Edit the file /boot/grub/grub.conf On the kernel line append this to the end of it rhgb
Like so...
title Fedora Core (2.4.22-1.2135.nptl) root (hd0,0) kernel /vmlinuz-2.4.22-1.2135.nptl ro root=LABEL=/ hdc=ide-scsi rhgb initrd /initrd-2.4.22-1.2135.nptl.img
"Please note that the lines may wrap, the kernel line is ONE line"
Add a "quiet" after "rhgb" and it'll look even nicer during boot-up... (less kernel debug messages...)
