    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?

    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.
