How do I build the initrd file ? The packagemanager downloaded new kernel files and I found them in /boot (vmlinuz-2.6.18-1.2849.fc6, System.map-, symvers-..., config...) but the initrd file must be build and I have not found good instructions for that.

Hi Sami,
Did you only get source code when You updated ? No pre-compiled kernel-files ? |

Ehm, the vmlinuz file is obviously a binary file... or should be at least considering it's name. The tool usually used to generate initrd is mkinitramfs. Most distributions has scripts that uses that command with correct parameters etc and I'm sure Fedora has some also. But on Pegasos the vmlinuz kernel usually has both the kernel and the initrd in the same file. A Pegasos can't boot with the vmlinux/initrd combination found on Macintosh (as far as I have understood, have never used a Mac myself).
Doesn't the kernel you already have in /boot boot? |

@Gunne
I got precompiled kernel files, but not initrd.
@kozz
The current kernel does boot, but I'd like to learn more Linux and upgrade the system. The new kernel does not boot with the current initrd. I'll try mkinitramfs tonight. |

Sami,
So you can't boot the file vmlinuz-2.6.18-1.2849.fc6 from the Pegasos firmware prompt ? |

I find mkinitrd (no mkinitramfs) command but it results "No modules available for kernel "2.6.18-1.2849".
Here's full listing of files in /boot:

How do you boot the system by now ?
Do you load the file vmlinuz-2.6.18-1.2798.fc6 from the Pegasos firmware prompt ?
I think it was about a year ago I booted Fedora on the Pegasos. |

I use grub menu (modified from your Ubuntu installation menu):
linux (hd0,0)/vmlinuz-2.6.18-1.2798.fc6 root=/dev/VolGroup00/LogVol00 video=radeon:1280x768@60 quiet splash
initrd (hd0,0)/initrd-2.6.18-1.2798.fc6.img
If I try to boot the -1.2849 kernel I just get Kernel panic with everything I've tried. |

| Hmm, yes I remember it was some special way needed to boot Fedora. Will read about it tomorrow. Strange that You didn't get the initrd with the update. |

| The modules are located in /lib/modules, see if the modules for your new kernel are located there... otherwise you probably miss some package for fedora with the modules. |

Sami,
Ok, some delay might have occured as it seems.
Here is a guide I found explaining how to compile a kernel - The Fedora way. LINK |

Thanks,
everything works now and I'll some day try to compile the kernel myself. |
