To all SuSe gurus,
I am trying to compile a new kernal on SuSe8 and I am having a few problems understanding what to do when I get to : mk_initrd . I want mk_initrd to use boot/vmlinuz-james that I created and not boot/vmlinuz.suse
Use the -k option of mk_initrd. Do a "mk_initrd -h" , there is no man page. -- use Perl; #powerful programmable prestidigitation
Hi , AFAICS ther is no "make modules" in your write up which needs to be done before modules_install Am Sonntag, 20. Oktober 2002 12:33 schrieb jpearson3:

This should be /sbin/mk_initrd -k vmlinuz-james1 -i initrd-james1 -s auto

You probably want to add an "image = /boot/vmlinuz-james1" as well
# label = failsafe # root = /dev/hda2 # vga = 788 # initrd = /boot/initrd
and an "initrd = /boot/initrd-james1" Anders
