I reccomend to read the Battery-Powered mini HOWTO and the chapter about kernel recompilation on the RedHat manual before proceeding to recompile the kernel for your notebook. While making xconfig (or menuconfig or whatever you want to use) pay attention to the following:
Advanced Power Management BIOS support: Yes Ignore USER SUSPEND: No Enable PM at boot time: Yes Make CPU Idle calls when idle: Yes Enable console blanking using APM: Yes Power off on shutdown: Yes
# # Sound # CONFIG_SOUND=y CONFIG_AUDIO=y CONFIG_MIDI=y CONFIG_YM3812=m # CONFIG_PAS is not set CONFIG_SB=y CONFIG_ADLIB=m # CONFIG_GUS is not set # CONFIG_PSS is not set CONFIG_MPU401=m # CONFIG_UART6850 is not set CONFIG_UART401=y # CONFIG_MSS is not set # CONFIG_SSCAPE is not set # CONFIG_TRIX is not set # CONFIG_MAD16 is not set # CONFIG_CS4232 is not set # CONFIG_MAUI is not set SBC_BASE=220 SBC_IRQ=5 SBC_DMA=1 SB_DMA2=1 SB_MPU_BASE=330 SB_MPU_IRQ=10 DSP_BUFFSIZE=65536 # CONFIG_LOWLEVEL_SOUND is not set
The OPL3 chip is not detected. Nevertheless Kmid, a program belonging to the KDE desktop enviroment, can play many MIDI files without problems. The drivers OSS/Free provided by http://www.4front-tech.com are supposed to improve the performance, if compared to the standard Linux drivers.
