Among plug and play problems, this seems to be a rare one. I get the
above message both at boot and from pnpinfo.
My OS is 2.2.7-RELEASE with corresponding PAO patches. The computer
is a NEC Versa LX (a laptop). I gather it may be significant that
while in my hands this machine has never booted Windoze---the first
thing it ran was 2.2.7's boot.flp. It seems Windoze can play a
critical role in making pnp devices available, so perhaps this was a
foolish move.
The specific device I'm trying to get working is my sound chip, which
has been variously described as an ESS 1918 or ESS Maestro 2.
However, the BIOS suggests that various other devices (serial,
parallel, IR port) are PNP as well, so I'm really surprised that
pnpinfo can't find a single thing. Do I need to do the `pnp x y os
enable' dance before pppinfo will see a device, or should it work
regardless?
The sound chip in question is also PCI, it seems. At boot it is
described as follows:
pci0:4: vendor=0x125d, device=0x1978, class=multimedia (audio) int a
irq 5 [no driver assigned]
Frustratingly, there are no BIOS options pertaining to PNP, not even
the usual `PNP operating system? Yes/No'. Nor are there any options
pertaining to the sound card. It is most frustrating; I'd be very
grateful for any light anybody can shed. I've appended a dmesg below,
in case that would be helpful.
