Hello. I wonder if there is a user function which allows root to access the ISA bus address 0x08fcf8. Is there a way so that I don't need to write kernel device driver and compile the kernel again because somehow reinstallation of the kernel doesn't work. I heard about the function mmap(). I just want to read/write to the address 0x08fcf8. Will mmap() work? How? Please help. Thanks. ~Ming Chak Lee~
