RGM> ron So all linuxbios does is the lowest level of functions to initialize the hardware, such is init RAM, PCI, GFX, ... . And the OS itself have to do the rest; such is sending data to e.g. hd directly through out/in commands to port. They have to code thing like "read sector xy from hd". This is what the BIOS INT functions does normally. Is this roughtly right ? ciao.
