Greetings, I have a RedHat Enterprise 4 system up and running. I am trying to run a variant of the stock kernel that comes with this distribution. I performed the following steps: - Installed the src rpm (2.6.9) - Copied the config file from /boot dir to Linux 2.6.9 kernel src dir - make oldconfig ; make all - Copied the bzImage and System.map file to the /boot dir - In the grub.conf file, duplicated the line that booted up RH 4, and changed pertinent stuff as follows: title 2.6.9-prep root (hd0,4) kernel /boot/vmlinuz-2.6.9-prep ro root=LABEL=/1234 rhgb quiet mem=448M vga=791 Info about my system - a single Xeon motherboard, with IDE bootup disk. When I try to boot up this kernel I get something like the following: "Kernel panic : not syncing. Kernel unable to mount file system...." The only thing I did not do is prepare/insatll a initrd file. Do I need to do that? Am I missing some steps? Any help would be very appreciated. I am attaching my .config file. Thanks you, Aha. __________________________________ Do you Yahoo!? Yahoo!
