I remember hearing that some of the older Sun machines could only boot from the first GB of the disk. Is there any need to have a separate partition at the beginning of the disk for /boot with the kernels and silo in it? Installation was smooth. The only problem came when I was asked to choose the hostname. ;) I did make a 16MB partition starting at offset 0 for /boot, and silo didn't want to find the kernel image on reboot.
