DiskGenius，作为国内最有名的数据恢复与硬盘分区管理软件，其最新版本 Ver 4.4.0
新增了硬盘扇区编辑功能。如果你是一位专业的数据恢复人士，现在就不必在恢复数据时，一会用DiskGenius扫描硬盘上的分区、目录与文件，一会又打开WinHex手工修改硬盘扇区数据了。使用DiskGenius一个工具就全搞定了！既可以扫描硬盘，又可以手工修改硬盘扇区数据，而且DiskGenius的硬盘扇区编辑功能，无论在功能上，还是在使用上，同WinHex都非常相像，完全不需要重新学习。
最新版的Diskgenius Ver
4.4.0另一重大改进是对分区备份的底层代码做了大幅度的优化，极大的提高了分区备份的速度。事实上在我们的测试中，DiskGenius的备份速度远远超过其他的备份软件，唯一和DiskGenius速度相似的备份软件是易数一键还原（http://www.onekeyrestore.cn）,这也很容易理解，因为易数一键还原本来就是使用了DiskGenius的内核，这两个软件备份分区的底层代码是相同的！
configure' configures GRUB 2.00 to adapt to many kinds of systems.

VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:

Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]

[PREFIX]
By default, make install' will install all the files in /usr/local/bin', /usr/local/lib' etc. You can specify
an installation prefix other than /usr/local' using --prefix',
for instance --prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]

--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]
Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--disable-dependency-tracking speeds up one-time build
--enable-dependency-tracking do not reject slow dependency extractors
--disable-nls do not use Native Language Support
--disable-rpath do not hardcode runtime library paths
--disable-largefile omit support for large files
--enable-efiemu build and install the efiemu runtimes
(default=guessed)
--disable-werror do not use -Werror when building GRUB
--enable-mm-debug include memory manager debugging
--enable-cache-stats enable disk cache statistics collection

(default=guessed)
--enable-grub-mount build and install the grub-mount' utility
(default=guessed)
--enable-device-mapper enable Linux device-mapper support (default=guessed)
--enable-libzfs enable libzfs integration (default=guessed)
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-platform=PLATFORM
select the host platform [[guessed]]
--with-bootdir=DIR set the name of /boot directory [[guessed]]
--with-grubdir=DIR set the name of grub directory [[guessed]]
--with-gnu-ld assume the C compiler uses GNU ld default=no
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-libintl-prefix[=DIR] search for libintl in DIR/include and DIR/lib
--without-libintl-prefix don't search for libintl in includedir and libdir
--without-included-regex
don't compile regex; this is the default on systems
with recent-enough versions of the GNU C Library
(use with caution on other systems).
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
YACC The Yet Another Compiler Compiler' implementation to use.
Defaults to the first program found out of: bison -y', byacc', yacc'.
YFLAGS The list of arguments that will be passed by default to $YACC.
This script will default YFLAGS to the empty string to avoid a
default value of -d' given by some make applications.
CPP C preprocessor
CCAS assembler compiler command (defaults to CC)
CCASFLAGS assembler compiler flags (defaults to CFLAGS)
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
SYNOPSIS

-p, --prefix=DIR
set grub_prefix directory [default=/boot/grub]
-m, --memdisk=FILE

if you compile grub2 , you may get “error: ‘gets’ undeclared here yum”, to fix it, run the following command:
sed -i -e '/gets is a security/d' grub-core/gnulib/stdio.in.h
