upgrading kernel


one of the first things you’ll notice is that everything seems to be going too fast in 10.4.8-JaS, the reason is that the FSB auto-detection isnt working on the built-in kernel. to fix this and get some nice performance/stability improvements, get the latest semthex kernel from irc.macspeak.net in #kernel


more information about semthex’s work and kernel can be found at his website

once you have the new kernel, backup your old on in / with the following command:

sudo mv /mach_kernel /mach_kernel-backup


once you’ve backed up your kernel, move over the new one and fix permissions:

sudo mv ~/Desktop/mach_kernel /

sudo chown root:wheel /mach_kernel


reboot your system once you’re done, if for whatever reason it wont boot or you get a kernel panic, you can switch back to your old kernel by hitting F8 on bootup after BIOS messages and type :


kernel mach_kernel-backup
