NRC_Dev_Env_Setup_Guide_v1.0状态：已发布14 VMIVME-7700目标板内置PXE。为了使目标能够通过网络加载Linux内核并使用NFS装载其根文件系统，必须配置pxelinux引导加载器。pxelinux引导加载程序是syslinuxrpm包的一部分，作为Fedora Core 2的一部分安装在开发PC上。要启用PXE，请将配置文件pxelinux_conf从ftp站点的目录/development/host/scripts/pxelinux复制到下载目录。使用终端窗口输入以下命令：1。cp/usr/lib/syslinux/pxelinux.0$TARGET/tftpboot 2。mkdir$TARGET/tftpboot/pxelinux.cfg 3。mv$DOWNLOAD/pxelinux_conf$TARGET/tftpboot/pxelinux.cfg/pxelinux的配置文件需要根据目标IP地址的十六进制表示来命名。gethostip工具可用于为IP地址提供十六进制表示，例如：gethostip 192.168.1.10返回：C0A8010A以下部分显示使用gethostip的输出重命名配置文件：1。gethostip 192.168.1.10 2。cd$TARGET/tftpboot/pxelinux.cfg 3。mv pxelinux_conf C0A8010A开发PC设置现已完成。NRC_Dev_Env_Setup_Guide_v1.0状态：已发布15 3。VMIVME-7700目标设置本章介绍VMIC中VMIVME-770板的安装、配置、连接和使用。VMIVME-7700板是基于Intel超低电压Celeron 650 Mhz处理器的高度集成单板计算机（SBC）。目标板的硬件组件如表3-1所示：表3-1：VMIVME-7700功能特点描述处理器Intel超低电压赛扬650Mhz芯片组Intel 815E RAM内存512Mb PC100 SDRAM NVRAM 32Kb CompactFlash 128Mb PMC扩展站点1夹层卡扩展站点RS-232 2微DB9连接器前面板USB 2连接器以太网双以太网控制器（Intel 82551ER）支持10BaseT和100BaseTx接口键盘/鼠标端口连接器，提供在前面板SVGA连接器上，提供在面板上定时器4可编程时间看门狗定时器1可编程看门狗定时器PCI到VMEbus Bridge Tundra Universe II芯片组，带有VME Endian转换远程以太网引导扩展ROM BIOS支持处理器从网络服务器（PXE、BOOTP、DHCP）启动。目标的设置包括以下步骤：1。下载和安装软件和文档2。目标板3的配置和安装。目标与主机PC 4的连接。目标引导NRC_Dev_Env_Setup_Guide_v1.0状态：已发布16 3.1。文档下载VMIC提供的文档集包括以下内容：1。VMIVME-7700产品手册.pdf（产品手册）2。VMIVME-7700.pdf（概述）完整的文档集可在ftp站点的目录下找到：/development/target/VMIVME-770/docs将文件复制到host/download目录后，以下命令将文档移动到/target/docs/VMIVME-7.7 0目录：cd~/target/doc mkdir VMIVME-7.700 mv$download/*VMIVME-.700 3.2。VMIVME-7700板配置为了启用对安装在板上的CompactFlash设备的写入，开关（S9）1-4号应从UP位置（默认）更改为DOWN位置。开关（S9）的位置如图3-1所示。
NRC_Dev_Env_Setup_Guide_v1.0 Status: Released 14 The VMIVME-7700 target board comes with the PXE built-in. In order to enable the target to load the Linux kernel over network and to mount its root filesytem using NFS, the pxelinux boot loader must be configured. The pxelinux boot loader is part of syslinux rpm package that is installed on the development PC as part of Fedora Core 2. To enable PXE, copy the configuration file pxelinux_conf to your download directory from the directory /develop/host/scripts/pxelinux on the ftp site. Using a terminal window enter following commands: 1. cp /usr/lib/syslinux/pxelinux.0 $TARGET/tftpboot 2. mkdir $TARGET/tftpboot/pxelinux.cfg 3. mv $DOWNLOAD/pxelinux_conf $TARGET/tftpboot/pxelinux.cfg/ The configuration file for pxelinux needs to named according to hexadecimal representation of the target IP address. The gethostip tool can be used to provide the hexadecimal representation for an IP address, for example: gethostip 192.168.1.10 returns: C0A8010A The following section shows the use of the output from gethostip to rename the configuration file: 1. gethostip 192.168.1.10 2. cd $TARGET/tftpboot/pxelinux.cfg 3. mv pxelinux_conf C0A8010A The development PC setup is now complete.
