Thiscommitment covers a range of issues, such as treating our suppliers as partners in stimulating economic growth, paying our employees fairly, and also paying tax due.As part of our commitment to greater transparency in how we run our business, Pearson is publishing detailed information on our tax on business profits around the world.Tax contributions—from individuals and businesses—are fundamental building blocks of well-functioning societies. They provide funds for governments to invest in public services including education, to create and maintain vital infrastructure, and to address inequalities.Yet tax systems and rules, both domestic and international, are often complex and difficult to understand for non-specialists. Trust in large institutions, both in government and in the private sector, has fallen, in partPearson’s mission is to help people make progress in their lives through learning. That mission informs how we invest, develop our products and services, and measure our success.because companies can do more to be transparent around tax contributions.Strengthening and maintaining public trust in the way businesses are taxed is vital. Addressing the public concern that some multinationals are not paying their fair share of tax requires both international tax reforms and better efforts to improve public understanding and awareness.This report sets out, for the first time, Pearson’s approach to tax on business profits and the contributions we make to public finances in the countries in which we operate. We have attempted to publish relevant information about our largest markets in an accessible way and to explain complex issues of accounting or tax law wherever possible. Where this report differs from Pearson’s annual report and accounts, we have sought to explain why this is.We intend this public report to provide greater insight into the way Pearson operates and we will make it a regular feature of our corporate reporting.Coram WilliamsChief Financial OfficerBe a trustedpartnerReach more learnersBuild a sustainable business1.2.3.Our strategy to deliver growth is to:Taxation principlesThis report concentrates on tax on business profits; however, our tax principles applyto all taxes, including indirect taxes or sales taxes and payroll taxes. The principles that guide us at Pearson are:1.T o comply with all relevant tax laws, regulations, and tax reporting requirements in all jurisdictions in which we operate, including claiming available tax incentives and exemptions that are available to all market participants and in accordance with generally recognized interpretationof the law.2.T o run our tax affairs in accordance with Pearson’s values, code of conduct, risk management, and governance procedures, which include regular reporting to the board, the chief financial officer, and to the audit committee on tax strategy and risks. In addition, any material changesin tax legislation, business environment, or operations will be assessed, and any resultant changes to strategy or risk will be reported as appropriate.3.T o pay tax on profits according to where value is created within the normal course of commercial activity, with transactionspriced within an appropriate arm’s-length range, i.e. cross-border transactions take place as if the parties were unconnected. Any exceptions to this are compliant with local laws and fully disclosed to the tax authorities concerned.4.T o align tax planning with business activities, for example, acquisitions, disposals, and changes in business objectives. We do not seek to avoidtax by the use of “tax havens” or by establishing arrangements that we consider to be artificial in nature or transactions that we would not fully disclose to a tax authority.5.T o achieve a more favorable tax outcome where a clear and legitimate choice exists between different options that each comply with our principles. In considering and deciding between different options, the factors we consider include commercial and reputational impact.6.T o have an open, proactive, and constructive working relationship with tax authorities. Where possible and in line with local country practice, to discuss and consult on our interpretation of the law with tax authorities as issues arise. To engage directly or indirectly with governments on proposed changes to tax legislation where appropriate.7.T o ensure our tax professionals are appropriately qualified and trained and to use external advice where appropriate.Our global tax strategyOur global tax strategy applies to all our businesses, including the UK, and this document therefore covers our obligation to publish our UK tax strategy, including governance, risk management, attitude to tax planning, and working with the UK and other tax authorities.Our approach to tax is guided by our corporate values and by our Code of Conduct. Our tax principles have been published on our corporate website since 2014. These were reviewed and refreshed this year and they guide tax strategy at Pearson.Tax incentives and arrangements We do not seek to avoid tax by establishing arrangements that we consider to be artificial in nature. We do claim available tax incentives and exemptions that are available and widely accepted as mainstream tax practice among the tax community (taxpayers, tax advisers, policymakers, and tax authorities). Tax law and regulation is complex and in each country where we operate, a common view on practice evolves over time within the relevant tax community on the interpretation and application of these rules. An important factor for us is the prevailing practice and attitude of the relevant tax authority.We have one structure in place where cross-border transactions are not pricedat arm’s length. We have set up a financing operation in Ireland which is recognizedby the tax authorities in Ireland and the UK and is subject to UK tax. These companies finance our global operations, are compliant with local laws, and are fully disclosed to the tax authorities concerned, in line with our tax principles. Tax havensThere are many different definitions of whatconstitutes a “tax haven.” Pearson does notseek to avoid tax by the use of tax havens.For this purpose, we define a tax haven asa country with a corporation tax rate of 10%or less. We assess group entities as beingin a tax haven if they are tax resident inthat country.In some instances, we have inherited somestructures with operations in tax havenswhich we unwind when we can do so at areasonable cost.In line with our principle on tax havens, weno longer have a presence in Luxembourg.As of April 2017, the group has five corporateentities based in tax haven countries, of these:– T wo were established as holdingcompanies in the Cayman Islands andBritish Virgin Islands prior to acquisitionby Pearson. Neither company is tradingand no tax benefit is derived from them,but disproportionate costs would beincurred to close them.– O ne is a small trading entity in Hungarywhich pays tax at the local rate of 10%.– O ne is an investment in Learn CapitalIIIA, incorporated in the Cayman Islands.Learn Capital is a third-party impactventure capital fund that invests ininnovative start-up companies aroundthe world. Pearson is a minority investorand does not oversee the operations oradministration of the fund. The fund is alsoregistered in the United States and allincome is reported and taxed in theUnited States; therefore, no tax benefitis obtained.