Trying to install FC5, booting from first CD fails with message: "Unknown interrupt or fault at EIP 00010006 00000060 c03a1e80" and this message is endlessly repeated. System is an old Compaq Proliant 2500, with 2 x 200MHz Pentium Pro, and FC4 runs fine. Because of the Proliant's "memory hole", FC4 needs boot parameters "memmap=exactmap mem=640k@0 mem=95m@1m" Has something changed in this area with FC5? What does the message actually mean?
