Yep it seems easy enough to find out your own IDPS. Making your CEX to DEX is not so hard either, but only useful if you're a trying to gain more knowledge of the workings of the PS3, explore, develop, etc (and perhaps a few keys :P)
The latest Multiman shows you your IDPS under Information.
I have a feeling all you have to do is change the sixth byte to 82 (or A0 if you're feeling adventurous) and flash it back/use the .self in the leaked CEX-DEX kit to write it back. http://psx-updates.blogspot.com/2011...ps3s-idps.html
I'm guessing it would ylod if you try to boot with retail firmware, so you'd wanna be in F/S mode and use the lvl2diag.self to install DEX firmware, (or you might be able to get recovery mode and do it from there)
I think mathieulh is lying/misleading people into thinking it's SO HARD OMG BRICK to change a CEX to DEX, but no one wants to try (myself included; I don't really need a DEX machine, would be cool to play around with one though)
If you have a flasher you should try

Reason: Oops, 82 not 81