– W e operate a captive insurance companydomiciled in Bermuda. This company fulfillsa commercial purpose for us, coveringthird -party risks often required by ourcustomers. We do not gain any tax benefitfrom being based in Bermuda, as all profitsare subject to UK tax. We are domiciledthere for regulatory reasons and it is arecognized global insurance center.Governance and risk managementThe board has delegated responsibility forthe integrity of financial reporting and riskmanagement to the audit committee. Thisincludes setting tax strategy and monitoringtax risk.The Tax Department reports at leastbiannually to the audit committee.Tax is part of the Pearson Finance function,reporting to our chief financial officer, whoreceives regular updates throughout the yearfrom the tax team. The chief financial officerprovides regular updates to the board ontax matters.Risk managementPearson has a structured enterprise riskmanagement framework to support theidentification and effective managementof risks across the group. As part of ourdisclosures in the annual report, we setout our principal risks and uncertainties,one of which is tax. Principal risks aredefined by Pearson as having a potentialfinancial impact greater than £50M or asignificant impact on strategy, operations,or reputation. Executive responsibilityfor tax sits with the chief financial officer.See our annual report for moreinformation /corporate/ar2016We considered tax risk as having increased slightly in 2016. Our overall assessment is that the probability of change is almost certain, reflecting the introduction of new legislation as well as the dynamic nature of tax regulation and continued public concern around tax issues.We assessed the impact on the group to be moderate. This overall assessment is informed by a longer list of tax risks which are monitored and reviewed throughout the year by the tax team. For each individual tax risk, we decide on our risk appetiteor the tolerance we have to each typeof risk. Some risks such as those relatingto legislative change we accept, while others such as compliance we seek to mitigate or avoid. Pearson manages these risks through the application of our tax principles. Management of our tax affairsAs set out in our global tax principles,in managing our tax affairs we seek to protect value for our shareholders, comply fully with legal and regulatory requirements, and align with business activities.Tax DepartmentPearson has teams of tax professionalsin the United States, the United Kingdom,and China as our largest markets by revenue,along with accountable individuals drawnfrom the finance function responsible fortax in other markets.Over the last few years, as part of our widercompany strategy to integrate and simplifyour corporate functions, we have expandedthe tax team to introduce global oversightin areas such as transfer pricing.Our tax team leads on engagementwith governments, tax authorities,and stakeholders on tax-related issues.Public policyPearson is committed to adding its voiceto the global debate on tax transparency.We contributed to, and supported, theOECD consultation on country-by-countryreporting. We also support the OECDinternational tax reform work on baseerosion and profit shifting (BEPS).We operate in a global competitiveenvironment and urge tax policymakersto implement international tax reform ina coherent, coordinated way so that thereis a level playing field and the risk of payingtax twice on the same income is minimized.Recent areas of international or national policy change affecting Pearson are as follows:Financial & tax dataWe are a global business and have trading operations in more than 70 countries around the world.Our business pays and collects a wide range of taxes, including employee taxes and sales taxes in addition to tax on business profits. This report focuseson tax on business profits.2016 was a difficult year for Pearson.We continue to face market challengesin a number of countries, and we expect these challenges to continue through 2017. During 2016, we completed acost-reduction program and postedan impairment of goodwill of £2,548M, reflecting trading pressures in our North American businesses. As a result, our statutory results showed losses for 2016 in a number of markets. This impacted tax paid in 2016 and will also impact tax due in 2017.Pearson reports its results by geography. We sell a range of educational products and services to institutions, governments, professional bodies, and individual learners. Our country operationsare split into:North AmericaCore65% of revenue. Our largest geography including all 50US states and Canada.18% of revenue. Our international business in established and mature education markets including the UK, Australia, Germany, and Italy.17% of revenue. Our education businesses in emerging and developing economies including Brazil, India, China, and South Africa. % % % 65 18 17GrowthDetailed to the right is data for 2016 for our twelve largest countries drawn from all three of our geographies, as measured using 2016 sales revenues.We then include a brief explanation of our activities in each country and, if applicable, why tax paid may appear unusual compared to profit levels. We have also provided a summary of tax paid over the most recent five years on a regional basis.For more explanation on what this data represents, please see the Appendix.* T otal revenue for each country includes intercompany sales andrecharge income, interest, and other income, all of which are excluded from the external sales reported in our Annual Report & Accounts. ** G roup adjustments include intercompany eliminations, our shareof profit from the Penguin Random House joint venture, and theimpact of disposals.A reconciliation from adjusted operating profit to statutory loss before tax is shownin the Appendix.£11M £14M £3MUnited StatesUnited Kingdom China K–12 School; HigherEducation and Professional–Assessment– Online and blended learning – Curriculum resources – Professional development– Work-based learning – Clinical assessment – TestingSchool; Higher Educationand Professional– Assessment and qualifications– Online and blended learning – Curriculum resources– Professional development– Clinical assessment – Work-based learning – D irect delivery (Pearson testing)School and Professional– C urriculum resources – E nglish language learningPearson incurred a significant restructuring cost in 2016 in the United States as well as a goodwill impairment relating to the Higher Education courseware business, resulting in a loss before tax for the year. The majority of the cash tax payments made in 2016 were at a state level.The UK is both our second-largest market by revenue and the location of our head office and central group functions. The UK also raises any external debt required by the group and this is used to fund overseas operations. Pearson also incurred a significant restructuring cost in 2016 in the UK and reported a loss before tax for the year. Tax was paid; however, some of this will be refunded in 2017.Pearson operations in China are loss-making. In February 2017, we announced our intention to either partner or sell our direct delivery business.

