 ==== Example of preseed file ====
+I've removed pretty much all comments. What's below is my preseed file.
+Please, see example preseed files/documentation for explanation, hints
+and, actually, more.

 ### Partitioning
-## Partitioning example

-# /dev/sda, and not e.g. /dev/discs/disc0/disc).
-# For example, to use the first SCSI/SATA hard disk:
-#d-i partman-auto/disk string /dev/sda
-# In addition, you'll need to specify the method to use.
-# The presently available methods are:
-# - regular: use the usual partition types for your architecture
-# - lvm:     use LVM to partition the disk
-# - crypto:  use LVM within an encrypted partition
 d-i partman-auto/method string lvm

-# - multi:  separate /home, /usr, /var, and /tmp partitions

+Turning off Frame Buffer(''fb'') in installer is usefull when eg. ''curses'' is used instead of ''SDL'' to display VGA output.
+However, turning Frame Buffer off means graphics in installer will go wonky from time to time even when running in SDL window.
