Where you able to get the N810 booting from external finally? I'm fighting with mine now with the same initial results; N800 flashes clean and boots without issue but the N810 consistently returns "boot failed, booting from internal flash". In my case, 256 meg of root partition takes about an hour to fill with only a part of my usual program installs. 2gig internal is far from an acceptable amount of storage; I'd get a 1.5 gig root partition and a .5 gig fat32 out of it but still not enough room. The ending kicker for me is that I want to wear out removable mmc media rather than blowing through the limited read/write cycles in my non-removable storage. If you managed to get it working, could you point me towards the HowTo or let me know what the few alterations to the N800 process where? (I love what I am going to be able to do with the hardware but I gotta get it built right first since Nokia decided to cripple it with limited storage)
