booting live cdrom from a iso image on hard disk

Folks, Can I boot up the live cd without burning it to a cd? The live-xxx.iso is on my hard drive (FAT), and I wanted to use the boot floppy to boot up, and mount the iso as root in loopback mode. I know know this works if you have a CD burner, but I don't and I only want to experiment a bit before installing suse. I have a problem with redhat 7.3 stability (compiling kernels or anything crashes the compiler with Sig 11 errors all the time--1 or 2 times a minute.) I wanted to try the suse live cdrom before replacing my while os. Hasan
