325 The kernel memory allocator divides physically contiguous memory
326 blocks into "zones", where each zone is a power of two number of
327 pages. This option selects the largest power of two that the kernel
328 keeps in the memory allocator. If you need to allocate very large
329 blocks of physically contiguous memory, then you may need to
330 increase this value.
331
332 This config option is actually maximum order plus one. For example,
333 a value of 13 means that the largest free memory block is 2^12 pages.

405 Even if you say Y here, the currently visible virtual console
406 (/dev/tty0) will still be used as the system console by default, but
407 you can alter that using a kernel command line option such as
408 "console=ttyS1". (Try "man bootparam" or see the documentation of
409 your boot loader (silo) about how to pass options to the kernel at
410 boot time.)
411
412 If you don't have a graphics card installed and you say Y here, the
