Right... kinda fixed it myself!
I did ONE n00b-ish thing wrong and that was not turn off 'Joilet' files when burning with Nero.
I managed to flash the chip with the Evo M8 Bios, however its not the 1mb Version, but the 256k.
When I tried to flash the 1mb, I got 'flash to small' (I presume this is because there is 2 banks of 512K? even though there is no switch) so I decided to try the 256k version and now I have XBMC!!!
A few notes, my chip has 'Xshadow' on the back of it and is blue unlike the white version on the MuppetX website. Also I have NO swith on my chip unlike the white one.
Can anyone see any reason why I should flash my BIOS again? or am I ok with the 256k version.
At some point I will do a gudie for this chip, as its nice and cheap, and with my knowledge should only take 25-30 mins to install.
Anyone want one of my 13 coasters I made?
If anyone has any question let me know!
