UEFI/GPT相关的知识

维基百科:Unified Extensible Firmware Interface  统一可扩展固件接口

无忧论坛的帖子:http://bbs.wuyou.com/forum.php?mod=viewthread&tid=299643&extra=page%3D1 比较靠近实际,易操作

UEFI支持x64和x86,但是x86的UEFI还是很少见的,而且一般UEFI启动x86的时候就直接转到传统bios兼容模式了。

GPT是UEFI下面的一个标准,但是GPT是可以单独使用的。

UEFI与传统BIOS最大的不同可能就是,UEFI是从文件启动的,再也不用写入什么MBR了。这对U盘启动来说特别方便。

windows 8

原来windows 8 中文版不能使用组策略和被远程桌面连接,无法用这个版本了。用了下windows 8,能感觉到微软是想要windows 8 往移动互联网方向发展的,有一些手机系统的特征。

联想OEM出厂分区

发现很简单,就是windowsRE分区+ESP分区(+MSR分区+)+OS分区+…+恢复镜像分区。

WindowsRE分区用来系统恢复,U盘winPE可以替代;支持UEFI的操作系统会将引导文件写入ESP分区,所以ESP删除也没问题;MSR目前根本没用;恢复镜像带一大堆垃圾软件,不如不要,重装来得清爽。

推荐的UEFI/GTP驱动器分区

关于windowsRE还是微软官方的资料好用,参见 部署 Windows RE 以及链接出去的N多页面。还有几个命令行工具的使用方法diskpart、dism、reagentc。

还有几个问题:

ESP分区除了存储启动程序等efi应用,还是可以存放efi驱动,没见过这种驱动?

UEFI启动的顺序由ROM里的变量控制,这些变量可以通过UEFI bios进行修改(联想貌似没有设置,也没提供uefi shell。。。),这些变量的内容具体到文件还是驱动器?

一直想给电脑多装几个系统,当初买来这500GB硬盘分区的时候,还特意留了一些空白空间为以后装系统用。

以前是先装xp,再装win7,双系统启动菜单自动生成(现在发现可以通过boot.ini实现,但是不知道不在bcd里面添加启动项—旧OS加载器—可以不)。最开始的时候还手工折腾过bcdedit命令行,略有成就感,后来用了VistaBootPro,现在有更好用的easybcd。

又后来加了一个ubuntu,通过在boot.ini中添加一项grub4dos的引导文件来引导ubuntu的grub2,只是这导致了windows激活失败(db……)。原因是grub4dos覆盖了激活软件释放的grldr,这个同名的激活用的文件是用来修改系统启动时从bios复制来的特殊的值,起到在bios和os之间摆一道的作用。为了搞定这个问题,找啊找,找到某人做的SLIC 2.1的BIOS,拿来直接用了,双击运行,也不需要什么研究了。这个方法俗称硬刷。

刚搞三系统的时候ubuntu还是gnome2,出了那新版界面后一直有点排斥。就这样到现在了。

最近又想折腾了,所以又学习一次,再深入一点点。总算不上系统学习……

Vorrazano, an Italian about whom little is known, sailed into New York Harbour in 1524 and named it Angouleme. He described it as ‘a very agreeable situation located with two small hills in the midst of which flowed a great river. Though Vorrazano is by no means considered to be great explorer, his name will probably remain immortal, for on November 21st, 1964, the longest suspension bridge was named after him.

The Vorrazano Bridge, which was designed by Othmar Amman, joins Brooklyn to Staten Island. It has a span of 4200 feet. The bridge is so long that the shape of the earth had to be taken into account by its designer. Two towers support four huge cables. The towers are built on immense underwater platforms made of steel and concrete. The platforms extend to a depth of over 100 feet. These alone took sixteen months to build. Above the surface of the water, the towers rise to a height of nearly 700 feet. They support the cables from which the bridge has been suspended. Each of the four cables contains 26108 lengths of wire. It has been estimated that if the bridge were packed with cars, it would still only be carrying a third of its capacity. However, size and strength are not the only important things about this bridge. Despite its immensity, it is both simple and elegant, fulfilling its designer’s dream to create ‘a enormous object drawn as faintly as possible’.

There was a time when the owners of shops and businesses in Chicago had to pay large sums of money to gangsters in return for ‘protection’. If the money was not paid promptly, the gangsters would quickly put a man out of business by destroying his shop. Obtaining protection money is not a modern crime. As long ago as the fourteenth century, Sir Joxx Hawkwood, an Englishman, make the remarkable discovery that people would rather pay large sums of money to gangsters than have their life work destroyed.

Six hundred years ago, Sir xxx Hawkwood arrived in Italy with a band of soldiers and settled near Florence. He soon made a name for himself and came to be known to the Italians as Giovanni Acuto. Whenever the Italian city-states were at war with each other,  Hwakwood used to hire his soldiers to princes who were willing to pay the high price he demanded. In times of peace, when business was bad, Hawkwood and his men would march into a city-state and, after burning down a few farms, would offer to go away if protection money was paid to them. He made larges sums of money in this way. In spite of this, the Italians regarded him as a sort of hero. When he died at the age of eighty, the Florentines gave him a state funeral and had a picture painted which was dedicated to the memory of ‘the most valiant soldier and the most notable leader, Singor Giovanni Hawkodue.’

Step into spring

It’s that time of year

Nature is bursting into life

Time for you to buy something new

Shake off those winter blues

Add some colour to your wordrobe

Put some fresh flavour in your cooking
