instructions I could edit into the assembly code to lock-up the PS2 (ie...

Disable the reset buttons from EE??

Hi,

does anyone know if it's possible to disable the reset buttons on the console from the EE side? (I've noticed some home made apps like execftps, etc. disable the reset button)

Is the reset button an int to the IOP, or can it be seen at all from the EE side??

thanks!

identifying calls to IOP from EE?

Hi there, I have somewhat of a general question I think....I'm pretty much a noob to this scene, but I've been trying to follow some already developed code to help myself learn... Is there any way to figure out what calls in an EE file are going to the IOP??? ie I have the IOP file disassembled and ...
