Hiyas IA Hackers,
At least you're able to get the removable Smart card booted if i understand your issue well, in your case it might be just a matter of making the sandisk bootable for the device, best way is probably Ranish partition manager. I am not particulairy fond of the default MS tools for it, most third party tools work much better(read less limitations). The eltorito image is probably already active as bootable, question is, is the image bootable, command com, Zbeos, or Zlinux Kernel or any other. my general knowledge goes as far that there must be a pointer towards the Kernel of the image you're trying to boot.
If you're able to load the Be image from CF disk/card you might want to use Drivesetup from BeOS Pe, it's more powerfull than the WinOS tools, very close to ranish only with a GUI. I use it primairely for making any partition or disk preps for a number of OSes.
You could also use a a Zbeos image of the bootfloppy which can be used the same as eltorito.
As soon as i can make my CF card bootable then i'll probably be in business and use BeOS for the device. Later i'l try to set up a small bootloader and minmal OS on the internal sandisk and be able to boot a veriety of OSes from removable CF disks what i prefer.
Most of them can work that way if you make a minimal footprint with only the drivers that you need.
I was also thinking of looking at a SymbianOS partition since i have a series 60 Nokia also, probably need some tweaking on driver level but there are more than enough tools and 3rd party software to do that.
With kind regards and respect,
