I'm in the same boat as this fellow. Everything seems to be operating fine (I can boot NSMB from my 2GB USB jumpdrive) but I have an 8GB SDHC (SanDisk) card that I need to utilize in order to boot ISOs larger than 2GB (most of them).
I am new and have been doing my best to read these forums before asking.
Any help would be appreciated.
edit: also, if you can't help me with the problems above, what ISOs are out there that are under 2GB (post-scrub) other than NSMB?
