Actually the instructions that I followed to build the kernel came from "Custom Kernel Compiling in Debian 2.2" by Jeepsta. I am reasonably sure that I did this correctly because when I do dpkg -l, I find kernel-image-2 Custom.2, my second build.
When you speak of updating the block image in the kernel, I assume that you mean changing lilo.conf followed by the command lilo. I have done this. If I understand you correctly, you have no further suggestions that involve working with lilo. Instead you recommend switching to grub, a program that I have not used, but am willing to try. What concerns me is that in the past, I have had trouble getting rid of lilo in the MBR. I was able to get rid of it when it was installed by older versions of Mandrake by using the Windows recovery console. However this did not work with the version of lilo installed by Mandrake 8.0.It also caused troubles with other partitions. Ultimately, I found a program that wiped by computer clean and went through the laborious and lengthy process of restoring my computer. Although I had backed up most things, I could not back up programs that insisted on residing on the C drive (I have separate data and program drives for Windows to protect myself from the inevitable Windows crashes.) >From that time on, I refuse to have anything to do with Mandrake, which insists on installing its version of lilo.It does not allow the usual skip lilo followed by creation of a boot floppy. All this leads to the question, will lilo -q completely clean out the MBR and allow me to try grub without risking my past troubles? The grub package is not now installed on my computer, but if it is on the installation disks I know how to install it. Am I correct that /boot/grub/menu.1st plays the same role as lilo.conf? And that there is a command equivalent to lilo, maybe grub? Can grub be erased easily if things go wrong? I do not want to mess up my entire computer in an effort to gain CD writing. sidney --- Derrick 'dman' Hudson <[EMAIL PROTECTED]> wrote: > On Thu, Oct 16, 2003 at 06:37:44AM -0700, Sidney > Brooks wrote: > > | In typical linux fashion the instructions don't > work. > | The problem is in the following instructions: > | cd /etc/rc.d > | chmod 755 init.d/* > | cd rc3.d > | ln -s ../init.d/modules.init 05modules.init > | > | The third line is obviously suspicious.
