File systems: This contain options related to filesystem drivers, as you might guess. You'll need to ensure that the filesystem used for "/" (the root directory) is compiled into your kernel. Typically, this is ext2, but it may also be ext3, JFS, XFS, or ReiserFS. Be sure to also enable the "/proc file system support" option, as most distributions require it. Typically, you should also enable "/dev/pts file system support for Unix98 PTYs," unless you're planning to use "/dev file system support," in which case you should leave the "/dev/pts" option disabled.

Console drivers: Typically, most people will enable "VGA text console" (normally required on x86 systems) and optionally "Video mode selection support." It's also possible to use "Frame-buffer support," which will cause your text console to be rendered on a graphics rather than a text screen. Some of these drivers can negatively interact with X, so it's best to stick with the VGA text console, at least in the beginning.
