Hi,

I'm new to Linux ( < 1 year ) .. But I'm am experienced SVR4 and AIX
UNIX developer.

There are certain areas of Linux build / boot sequence that I'm not quite
sure
I understand and it is vaguely docuemented for a Intel boot sequence.

I'm curious to what these files are after a Linux build
found at /usr/src/linux are used for by lilo :

arch/i386/boot/bzImage
vmlinux
System.map

There is also another strange step in making a "ramdisk" using

mkinitrd -v -f /boot/initrd.<myver> 2.4.7-10custom.<myver>;

I think that whatever lilo boots is a combined file of Linux (vmlinux? )
and a ramdisk ( initrd) that eventually starts Linux from the harddisk.

Bascially,

I'm trying to add a new boot driver to the startup ramdisk and I can't
get it included. Nor is it built included in the kernel when built.

Can anyone reference a detailed writeup on the Intel boot sequence ?
I poked around RedHat and Sourecforce, but haven't found anything
but general descriptions.

The 22.3.1 tarball includes quite a lot of documentation. I've
read it once but haven't compiled a kernel in a long time. This
is a recent (16June) upgrade btw, with significant changes.

If I remember correctly bzImage is a just-compiled kernel which
can then be copied to /boot/whatevername but when lilo is run it
must be given that name with image=xxx in it's config file.

vmlinux or vmlinuz are 'traditional' names for this usage,
you can have several such as mykernel-a mykernel-b and set
up optional kernels to boot with on this basis.

Multi staged booting for sure. When lilo is run it writes
a map file but that's where I have to get off before making
a complete idiot of myself.

HTH
