Here's the solution found for the Kernel Panic case that happens when booting the CD/DVD of FC4 to launch install. You get Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,2) or VFS: Cannot open root device "<NULL>" or unknown-block(3,2) try this: 1- at boot: prompt just type in some random crap 2- validate, the system will just give an error 3- at the boot: prompt again, just press enter Then the install shall run fine ... weird ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
