=== Linux OSS driver ===
This sound chip is supported by the cs4232 kernel module. Use the following options line when loading this module:

options cs4232 io=0x530 irq=5 dma=1 dma2=0

or try this from the Commandline:

''' modprobe cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=7 synthio=0x330 synthirq=7'''

''=> Dont forget to disable QUICKBOOT in the BIOS and dont INITIALIZE !''

=== Linux ALSA driver ===
This sound chip is supported by the snd-cs4236 kernel module. Use the following options line when loading this module:

options snd-cs4236 snd_index=0 snd_port=0x530 snd_cport=0x538 snd_isapnp=0 snd_dma1=1 snd_dma2=0 snd_irq=5

=== PnP issues ===
This chip is software configurable. In Thinkpads, the BIOS sets up the chip if fast boot is disabled. If fast boot is enabled, the chip is disabled until a PnP driver enables it. As both the OSS and the ALSA module do not support PnP discovering of this chips in a ThinkPad, a configuration script like [[Script for configuring the CS4239 sound chip in PnP mode|this one]] may be used. See also [[Problem with broken sound on some ThinkPads|this page]] for more information.

=== ThinkPads this chip may be found in ===
* {{600E}}
* {{770X}}, {{770Z}}

=== Mixer ===
I loaded the cs4242 module and on my Gnome Desktop (Ubuntu) and the sound work, but was too low when I play music and with the mixer of Gnome was not possible to modify the volume. I fixed the problem installing the mixer of KDE (kmix) and I use PCM to modify the volume.
