changing resolution is to change eeprom values. And I wouldn't have changed itunless you have methods of restoring eeprom if it gets broken.

EEPROM is a serial 256 byte chip, and we let the BIOS do all the communications with it. That should make it as safe as possible - but it will never be 100% safe. All programs that changes video resolution has the same risk, so this is a general warning.

and be careful, if you write to the eeprom too many times, you can fry it. so be careful

but MS refunds the broken ones - as long as it's not modded.

softmod is *especially* dangerous, at least some chips like x3 has ways around the hosed eepom problems. Softmod takes really little to break down, be careful with these things.

OK now I'm getting really confused. This is what someone else told me:

It's my understanding that it switches the value in eprom only when selecting NTSC/PAL. So once you have mode selected with enigmah, that's it, I can't see it writing to eprom when switching resolutions, as this is what the US or Jap models would be doing potentialy a dozen or so times a week during normal use.

This seems to make sense to me 'cause I can't believe MS would enable HD support & the ability to switch resolutions if there would be a fairly big chance it would fry the EEPROM...
