RE: [OpenBIOS] Starting Linux from the C environment

[Stawnyczy, Evan]

well this was my argument in the begining, we should allow this BIOS to
support "REAL" bios calls like int 13 and int 10...  if you include basic
BIOS functionality, you can allow any "decent" operating system to
startup...  including LILO

Basicly you are right. But lilo makes extensive use of *real* BIOS
functions like int13, int10, int16, and some strange
int15-shift-this-memory-to-ems function that I forgot the functioncode of.

I´d rather do this in C and burn a barebone Kernel onto my Disk ...
    But I´m not sure if I kill my own running environment by copying a
Kernel to mem at 0x10000. Furthermore I have no idea if the
segment-deskriptor-setup is suitable for an immediate start of a kernel
image ...

I´ll try this tomorrow and keep you up to date if I succeed on this
...

Ahh but if I remember back at the beginning of the list the point of openBIOS
was to get rid of the BIOS calls and boot 32bit OS's in 32bit mode, the though
being that most OS's don't use the BIOS calls, except when first booting.....
Of course that concept can deliver a whole new selection of problems...  I'll
leave the rest to you .. ;-)

That is why I included "BIOS interrupt calls" on the short list of
important tasks, posted recently.  :)
