correct direction, thank you for you all !


Lots of good information has been provided by other. Here is
another approach., I do not have the link handy, but you can
look at the docs and there is a place that tells you (steps)
how to copy the kernel that is provided on the installation
cd/dvd to use an your initial boot kernel. It should work,
but maybe with lots of extra stuff you do not need.

Then you can use grub to have several bootable kernels, the
one you actually boot off us is selected a few seconds after
you power up. This way you can get your system working (bootable)
and then take you time pruning the options and learning about
building kernels.

It's easy, here one of my /boot/grub/grub.conf files:
(this one even will boot a doz, if that is installed too:


default 2
fallback 1
timeout 15 
#splashimage=(hd0,1)/grub/splash.xpm.gz

#0
title=kernel-2.6.36-gentoo-r8
root(hd0,1)
kernel /boot/kernel-2.6.36-gentoo-r8 root=/dev/sda3 video=1024x768
#1
title=kernel-2.6.38-gentoo-r6
root(hd0,1)
kernel /boot/kernel-2.6.38-gentoo-r6 root=/dev/sda3 video=1024x768
#2
title=kernel-2.6.39-gentoo-r3
root(hd0,1)
kernel /boot/kernel-2.6.39-gentoo-r3 root=/dev/sda3 video=1024x768

Let me know if you have trouble finding that link for copying the
kernel off of the install media to you hard drive.

hth,
