	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	If your system has UEFI support and you wish to boot LFS with UEFI, you should skip the instructions in this page but still learn the syntax of <filename>grub.cfg</filename> and the method to specify a partition in the file from this page, and configure GRUB with UEFI support using the instructions provided in <ulink url="&blfs-book;postlfs/grub-setup.html">the BLFS page</ulink>.

	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	GRUB uses its own naming structure for drives and partitions in the form of <emphasis>(hdn,m)</emphasis>, where <emphasis>n</emphasis> is the hard drive number and <emphasis>m</emphasis> is the partition number. The hard drive numbers start from zero, but the partition numbers start from one for normal partitions (from five for extended partitions). Note that this is different from earlier versions where both numbers started from zero. For example, partition <filename class="partition">sda1</filename> is <emphasis>(hd0,1)</emphasis> to GRUB and <filename class="partition">sdb3</filename> is <emphasis>(hd1,3)</emphasis>. In contrast to Linux, GRUB does not consider CD-ROM drives to be hard drives. For example, if using a CD on <filename class="partition">hdb</filename> and a second hard drive on <filename class="partition">hdc</filename>, that second hard drive would still be <emphasis>(hd1)</emphasis>.	GRUB 使用一种独特的命名结构，为驱动器和分区命名。分区名的形式为 <emphasis>(hdn,m)</emphasis>，这里 <emphasis>n</emphasis> 是硬盘驱动器编号，<emphasis>m</emphasis> 是分区编号。硬盘驱动器编号从 0 开始，但分区号对于主分区来说从 1 开始，而对于扩展分区来说从 5 开始。例如，分区 <filename class="partition">sda1</filename> 在 GRUB 中的名字是 <emphasis>(hd0, 1)</emphasis>，而 <filename class="partition">sda3</filename> 的名字是 <emphasis>(hd1, 3)</emphasis>。和 Linux 不同，GRUB 不认为 CD-ROM 驱动器属于硬盘驱动器。例如，如果在 <filename class="partition">hdb</filename> 上有一个 CD-ROM 驱动器，而 <filename class="partition">hdc</filename> 上有第二个硬盘驱动器，则第二个硬盘驱动器仍然名为 <emphasis>hd1</emphasis>。
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	The location of the boot partition is a choice of the user that affects the configuration. One recommendation is to have a separate small (suggested size is 200 MB) partition just for boot information. That way each build, whether LFS or some commercial distro, can access the same boot files and access can be made from any booted system. If you choose to do this, you will need to mount the separate partition, move all files in the current <filename class="directory">/boot</filename> directory (e.g. the Linux kernel you just built in the previous section) to the new partition. You will then need to unmount the partition and remount it as <filename class="directory">/boot</filename>. If you do this, be sure to update <filename>/etc/fstab</filename>.	引导分区的位置由负责进行配置的用户自己决定，作者推荐创建一个小的 (建议大小为 200 MB) 分区，专门存放引导信息。这样，不同的 Linux 系统 (无论是 LFS 还是商业发行版) 在启动时和启动后都能访问相同的引导文件。如果您选择这样做，您需要挂载这个单独的分区，将 <filename class="directory">/boot</filename> 中已有的文件 (例如上一节中构建的内核) 移动到新的分区中。之后，解除该分区的挂载，并将它挂载为 <filename class="directory">/boot</filename>。另外，还要注意更新 <filename>/etc/fstab</filename>。
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	Leaving <filename class="directory">/boot</filename> on the current LFS partition will also work, but configuration for multiple systems is more difficult.	直接使用 LFS 分区也是可以的，但这样在配置多系统启动时比较麻烦。
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	If the system has been booted using UEFI, <command>grub-install</command> will try to install files for the <emphasis>x86_64-efi</emphasis> target, but those files have not been installed in <xref linkend="chapter-building-system"/>. If this is the case, add <option>--target i386-pc</option> to the command above.	如果系统是使用 UEFI 引导的，<command>grub-install</command> 会试图为 <emphasis>x86_64-efi</emphasis> 目标安装文件，但它们并未在第 6 章中安装。如果出现了这类问题，请在以上命令中添加 <option>--target i386-pc</option> 选项。

	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	The <command>insmod</command> commands load the <application>GRUB</application> modules named <filename>part_gpt</filename> and <filename>ext2</filename>. Despite the naming, <filename>ext2</filename> actually supports <systemitem class='filesystem'>ext2</systemitem>, <systemitem class='filesystem'>ext3</systemitem>, and <systemitem class='filesystem'>ext4</systemitem> filesystems. The <command>grub-install</command> command has embedded some modules into the main <application>GRUB</application> image (installed into the MBR or the GRUB BIOS partition) to access the other modules (in <filename class='directory'>/boot/grub/i386-pc</filename>) without a chicken-or-egg issue, so with a typical configuration these two modules are already embedded and those two <command>insmod</command> commands will do nothing. But they do no harm anyway, and they may be needed with some rare configurations.
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	The <command>set gfxpayload=1024x768x32</command> command sets the resolution and color depth of the VESA framebuffer to be passed to the kernel. It's necessary for the kernel SimpleDRM driver to use the VESA framebuffer. You can use a different resolution or color depth value which better suits for your monitor.
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	The GRUB designator for a partition may change if you added or removed some disks (including removable disks like USB thumb devices). The change may cause boot failure because <filename>grub.cfg</filename> refers to some <quote>old</quote> designators. If you wish to avoid such a problem, you may use the UUID of a partition and the UUID of a filesystem instead of a GRUB designator to specify a device. Run <command>lsblk -o UUID,PARTUUID,PATH,MOUNTPOINT</command> to show the UUIDs of your filesystems (in the <literal>UUID</literal> column) and partitions (in the <literal>PARTUUID</literal> column). Then replace <literal>set root=(hdx,y)</literal> with <literal>search --set=root --fs-uuid <replaceable>&lt;UUID of the filesystem where the kernel is installed&gt;</replaceable></literal>, and replace <literal>root=/dev/sda2</literal> with <literal>root=PARTUUID=<replaceable>&lt;UUID of the partition where LFS is built&gt;</replaceable></literal>.
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	Note that the UUID of a partition is completely different from the UUID of the filesystem in this partition. Some online resources may instruct you to use <literal>root=UUID=<replaceable>&lt;filesystem UUID&gt;</replaceable></literal> instead of <literal>root=PARTUUID=<replaceable>&lt;partition UUID&gt;</replaceable></literal>, but doing so will require an initramfs, which is beyond the scope of LFS.
	Linux From Scratch 12.3/chapter10_grub — Chinese (Simplified Han script)	The name of the device node for a partition in <filename class='directory'>/dev</filename> may also change (this is less likely than a GRUB designator change). You can also replace paths to device nodes like <literal>/dev/sda1</literal> with <literal>PARTUUID=<replaceable>&lt;partition UUID&gt;</replaceable></literal>, in <filename>/etc/fstab</filename>, to avoid a potential boot failure in case the device node name has changed.
