Booting with a fresh FC4-copy from CD (media is okay, works on a different computer and is checked), I experienced difficulties even getting into the installer. This happed both on a newer server-system as well as on a new desktop machine. When booting a kernel-panic is reported. The servers have motherboard Intel D865GLC, Bios Rev.P24. The desktop machine has Asus P5P800 as motherboard. Installing FC3 worked fine, and I even could upgrade and afterwards use FC4. Is there something wrong related to the kernel used for the installer? Why does this only affect newer hardware? Is this maybe SATA-related? Reading the thread at: http://forums.fedoraforum.org/showthread.php?t=59051 I found: http://forums.fedoraforum.org/showthread.php?postid=284825#post284825 [...] when you get the install screen just type anything and press enter. after that just hit enter again. The Installation will proceed normally [...] For this to work I needed to switch the SATA disk to compatibility mode. Then the installer started fine. Afterwards it reported some more problems - but that's another case imho.
