i######################################################################### SILO Sparc linux load--- If you have Linux and Solaris on different disks, then just do: boot disk1 to boot Linux with SILO and boot disk2 to boot Solaris (of course, replace disk1/disk2 with actual PROM identification/aliases of your disks). Currently the best way how to make SILO even work with Linux and Solaris on the same disk is use silo -t to put SILO bootblock on the Linux partition, so then you boot boot disk:a to Solaris and e.g. boot disk:f to Linux. If I find some box with Solaris I'll able to play with (currently I have no Solaris around me), I'll make sure the /boot/old.b method works. The other method (solaris keyword) should be dropped, it will not work correctly. It worked once with Solaris 2.4 when I wrote it, but AFAIK it no longer works, especially on sun4u it cannot work. ################################################################################## SILO (you may already have started a note on silo ?) Boot from floppy to rescue. Mount the root partition and check to see if there is a valid /etc/silo.conf file. If not try entering one by hand using 'cat > /etc/silo.conf' and enter something like below, adjusted for your system (partition, root, image name): timeout=50 partition=1 root=/dev/sda1 image=/boot/vmlinuz label=linux root=/dev/sda1 read-only silo is a boot loading code for sparc. It is loaded right into nvram and contains options that can be applied for certain desired effects. What are those options ?
