Running make make modules_install does *not* create any links in my /boot directory, Neither make nor make modules_install is *supposed* to create any links in your /boot directory. Make compiles the kernel and static modules, make modules_install compiles the dynamic modules and installs them in /lib/modules/kernel-version/wherever_they_belong. This is why you then have to either copy the compiled kernel (and supplemental files like .config and system.map, if you want) to /boot. make install (which is a different command than make modules_install) does this automatically, and additionally makes symlinks called vmlinuz and vmlinuz.old (if a previous kernel exists), and updates lilo (if available). If you use grub, if grub.conf is set to load vmlinuz as the current kernel, and vmlinuz.old as the previous kernel, you don't then have to update grub in any way when you have used make install to install your newly-compiled kernel, because make install changes the symlink for the previous kernel to vmlinuz.old, and makes the symlink for the newly installed kernel vmlinuz. Kernels older than the current and most-recent-previous can be added manually to the menu directly. My impression is that you haven't yet run make install.

Therefore implying that there is no /dev/hdA in the system. Is that correct ? If not, and you do have a hda device, the (hd0,0) is wrong and should probably be (hd1,0). But in that case your BIOS will probably boot from hda anyway so grub will never even be launched in the first place. What lives on hda, windows ? You can trivially check this by running 'grub' and, within grub, say 'root (hd0,0)'. It should then reply by saying Filesystem type is XXX where XXX is ext2 or ext3 or whatever you used. If it says something like FAT or yields an error (Selected disk does not exist | No such partition) you have the wrong mapping. Trying 'root (hd1,0)' will then be more successful probably. However, your BIOS would still boot hda in most cases, so you had better look into installing grub on /dev/hda (but without breaking whatever lives on hda) If you have no hda, or if hda is the CDrom, it may be prudent to change the cabling so that linux is on the /dev/hda device. Altough it is possible to boot from the slave drive, but it is more straightforward to boot from the master, and you may save yourself some headaches. Maarten -- gentoo-user@gentoo.org mailing list

And is not referenced anywhere in my grub.conf. If it's to be used, it needs to be called on the kernel line of the grub.conf. And I've got 30 gentoo servers running, without a one having the system.map file copied. Holly -- gentoo-user@gentoo.org mailing list
