Write a default PXE configuration containing entries for the firmware to upgrade to /tftpboot/pxelinux.cfg/default, such as the following
将包含要更新的固件的内容的默认PXE配置写入 /tftpboot/pxelinux.cfg/default，就像下面这样
Now ensure your PXE boot configuration file can send the correct image by changing the appropriate comment to set the default to BMC in the /tftpboot/pxelinux.cfg/default file previously created.
现在修改适当的注释，在前面创建的 /tftpboot/pxelinux.cfg/default文件中设置BMC 为默认项，确保PXE启动配置文件能发送正确的镜像。
Specifically, PXE-based network booting is used.
具体地说，是使用了基于PXE的网络引导。
For this step, each node must be booted using the PXE network boot option in the BIOS.
对于这个步骤，每个节点都必须在BIOS中使用PXE网络启动选项来启动。
When a PXE client boots, it must do two things.

PXE is geared toward automated, unattended management of user PCs and workstations.
PXE适合用户PC机和工作站自动的、无人值守的管理。
PXE defines the way in which a PC should load its operating system from a remote boot server.
PXE定义了从远程引导服务器给PC机装操作系统的方法。
Using the downloadable diag facility b57udiag -cmd, choose the device and then disable PXE boot.

CONCLUSION: PXE is a multisystem disorder affecting the dermatologic, ocular, and cardiovascular systems.
结论：PXE是一个累及多系统的疾病，它影响着皮肤、眼和心血管系统。
As an example, consider a client computer getting the address 192.168.0.2 from the server during PXE boot.
例如，假设一台客户计算机在PXE启动期间从服务器得到地址192.168.0.2。
All PXE request packets have a DHCP option value that indicates the time (in seconds) since the most recent boot.
所有的PXE请求数据包具有一个dhcp选项值，该值指示最近启动以来的时间(以秒为单位)。
On another computer (such as the one you have set up for PXE booting), mount the floppy disk containing the BIOS update.
在另一台计算机上（例如设置了PXE启动的计算机），装入包含BIOS更新的软盘。
This enables a PXE server to know (at boot time) the exact architecture of the client from the first network boot packet.
这使PXE服务器能够知道(在启动时)从第一个网络引导数据包的客户端的确切的体系结构。
At a high level, you power on the computer, it PXE boots to flash the BMC firmware, and it leaves the computer running in the DOS image.
从高层次来看，在计算机加电时，计算机通过PXE启动来刷新BMC固件，然后让计算机在dos镜像中运行。
Once you are satisfied with your modified BIOS update image, you can create a PXE boot image from the floppy disk with the following command.
对修改后的BIOS更新镜像满意之后，就可以用以下命令用软盘创建PXE启动镜像。
PXE most commonly involves booting a computer from firmware i. e., a read-only memory or programmable ROM chip rather than from magnetic media.
最常见的PXE是从固件、即只读式存储器或可编程ROM芯片，而不是从磁介质引导计算机。
The virtualization support will include alternative boot sources, ISO mounts, PXE, building your own images, and cloning images from other machines.
虚拟化支持包括可选择的启动源、ISO挂载、PXE、构建自己的镜像以及从其他机器克隆镜像等。
Unfortunately, PXE calls for some options that may not work on all DHCP servers, so most software that supports PXE also includes a proxy DHCP service.
不幸的是，PXE要求的某些选择不是在所有的DHCP服务器上都行得通，因此多数支持PXE的软件还包含一个代理DHCP服务。
Of course, in order for PXE to work the server needs OS configuration, and the client side needs a code module that runs PXE for the given LAN card (NIC).
当然，为了使PXE工作服务器需要配置OS，并且客户端需要使用特定的LAN网卡(NIC)的代码模块来运行PXE。
Clients without a CD-ROM drive but with a Linux-supported bootable network card, for example, can boot remotely from a Knoppix-running server by means of PXE.
例如，不带CD - ROM驱动器，但是带有支持Linux的可引导网卡的客户机可以通过PXE从正在运行Knoppix的服务器进行远程引导。
When all updates are complete, return the default PXE boot configuration to boot from local disk to avoid any accidents if a computer were to make a PXE request.
更新完成后，把默认PXE启动配置改为从本地磁盘启动，防止计算机再次发出PXE请求时发生意外。
Pathologic examination of skin biopsy confirmed the diagnosis of PXE, showing calcium deposition and fragmented, clumped elastic fibers in the deep reticular dermis.
皮肤切片病理检查证实了PXE的诊断，显示有网状真皮层深层的钙沉积和成碎片的成丛的弹性纤维。
Pathologic examination of skin biopsy confirmed the diagnosis of PXE, showing calcium deposition and fragmented, clumped elastic fibers in the deep reticular dermis.
皮肤切片病理检查证实了PXE的诊断，显示有网状真皮层深层的钙沉积和成碎片的成丛的弹性纤维。
