一.准备前提
1.联想G510AT
用winpe进入笔记本电脑，找到一个分区，删除即可
2.使用U盘安装
2.1.准备一个8G 的U盘，格式化ntfs。
2.2.在window下，下载UltraISO，一般最新版即可，用户名：王涛；注册码：7C81-1689-4046-626F
2.3.下载centos，一般下载dvd版本，即可，
2.4.使用UltralSO装载centos，启动-》写入磁盘映像，即可
3.U盘启动
启动电脑，进入bios，设置Legacy support，first；
待电脑重启，进入Install Centos 后，
按tab建，将命令修改为：>vmlinuz initrd=initrd.img linux dd quiet
根据提示 ctrl+ X 重启，后可查看u盘系统。abd4 或者其他，修改命令：>vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sdc4 quiet
4.进入系统安装界面。
软件安装可以选择，gnone，磁盘设置swap 为内存1-2倍
其他使用默认即可。安装完毕即可使用
二.安装网卡
1.先使用网线连接，确定网卡类型Broadcom：lspci | grep Broadcom
确认为：BCM43142

Source RPMs for Broadcom drivers
Please note: The current Broadcom closed-source Linux drivers when built according to the instructions provided here have provided functional wireless capability to some users, but have failed for other users.Broadcom Corp. provides closed-source IEEE 802.11a/b/g/n Linux drivers for use with Broadcom's BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM4331, BCM4352, BCM4360, BCM43142, BCM43224, BCM43225, BCM43227 and BCM43228 wireless chipsets. We (ELRepo) cannot create and redistribute binary RPMS for these drivers due to the Broadcom licensing restrictions (i.e., liability issues). However, we do make available no-source SRPMS (.nosrc.rpm) which contain the framework required to build the binaries, but lack the proprietary code and are not subject to Broadcom's licensing restrictions.These no-source SRPMS can be used by the end user to build kABI-compatible binary drivers for local use. These kABI-compatible binaries should be usable after future kernel updates, so there is no need to recompile them for each new kernel. Please note that the nosrc.rpm package does not build kmod-wl for kernel-xen and kmod-wl cannot be built on a system running kernel-xen.To build a kmod-wl binary, you will need to (1) configure a build tree, (2) download the wl-kmod*nosrc.rpm for your EL release, (3) download the closed-source tarball from Broadcom for your architecture (i.e., 32-bit vs 64-bit) into the build tree and (4) initiate the kmod-wl build. For convenience, the kernel development package for the running kernel will be used in the build process, as opposed to our normal policy of building against an older kernel development package.The kmod-wl package can be built on any system running the same EL release/architecture as the target system. If you are building on the target system and lack network connectivity, then the downloads can be made onto a USB flash drive and copied onto your system.Below are the detailed instructions on how to build the binary packages from our no-source SRPM. If you are already familiar with using rpmbuild to build packages, then this process should only take you 5-10 minutes to complete.Kmod-wl Usability Across EL Point Releases (or ″Why doesn′t my wireless work after the last point release update?″):If you are only interested in building kmod-wl for the latest kernel, then you do not really need to read this section, but it would not hurt to understand the underlying issues.The EL6 and EL7 kmod-wl binaries are typically only functional within a range of EL point releases (e.g., 6.8-6.9, 7.4) due to changes in the wireless stack-related kernel API of the EL 6 and EL 7 kernels. RHEL backports (external link) components of recent kernels so that more modern kernel features and security fixes are available to the user. These backports become most notable when a new point release becomes available.Our kmods continue to work after updating the kernel as long as the Kernel Application Binary Interface (kABI) remains unchanged with respect to our packages. EL point releases sometime break this compatibility. For the kmod-wl package, we make changes to the wl-kmod srpm to accommodate these changes. One down side is that the newly built kmod-wl only works within the newest RHEL point release after a wl-kmod srpm update. To maintain backward compatibility of the wl-kmod srpm, we craft it to build slightly different kmod-wl packages depending on the point release kernel used to build it.If your interest is to only use the newest kernel, then you can just boot to the newest kernel and follow the instructions (below) to build a usable kmod-wl. However, if you need to continue using an older kernel, then you can use the updated wl-kmod srpm to