I have Yamaha YMF-724 PCI sound card. The only way to make that card work in linux is using OSS driver from Open Sound System. But i have a problem when I try to install that driver: 1. I have an error message during install about kernel incompatibility, and refer to OSS documentation, I must recompiling my kernel and enable "CONFIG_MODVERSIONS" using "make" command. But when I try to type that command, linux said that make comand is not available. And I was confuse too about how to enable CONFIG_MODVERSIONS in Mandrake. 2. Still from the OSS documentation, I must do the following step: rm /usr/src/linux/include/linux/modversions.h rm..... bla... bla... bla... And I can't find the "/usr/src/linux" directory on my hardisk. Is there someone can help me why "make" command and "usr/src/linux" directory isn't available..??? or maybe I forget something in installation procedure...?? Thanks in advance..... <-- XE -->
