I spotted a few conversations about such a senario however it appeared things were talking about rh7.x.. I'm assuming a few things have changed since then given the comps.xml etc etc.. and from what I can gather rh8 seems to use stuff in isolinux.. Anyway, I've managed to create my own custom cd, however I need to add/update a kernel module.. Once the system is installed, it has the correct version.. however I'm guessing the kernel that the installer runs with is slightly different.. I need to support the following: megaraid: v1.18c (Release Date: Thu May 16 10:27:55 EDT 2002) Once the system is installed, it actually has that version in the kernel.. I gleaned that from the src.rpm for the kernel package given it contained the following file -- linux-2.4.18-megaraid.patch So this brings the stock kernel up to 1.18c. However I have actually installed the latest kernels as per redhat and it's actually up to 1.18d -- good times..! megaraid: v1.18d (Release Date: Wed Aug 7 18:51:51 EDT 2002) kernel-bigmem-2.4.18-24.8.0 So my questions are...: 1. How can I check what the kernel on the installation media is using 2. How can I update the kernel to be a newer one with the megaraid driver I want! Regards, ajt.
