1: This is a kernel config question, not one of Fedora Legacy support per se. for a clue: grep RAM /usr/src/linux-x.y.mumble/.config 2: RAMDisks, by definition, are in RAM, not on a hard drive; a 12GB RAM disk would consume 12GB of RAM space. I doubt you have 12GB of physical RAM. Virtual RAM (which is on the hard drive, and thus not much faster than a simple file on the hard drive) could be used, if you have 12GB of free phys+swap Memory Space. 3: You can make a fake RAM space of any size using a loopback device. Before going farther, can you explain why you need a 12GB RAMdisk?
