| I've only now gotten around to upgrading my laptop to a recent
| vintage of kernel (it was running some 1.4X, from ~ 4/30/2000
| previously) and now find that it finds none of the pnpbios-
| attached devices.
Hmm.
| The problem is that the devices offered by the PNPBIOS on my
| laptop (a DEC VP765, if that matters, with PhoenixBIOS 4.0 rel-
| ease 6.0) have empty (zeroed out) static configs.. The PNPBIOS
| code takes that to mean 'device disabled'.
Ugh. Well, that's another problem with this mechanism.
| So, this gives rise to two questions:
| (1) Does the PNPBIOS spec say anything about this? Is my
| laptop somehow violating the standard by not offering
| any resources in the static config?
| (2) Is anyone else experiencing problems with PNPBIOS
| devices claiming to be 'disabled' on their machines?
I think there are issues with this "fix" that I implemented.
For one thing, the pckbc the attachment still doesn't work on the Vaio.
Other laptops seem to have other quirks on particular pnpbios
indexes.
So I think we need some more generic quirk code, and probably
to pull out the static queries and go back the dynamic queries.
But not in time for 1.5.
