loader=/boot/chain.b map-drive=0x80 to=0x82 map-drive=0x81 to=0x80 map-drive=0x82 to=0x81 unsafe Add those lines to your Solaris section. I guarantee it'l work. The chain.b loader line is needed if the "other" partition or drive starts with a boot loader rather than an os file. A win9x partition starts with an os file, and Solaris definitly has to put a boot loader in the MBR of its disk. Normally only the first two drives can be bootable (0x80 and 0x81) but 0x82 is the third this is why it warns that you may be unable to boot. To fix that, add the map-drives lines above - they tell lilo to make the first (raid) drive third, and the third (4gb scsi) drive second, and the second (jaz) drive first. Why? Because when you installed Solaris, the jaz drive was first and the 4gb scsi drive was second. You are just putting things where Solaris expects them. Hopefully putting the raid drive third will not bother Solaris. Many peope use map-drive to fool windows into thinking its on the first drive when its not. If it fools windows, it may be able to fool solaris. What's the 'unsafe' line for? It tells lilo "Just DO IT!" even if it thinks the solaris boot block in /dev/sdc is not valid. Try it without unsafe, and if it complains, try it with. If this doesn't work, it will be close, and you can try adjustments to make it fit. > > and reran lilo.
