One more thing:
If your disk is the master on the secondary EIDE chanel (i.e. wd2), this
will still probably not work for you. At the end of the kernel startup
you'll get the "panic: cannot mount root" message. In this case your
only chance for 2.1.0 (if I remember correctly) is to build a kernel
with the line:

config kernel root on wd2

in it. You'll need to move your drive to another position to do that.
For 2.1.5 and above you'll be able to boot with 1:wd(2,a)/kernel at the
boot prompt, but I think this will not work with 2.1.0.
