ipxe编译（分别编译基于bios+ipxe、uefi+ipxe的方式）

额外介绍 ipxe.org 已经编译好的固件 http://boot.ipxe.org/

编译环境准备（Rock Linux 9默认最小化安装）

# 安装编译所需环境
    dnf install git
    dnf install gcc make perl xz-devel mtools mkisofs syslinux
    # dnf install gcc make perl xz-devel mtools xorriso syslinux

拉取ipxe的源码

# ipxe项目源码地址 https://github.com/ipxe/ipxe.git
    cd /root/
    git clone https://github.com/ipxe/ipxe.git

让编译的ipxe支持自定义分辨率 和 背景图片 + ping命令支持

1、启用ipxe的console命令，让ipxe支持调整分辨率 以及 支持自定义背景图片
    # 参考链接 https://ipxe.org/buildcfg/console_cmd    https://ipxe.org/cmd/console
    # 1、需要修改 ipxe/src/config/general.h 文件内容；取消 #define IMAGE_PNG 和 #define CONSOLE_CM 前面的//注释
    # 2、需要修改 ipxe/src/config/console.h 文件内容；取消 #define CONSOLE_FRAMEBUFFER 前面的//注释

    cd /root/ipxe/src
    sed -i 's/\/\/#define\ IMAGE_PNG/#define\ IMAGE_PNG/' config/general.h
    sed -i 's/\/\/#define\ CONSOLE_CMD/#define\ CONSOLE_CMD/' config/general.h
    sed -i 's/\/\/#define\tCONSOLE_FRAMEBUFFER/#define\tCONSOLE_FRAMEBUFFER/' config/console.h

2、启用ipxe的ping命令
    # ping cmd support
    cd /root/ipxe/src
    sed -i 's/\/\/#define\ PING_CMD/#define\ PING_CMD/' config/general.h

编译适用于bios+ipxe方式的undionly.kpxe

# 进入源码目录
    cd /root/ipxe/src/

# 设置自定义菜单
    cat bootmenu.ipxe
#!ipxe

# 编译
    make bin/undionly.kpxe EMBED=bootmenu.ipxe
    cp bin/undionly.kpxe /var/lib/tftpboot/

    # 或者这样一步编译  makebin/undionly.kpxe bin-x86_64-efi/ipxe.efi EMBED=bootmenu.ipxe

编译适用于uefi+ipxe方式的ipxe.efi

# 进入源码目录
    cd /root/ipxe/src/

# 设置自定义菜单

# 编译
    make bin-x86_64-efi/ipxe.efi EMBED=bootmenu.ipxe
    cp bin-x86_64-efi/ipxe.efi /var/lib/tftpboot/

附一、为ipxe启用附加支持

# 进入ipxe源码目录
cd /root/ipxe/src

# Console Background and Console Custom resolution support
sed -i 's/\/\/#define\ IMAGE_PNG/#define\ IMAGE_PNG/' config/general.h
sed -i 's/\/\/#define\ CONSOLE_CMD/#define\ CONSOLE_CMD/' config/general.h
sed -i 's/\/\/#define\tCONSOLE_FRAMEBUFFER/#define\tCONSOLE_FRAMEBUFFER/' config/console.h

# NFS protocol support
sed -i 's/#undef\tDOWNLOAD_PROTO_NFS/#define\tDOWNLOAD_PROTO_NFS/' config/general.h

# ping cmd support
sed -i 's/\/\/#define\ PING_CMD/#define\ PING_CMD/' config/general.h

# poweroff and reboot cmd support
sed -i 's/\/\/#define\ REBOOT_CMD/#define\ REBOOT_CMD/' config/general.h
sed -i 's/\/\/#define\ POWEROFF/#define\ POWEROFF/' config/general.h

# params cmd support （开启他，可以传参 platform ${builtin/platform} 的 pcbios 和 efi 参数值）
sed -i 's/\/\/#define\ PARAM_CMD/#define\ PARAM_CMD/' config/general.h

附加bug,新版ipxe部分在安装windows时，ipxe下载boot.wim过程极度缓慢
