linyin, First of all, you are running an old version, "OpenBSD 4.2" --The current version of OpenBSD is 4.3. >From your previous post with the subject of "Newbie some problem with OpenBSD," it is obvious you are just starting to learn OpenBSD. All users are strongly encouraged to run the GENERIC (or GENERIC.MP) kernel. The GENERIC kernel should be sufficient for most all systems and situations. There are only three situations where anyone should run a custom kernel: 1.) Development/Testing 2.) Resolving Conflicts 3.) Needed Functionality In situation #1, people are developing or testing new kernel level functionality and obviously have a verifiable need to run a custom kernel on their dev/test machine. In situation #2, using a custom kernel is required to get past a conflict caused by your hardware. There are situations where some hardware misrepresents itself, or is misidentified, or conflicts with other drivers/hardware. The only way to get past the conflict and/or misidentification problem is to disable and/or enable support for the actual hardware you have. Even when you have conflicts, often you do not need to build a custom kernel since you can reconfigure the GENERIC kernel through the config(8) utility. (see `man config`) In situation #3, you have a specific need for functionality not included in the GENERIC kernel. A good example is if you have a real need to support the NTFS file system, you would need to build a custom kernel with the NTFS support enabled. --The main reason why many seldom used features are not enabled by default in the GENERIC kernel is to keep the kernel small. Unless you have a verifiable need to run a modified kernel, you should always be running GENERIC (or GENERIC.MP). If you insist on messing around with the kernel, no one on these will help you, and mainly because they cannot help you without knowing exactly what tweaks and modifications you're actually running. Even if you are an absolute expert with computer systems and operating system design, running the default GENERIC (or GENERIC.MP) kernel whenever possible is always the very best way to manage your OpenBSD system properly.
