Boot Fedora 4 from install or rescue cdrom

[Tomas Srb]

Pls, when my computer (3GHz, Intel P4, 512MB RAM, 2x120GB SATA) start
booting from install or rescue cdrom burned from images
(download.fedora.redhat.com, sha1sum OK), system cannot found ramdrive
image and crash with kernel-panic. Can you tell me, what I do bad ?

This do only with FC4 boot - FC3 start correctly, but I need install
lastest version :-(.

Thank you very much,
	Tomas
