Yes.

No. The root partition must be specified like ``wd(1,a)'' and you have
to specify the bios drive number as well, e. g.

	boot: 1:wd(1,a)/kernel.GENERIC

to boot from the second bios drive (``1:'') which is the slave
drive on the first IDE controller``wd(1,a)''. But you probably don't
want to specify bios drive and root partition at all, so just enter

	boot: kernel.GENERIC
at the boot: prompt to load kernel.GENERIC.

This is done by the ``install'' target of the kernel make file. The /kernel
is moved to /kernel.old.
