Make sure you've run "make config", saved a configuration, and then run "make dep". If this doesn't help, talk to the driver's maintainer (look in /path/to/the/kernel/source/tree/MAINTAINERS). Regarding the inclusion of a (maybe) useless driver: in the interest of keeping up code reuse, sometimes the kernel will compile in drivers that aren't needed -- call it an added bonus. 8-) >-the other problem is in boot sequence, i prapre the kernel image for >the rootdisk(it work with a Slackware bootdisk) like this: >> rdev bzImage /dev/fd0 >> rdev -r bzImage 49152 (49152 = ask disk, and read from 0) >> rdev -R bzImage 0 (to make the root RW and allow to login) >> dd if=bzImage of=/dev/fd0 bs=1k > >howener then i insert root disk, 10 second oafter, i see this >message: >>wrong magic (I could be talking out my butt here and for the rest of my reply; I'd appreciate it if filesystem gurus would back me up... or not) In every boot sector is written a "magic number". This is unique for each filesystem type, and is used upon initial mount for partition type identification; apparently the wrong magic number was written to the disk.

If I'm wrong (and I frequently am; I'm merely a newbie with ambition), I'm sorry (read: don't flame me). Colin Bayer "Nothing's tweaked to the limit until it's broken.
