I have an older ARM laptop that I have been beating my head against the wall
trying to install BSD. Most everything works, including I finally got
Xwindows to run after tweaking about 19 different settings, however I have as
yet had no luck with the built-in ESS sound.
I have built several kernels, finally resorting to using a kernel with
userconfig, intro_userconfig, and visual_userconfig defined to I could verify
the presence of the pcm driver, which according to HARDWARE.TXT /should/
support the ESS 1878 which is what this laptop claims to have. Userconfig
does show the pcm driver in memory, but that's it. there is no "pcm0:" line
while booting, (or in dmesg afterwards, either).
The only clue I can come up with is the following lines from dmesg:

pnpbios: bad pnpbios checksum? That shouldn't affect the multimedia stuff,
should it?
but the real interesting line is the chip1 line....
isn't 8086 intel? but what is device 1234? anybody? My best guess is that
the ESS chip is somehow "hiding" behind this chip, and since nothing is
loading for it, pcm never has a chance to see it. (unless it is related to
the bad pnpbios checksum?) I know it isn't the ISA insterface, because 1) I
get the following output 7 lines further down:
isa0: <ISA bus> on motherboard
fdc0: <NEC 72065B or clone> at port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on isa0
(followed by several typically ISA-mounted things like keyboard, mouse,
generic vga interface, all stuff I get on my desktop machine.)
am I missing something obvious? My first thought was a pci-isa bridge, but
it seems to be finding that OK, or at least, otherwise working it OK. Is it
possible that the ESS is really an "ESS compatible" sound card built into the
Intel chipset, and that's why it isn't finding it ( i guess in that case I
could add the appropriate ID string to the appropriate place in the pcm
files, and it might work?)
have I asked enough questions yet for one email? <(}: At least they are all
related to the same issue.
TIA,
mike
