Just a thought - when I compile and installed my own kernel, I used the zImage kernel. I played with make-kpkg, and this wants to put the files vmlinuz & vmlinux in /boot. Would using zImage instead of vmlinux cause problems? How do I produce vmlinux from the kernel source?
BTW, I can't see any install options in the kernel makefile. I just followed the instructions in the readme, which were to: make config make clean; make dep make zImage make modules make modules-install cp arch/i386/boot/zImage /boot modify lilo to include /boot/zImage The README doesn't mention anything about System.map :( Thanks for any information, Chris On Sun, 24 May 1998, Bill Mitchell wrote: > Off the top of my head --- > > That file gives the memory addresses of symbolic variables used in > the kernel.
