[ltp] Fedora Core 1 | ALSA | setpnp ...almost there

[Darren Hoch]

Hello All,

I have been reading the hundreds of posts about ThinkPad 600e's, setpnp, 
tpctl, ps2.exe, ALSA, and the associated headaches. I never had any 
issues or had to change any BIOS settings with RH9 (used sndconfig) or 
SuSE 9.0 (great tutorial on SuSE's website) with the stock cs4232 
driver. When I installed FC1, everything came apart. I know there are 
plenty of workarounds for every other distro of Linux out there. I am 
looking for anyone who has the magic (detailed) steps for the 
combination of FC1, setpnp/tpctl, and alsa snd-cs4236 or the stock cs4232.

1) I am using the pre-compiled Alsa packages from www.freshrpms.net 
(cool site). I used the alsaconf utility which gave me the following 
/etc/modules.conf:

alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-cs4236
alias sound-slot-0 snd-cs4236
options snd-cs4236 port=0x530 cport=0x538 isapnp=0 dma1=1 dma2=0 irq=5

Should I be taking the settings from the last line here and feeding them 
to setpnp?

2) The only error I had was that the alsaconf utility could not locate 
rcalsasound utility. I then rebooted the machine with an interesting error:

ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996
ad1848: No ISAPnP cards found, trying standard ones...
cs4232: set synthio and synthirq to use the wavefront facilities.
cs4232: Must set io, irq and dma.

Which leads me to believe that I have to do something with the "Quick 
Bios" and the fact that somehow I am calling the cs4232 even though it 
is not in my modules.conf anymore. I have a pretty good understanding of 
interrupts in the SPARC/Solaris/PROM world, but fall short in the BIOS 
world.  I disabled "Quick Bios", but can't really find a post with the 
correct settings to setpnp/tpctl to hardcode the BIOS outside of being 
refered to the sourceforge link or that everyone grumbles about ps2.exe.

3) Here is an lsmod after reboot:

ep snd-mpu401-uart snd-rawmidi snd-seq-device]
soundcore 6468 1 (autoclean) [snd]

4) It appears that the modules loaded correctly. Using the alsamixer 
followed by the gnome-alsamixer gui, I unmuted (including PCM) 
everything and cranked up the volume. I tried the stock Gnome CD player 
and the alsaplayer to play an MP3. No Sound.

I guess I need a little lovin' on the whole PnP side of things. I am 
trying to deploy FC1 across multiple ThinkPad 600e laptops and I am 
trying to stay away from compiling source.

Thanks in advance for any help!

PS- I can offer some of my own tutorials/scripts/packages @ 
www.ufsdump.org in return for help. Also, I am willing to write up a 
nice tutorial on this experience.
