I have a Dell Latitude CP (laptop) here with such a beast in it. It took me ages to get the sound going with the kernel sound driver - but I finally did it :) It's running RedHat 5.2 (standard kernel from the install), but I have no idea how "generic" this solution is. The most important thing is to get /etc/conf.modules right. This is what I have in it... # turn off unwanted net stuff... alias net-pf-3 off # no ax25 alias net-pf-4 off # no ipx alias net-pf-5 off # no appletalk alias net-pf-6 off # no netrom # for the CDROM... alias iso9660 isofs # sound driver alias sound cs4232 options -k cs4232 io=0x530 dma=1 dma2=0 irq=5 # no midi yet :( This works for the audio driver, but I have yet to get the midi to work. (Any hints on how to do this would be most appreciated - please Cc any replies from linux-laptop as I'm not subscribed to that list, thanx). Cheers Tony
