OK. I just enabled CONFIG_BLK_DEV_RAM and CONFIG_BLK_DEV_INITRD in the kernel config file and rebuilt the kernel. Now I am getting a repeated (again and again) message modprobe: modprobe: Can't locate module net-pf-1 As I mentioned before the /boot/config file was garbage on my RH9 install and I am having to go through the .config file carefully now. > > > My old /etc/lilo.conf file (which worked fine) had the > > following line in it (as does the image section for my new > > kernel): > > > > append = "hdc=ide-scsi root=LABEL=/" > > > > I am not familiar with what this line is doing.