Under Brazilian tax legislation we are able to claim an annual tax deduction for amortization of goodwill, which will reduce our tax payments until it is utilized, which is estimated to be in 2022. In 2016, we paid tax on a foreign exchange gain, which is not expected to recur.Italy is a profitable market for Pearson.

This resulted in a loss and restructuring charge.

This is partly a result of business performance and partly a result of business disposals made in previous years, which reduced the ongoing profits of the group and resulted in tax payments on the profit on disposal.

Total revenue is therefore higher than the external sales number reported in our Annual Report and Accounts.Profit before tax: This is the profit before tax at a statutory level, which is the starting point to calculate tax on business profits. It differs from the adjusted operating profit measure which we publish in the annual report.

疏漏之处敬请反馈。

对RAID进行操作会导致数据丢失，请在操作之前务必将重要数据备份。

名称解释：Disk Group：磁盘组，这里相当于是阵列，例如配置了一个RAID5，就是一个磁盘组VD(Virtual Disk)：虚拟磁盘，虚拟磁盘可以不使用阵列的全部容量，也就是说一个磁盘组可以分为多个VDPD(Physical Disk)：物理磁盘HS：Hot Spare 热备 Mgmt：管理开机自检按Ctrl+R进raid卡配置界面【一】，创建逻辑磁盘1、按照屏幕下方的虚拟磁盘管理器提示，在VD Mgmt菜单（可以通过CTRL+P/CTRL+N切换菜单），按F2展开虚拟磁盘创建菜单2、在虚拟磁盘创建窗口，按回车键选择”Create New VD”创建新虚拟磁盘3、在RAID Level选项按回车，可以出现能够支持的RAID级别，根据具体配置的硬盘数量不同，这个位置可能出现的选项也会有所区别。

选择不同的级别，选项会有所差别。

选择好需要配置的RAID级别（我们这里以RAID5为例），按回车确认。

4、确认RAID级别以后，按Tab键，将光标移至Physical Disks列表中，上下移动至需要选择的硬盘位置，按空格键来选择（移除）列表中的硬盘，当选择的硬盘数量达到这个RAID级别所需的要求时，Basic Settings的VD Size中可以显示这个RAID的默认容量信息。

