Hi all, I have D865GBF/D865PERC Desktop Board with 1024MB Kingston Ram. I downloaded DVD and CD iso images. I checked sha1sums everything was ok. I burn DVD and CD isos. When I tried to boot my computer it gave some errors and did not boot. I tried that DVD and CD an other computer I worked. I tried to boot FC3 in my computer it boot again. I think there is a problem on initrd and vmlinux in isolinux directory. I will try to merge FC3 isolinux and FC4. And then i will try to make a bootable DVD. Do anybody have an idea about this solution and problem? Thanks All Caglar Ulkuderner System Administrator / Computer Engineer, TUBITAK
