I found this works with the default 2.4.7 kernel from teh install, but after recompiling my kernel it does not work, even though I have the correct drivers. I also had problems with 2.4.14 kernel as well. Is there a config option that I am missing? CONFIG_PARPORT=m CONFIG_PARPORT_PC=m CONFIG_PARPORT_PC_CML1=m # CONFIG_PARPORT_SERIAL is not set CONFIG_PARPORT_PC_FIFO=y CONFIG_PARPORT_PC_SUPERIO=y # CONFIG_PARPORT_AMIGA is not set # CONFIG_PARPORT_MFC3 is not set # CONFIG_PARPORT_ATARI is not set # CONFIG_PARPORT_GSC is not set # CONFIG_PARPORT_SUNBPP is not set CONFIG_PARPORT_OTHER=y CONFIG_PARPORT_1284=y CONFIG_VIDEO_PROC_FS=y CONFIG_I2C_PARPORT=m # CONFIG_VIDEO_PMS is not set # CONFIG_VIDEO_BWQCAM is not set # CONFIG_VIDEO_CQCAM is not set # CONFIG_VIDEO_W9966 is not set CONFIG_VIDEO_CPIA=m CONFIG_VIDEO_CPIA_PP=m
Okay after more research it turns out that it is not a redhat issue. it is an issue that arrose in 2.4.14 kernel as the driver works in both 2.4.7 RH default, my custom build 2.4.7 RH source and also 2.4.13 tree.
