OpenBSD/sparc: which drive spec should I trust?

[Nebu John Mathai <mathai_(_at_)_ecf_(_dot_)_utoronto_(_dot_)_ca>]

Hi,
I ran into some confusion with OpenBSD/Sparc.
When it boots up, it reports (paraphrased)
sd0: ... Sun0424 1476 cyls, X sectors, etc
sd0: Sun411 1150 cyls, Y sectors, etc

I think the reference to Sun411 1150 cyls is from OpenBSD's disklabel
(because when I run disklabel that's what I see). Question is .. where is
the first reference (the 1476 cyls) coming from?

Thanks  for your help
