You have to use BSD-disk label to repartition if you want to boot
from hard disk directly.

I think you have to type in the entire boot command every time you switch
kernels. There is no such a boot menu for SRM. You can only save one boot

BSD-disklabel can recognize up to 8 partitions and you can use aboot to
boot any of them. The problem with current released aboot-0.5-10 is that
it can not boot a partition whose offset is higher than 4 GB. I can send
you a revised copy of aboot if you like.
>>d) Just out of curiosity: What does SRM need the 3 MB for (and why isn't

The 3MB is reserved to store aboot, the boot loader to load kernel. SRM
doesn't know about partitions and filesystems. It just knows a fixed
position in the disk where it can load the boot loader.
