build kernel problem

[Jennifer]

Hi, I am newly getting to start to learn Debian, and try to get Debian working on my PC.   I used Debian 3.0 Woody CD set (7 of them) to install. And the kernel version is 2.2.20. For I need to install Oracle9i on this Debian, so I need to upgrade kernel to 2.4.xx I downloaded "kernel-image-2.4.21-2-386_2.4.21-2_i386.deb" from Debian site. And I copied this image file to /usr/src/ Then I cd to /usr/src I ran the command " dpkg --install kernel-image-2.4.21-2-386_2.4.21-2_i386.deb". The console told me the following error message:   You are attempting to install an initrd kernel image (version 2.4.21-2-386). but you do not seem to have a mkinitrd command in the path. This will break the installation. I am aborting now. Could not find mkinitrd in path at /var/lib/dpkg/tmp.ci/preinst line 165.dpkg: error processing /usr/src/kernel-image....(--install)   So I used command of "find / -name mkinitrd". And there is no result. I also used "man mkinitrd", and it says no man entry for mkinitrd.   In this case, what should I do?   Your advice will be highly appreciated. Thank you very much.   Jennifer Z
