Hi there,

Im trying to optimize the kernel on my server. The first thing I would like to do is disable everything I don't need in the kernel using make menuconfig. The kernel version I am using is 2.6.16.16 from kernel.org. Is there any way to get a list of drivers the kernel is using to disable everything its not using. The modules has been easy, all I have to do is lsmod. Some stuff is obvious like disabling sound and parallel port. But I still see almost everything turned on in the menus. For example the server I am using has a SATA card. To get it to work I ended up building in ever SATA and most SCSI drivers into the kernel. The server is located at 1&1 so I can't go take a look at it to see what hardware it has. I have also tried googling up the hardware list I got from lspci with no luck. Also is there a guide somewhere on the internet that tells you what most of those kernel options do. As well as which one are required for the kernel to actually work. The build-in help isnt very useful.

Thank you,

No easy way than knowing what you have and need. And sata requires the basics of scsi to work as does USB and Firewire. They use the scsi structure to interface with the kernel. Beats writing a whole new kernel interface when something as wonderful as scsi interface exist.
