[LinuxBIOS] FILO problems with an NCD ThinStar terminal

[Adam Nielsen]

Ok, promising update:

I disabled "GRUB" in the config file, hoping that would ignore the
menu.lst, which it did, and it then gave me a boot prompt, and most
amazing of all, it doesn't lock up when I type at it :-D

So, step two is figure out how to get it to boot something.

I tried embedding a Linux kernel in the same manner as the menu.lst, but
I got a warning that I was overwriting stack space in the ELF file, so
that may explain the problem I was having before.  However I now tried
to get the kernel image to load at 0x400000, and readelf shows that
everything is what I expect it to be, however FILO says it doesn't
recognise the image at that offset (when I do it as ELF or a straight
bzImage.)

So now I'm stuck again, but it looks like it's my method of embedding
files into the ELF image that's the problem - can someone point me in
the right direction here?  Google's not being too helpful for me with
this.

Thanks,
Adam.