有X标志为选中的硬盘。

选择完硬盘后按Tab键，可以将光标移至VD Size栏，VD Size可以手动设定大小，也就是说可以不用将所有的容量配置在一个虚拟磁盘中。

如果这个虚拟磁盘没有使用我们所配置的RAID5阵列所有的容量，剩余的空间可以配置为另外的一个虚拟磁盘，但是配置下一个虚拟磁盘时必须返回VD Mgmt创建（可以参考第13步，会有详细说明）。

Dell BIOS设置说明

Dell BIOS设置说明目前，Dell品牌旗下的笔记本电脑分为4个系列：针对普通家庭用户的Inspiron系列、针对高端个人用户的XPS系列、商用笔记本电脑中，有面向大中型企业的Latitude系列，以及今年新推出的、针对小型企业的Vostro系列。

推出Vostro的同时，Dell也对旗下所有笔记本电脑的BIOS进行了统一更新。

下面，笔者就以Dell Vostro 1400为例，介绍新版本本BIOS的功能详解及设置方法。

一、操作方法新版BIOS是在Phoniex BIOS的基础上改进而来，相对于其他品牌本本那千篇一律上下菜单式的BIOS，Dell不但加入了完善的硬件诊断系统，在界面易用性上、说明文字的详尽程度上也是更胜一筹。

开机后，待屏幕上右上角出现提示信息时，可以按F2键直接进入BIOS；也可以按F12进入在引导设备选择菜单，从中选择“BIOS SETUP”进入。

BIOS的界面如下图所示，最上方显示本本的型号，左侧为功能树，右侧为目前状态及说明文字。

界面如此，操作方向也和Windows 资源管理器类似：用方向键上下箭头移动光标，用左右箭头展开/折叠子项目，按回车键进入设置，再按回车返回。

设置完后按ESC键，选择“Save/Exit”为保存退出，选择“Discard/Exit”为不保存退出。

有个小技巧，按Alt+F可快速恢复出厂设置。

BIOS界面图二、项目释义BIOS各项的意义，请看下表：这张表是Vostro 1400的BIOS，不同的硬件配置项目略有不同，比如高端Latitude本本会有指点杆、键盘灯的设置项。

三、各设置项详解及设置建议下面笔者对各项进行详细的介绍，并从个人用户出发，提供一些设置的建议。

屏幕上条目的中文含义，我将按显示的顺序从上到下，从左到右的进行解释。

A00IntroductionDell SupportAssist plugin for Dell OpenManage Essentials provides proactive support capabilities for supported Dell server, storage, and networking solutions. OpenManage Essentials interacts with supported devices that are to be monitored and receives SNMP traps. The SNMP traps are periodically retrieved as alerts by the SupportAssist client. The alerts are filtered using various policies to decide if the alerts qualify for creating a new support case or updating an existing support case.All qualifying alerts are securely sent to the SupportAssist server hosted by Dell, for a creating a new support case or updating an existing support case. After the support case is created or updated, the SupportAssist client, runs the appropriate collection tools on the devices that generated the alerts, and uploads the log collection to Dell. This information in the log collection is used by Dell technical support to troubleshoot the issue and provide an appropriate solution.This document provides information you require to set up OpenManage Essentials and SupportAssist, and thereby ensure that SupportAssist works as expected in your environment.Getting Started With Dell SupportAssistTo quickly get started with SupportAssist:1.Ensure that OpenManage Essentials is installed on the management server and is configured to discover thesupported devices in your environment. For information on installing, configuring, and setting up your environment for OpenManage Essentials, see the Dell OpenManage Essentials User’s Guide at /OpenManageManuals.2.Install SupportAssist on the management server running OpenManage Essentials. For information on installingSupportAssist, see the Dell SupportAssist Plugin For Dell OpenManage Essentials User's Guide at /ServiceabilityTools.3.If the management server connects to the Internet through a proxy server, you must configure Proxy Settings inSupportAssist. To configure the proxy server settings, click Settings → Proxy Settings , and follow the instructions on the screen.4.Configure the Administrator credentials of each supported device type in your environment in SupportAssist. SeeConfiguring The Default Device Type Credentials.5.Verify if the SupportAssist client is able to communicate with the SupportAssist server hosted by Dell by performingthe email connectivity test.
