Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.
For now, there is not much documentation yet. Please look at the GRUB
Wiki <http://grub.enbug.org> for testing procedures.
More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.
Please look at the GRUB Wiki <http://grub.enbug.org> for testing

This means the BSD @samp{a} partition of the second hard disk. If you
need to specify which @sc{pc} slice number should be used, use something
like this: @samp{(hd1,1,a)}. If the @sc{pc} slice number is omitted,
GRUB searches for the first @sc{pc} slice which has a BSD @samp{a}
partition.
This means the BSD @samp{a} partition on first @sc{pc} slice number
of the second hard disk.
Of course, to actually access the disks or partitions with GRUB, you
need to use the device specification in a command, like @samp{set
root=(fd0)} or @samp{parttool (hd0,3) hidden-}. To help you find out
root=(fd0)} or @samp{parttool (hd0,msdos3) hidden-}. To help you find out
which number specifies a partition you want, the GRUB command-line
(@pxref{Command-line interface}) options have argument
completion. This means that, for example, you only need to type
