it doesnt even boot. it just a bunch of writing and it says "OS NOT YET SET"I don't think the sequence matters for those options. I don't remember now what sequence I used but either one should be OK, as long as all 4 options are there.
i just decided to say **** it and do a clean install i think the previous nvidia drivers were messing with it.I would remove the nvda_drv=1 and try it again. Where that's coming from, though, is a mystery... if I had to guess, it's a Kernel Flag setting in the /Extra/org.chameleon.Boot.plist file on your USB drive.
IIRC the nvda_drv=1 option is only necessary if you're using Nvidia's drivers. At this point in the install you're still using Apple's drivers so you shouldn't need that option.
