    developing simple bootloader which calls linux kernel


    Hi all,
    I want to develope my own simple bootloader which do nothing but calling my linux kernel. I want to do this like LILO whithout file system, but I don't know how does LILO find kernel's physical address. I know LILO stores kernel information in /boot/map file, but map is binary and I don't know it's format and how to decode it. Help please.. Is there any detailed manual?

    sorry for my poor english.
    Thanks

    I have only one operating system, and I also have initial ram disk (initrd). I don't know how LILO passes the initrd address to the kernel.

    Have you had a look at the lilo source code?
    What do we want?
    Time machines!

    When do we want 'em?
    Doesn't really matter does it!?

    Yes, but it's complex and has many headers and source file.. LILO has many options which I don't need
    I don't need any menu, I only want to jump to kernel from MBR (I want to develope my own simple linux loader). But I don't know where is the CHS (Cylinder/Head/Sector) address of kernel.

    Hi, try to look at syslinux. It would be even more lightweight than LILO. Otherwise I cannot help as I don't have any experience with developing bootloaders.