build a kmod-wl package that works with the older kernel.How to do that: If you build kmod-wl from the updated srpm after booting the latest kernel, then you can save that kmod-wl for use with the latest kernel. Likewise, you can build kmod-wl from the updated srpm after booting an older point release kernel and then save that kmod-wl for use with the older point release kernel. (For users familiar with using rpmbuild, you can also use the " --define 'kversion TARGET-KVERSION ' " option to avoid booting different kernels.) Unfortunately, you can only have one of those kmod-wl packages installed at a time, so save both kmod-wl packages, but only install one of them. Note that they have exactly the same version (i.e., their rpm names are identical), so save them in separate folders.For example, you can build kmod-wl under an EL 7.2 kernel and use it with EL 7.2 kernels, but it will not function when you boot EL 7.1 or EL 7.3 kernels. Likewise, you can build kmod-wl under an EL 7.3 kernel and use it with EL 7.3 kernels, but it will not function when you boot EL 7.1 or EL 7.2 kernels.If you need a kmod-wl package that works within one of the following ranges, then boot a kernel in that range and build/install kmod-wl as described below.Supported EL 6 Point Release Ranges: (1) 6.3 - 6.4, (2) 6.5 - 6.6, (3) 6.7, (4) 6.8 - 6.9Supported EL 7 Point Release Ranges: (1) 7.0, (2) 7.1, (3) 7.2, (4) 7.3, (5) 7.4Build and install kmod-wl for EL6/7Please note:If your current kmod-wl package works with an older kernel and wireless networking is your only Internet access method,then boot the older kernel and download the new srpm and Broadcom source before proceeding.1) Install needed tools/packages:1a) EL6:# yum groupinstall 'Development Tools'# yum install redhat-lsb kernel-abi-whitelists# yum install kernel-devel-$(uname -r)EL 6.4 - 6.6 Note: Due to a bug in redhat-rpm-config-9.0.3-42.el6, a modification is required to fix thekabi-whitelist target in /usr/lib/rpm/redhat/find-requires.ksyms before you build kmod-wl.Please run as root (as a single copy/paste):[[ $(rpm -q redhat-rpm-config|grep 9.0.3-42|wc -l) -gt 0 ]] && sed -i \'s@/lib/modules/kabi/kabi_whitelist@/lib/modules/kabi-current/kabi_whitelist@g' \/usr/lib/rpm/redhat/find-requires.ksymsThe above modification is not needed for EL 6.7 or later.1b) EL7:# yum group install 'Development Tools'# yum install redhat-lsb kernel-abi-whitelists# yum install kernel-devel-$(uname -r)EL 7.0 Note: Due to a bug in redhat-rpm-config-9.1.0-63.el7, a modification is required to fix thekabi-whitelist target in /usr/lib/rpm/redhat/find-requires.ksyms before you build kmod-wl.Please run as root (as a single copy/paste):[[ $(rpm -q redhat-rpm-config|grep 9.1.0-63|wc -l) -gt 0 ]] && sed -i \'s@/lib/modules/kabi/kabi_whitelist@/lib/modules/kabi-rhel70/kabi_whitelist@g' \/usr/lib/rpm/redhat/find-requires.ksymsThe above modification is not needed for EL 7.1 or later.2) As a regular user (not as root), configure a build tree and minimal .rpmmacros:$ mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}$ echo -e "%_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s -r|cut -d"." -f1).local" >> ~/.rpmmacros3) Download wl-kmod*nosrc.rpmFor EL6: http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-6_30_223_271-3.el6.elrepo.nosrc.rpm (external link)For EL7: http://elrepo.org/linux/elrepo/el7/SRPMS/wl-kmod-6_30_223_271-4.el7.elrepo.nosrc.rpm (external link)4) Download the Broadcom driver matching your architecture (i.e., 32-bit vs 64-bit):from: http://www.broadcom.com/support/802.11 (external link) (scroll down to "Linux® STA 32-bit (or 64-bit) drivers")to: ~/rpmbuild/SOURCES/5) Build kmod-wl as a regular user (not as root):$ rpmbuild --rebuild --define 'packager <your-name>' /<path-to-nosrc.rpm>/wl-kmod*nosrc.rpm...Wrote: /home/<user>/rpmbuild/RPMS/x86_64/kmod-wl-<version>.x86_64.rpm...+ exit 06) If ndiswrapper is installed and is no longer needed, then remove it:# yum remove \*ndiswrapper\*7) Install kmod-wl:Note for EL7: Recent hardware is often shipped with an Unified Extensible Firmware Interface (UEFI) in which Secure Boot is enabled.

三.切换命令行与图型化切换
命令行：
systemctl set-default multi-user.tartget
图形化：
systemctl set-default graphical.target
reboot重启校验即可。
四.显卡驱动
amd 安装，目前由于系统使用的是centos7。4 ，故，暂时无法安装XServer。Xserver 版本过高。。
