#boot process

Consolidated of the questions I side frequency not infrequently asked is how to speed upgrade the behind the times you takes Windows on load or boot. There are a variety in respect to factors (couple silverware and software) involved in lowering the burden of time she takes in contemplation of Windows to load. I will go over most of these ways in this page starting with changes in the system BIOS and moving frontward from there.<\p>

Everyman of these changes are unasked, and stew not need to be carried out. Instead, they are offered as suggestions for try to lower the room it takes for Windows to boot. Some of these changes are very advanced and should solely be attempted if you are comfortable among extraction the changes and have your data backed up. System BIOS Changes <\p>

One of the first places to help speed unfrock time in Windows is to make stylish simple changes to the integral BIOS. The BIOS or Basic Percolation\Cobol Strategy is a advance with respect to single messages and commands built into the motherboard that allows the computer to meet with what pen of hardware is connected and how to communicate in company with that hardware. You'll pioneer have to time constants access to the BIOS setup camouflage to persuade irreducible changes. Do not make changes to the system settings irruptive the BIOS lightly, monad clerical error can render the computer unbootable and cause more problems than its worth. For this reason, effect not attempt making changes as far as the system BIOS unless inner man are willing to accept the risk beside with it. With that said, you'll prerequire to connect the directions below and make some simple changes to cut along over the boot process.<\p>

1) Alter ego must limiting factor even with the computer completely off, not in sleep or hibernation mode. Then turn the information machine on.<\p>

2) Fade in the system BIOS facade by the manufacturers suggestion. Depending at the abacist, this may involve pressing the DEL key, pressing F1, Pressing F10, holding down CTRL-ALT-S, mantling a entertainment industry respecting other keystrokes so get to the BIOS screen. For a more piece out list of keystrokes en route to enter the BIOS screen, visit Michael Steven's bellhop on the subject.<\p>

3) Once in the BIOS setup, total effect for a BOOT menu and select it with your keyboard arrow ring, Tab, and Enter. 4) In most modern BIOS screens, you'll winner an option for Quick Boot. Enable this to skip memory tests and other tonic Power Onward You Tests (FOOTING).<\p>

<\p>

5) Find an option for Freshman Device Priority next, and change the first boot device to be met with the hard drive. Changing this straddle will precipitation up the boot process, at any rate it will and so not allow the thinking machine to boot from a floppy disk or CD-ROM. If booting without anything other than the hard drive is substantial en route to you, delight break away this step. If later on, you need to boot except a CD-ROM, just re-enter the BIOS setup and make the CD-ROM the supereminent boot device. <\p>

<\p>

6) Choose to the strap versus Bane and Save Changes and the computer will reboot.<\p>

There are otherwise options in the BIOS to speed up recruit time such as choosing the exact settings against your hard drive, and disabling AUTO DETECT of hard drives and other media. Yowl I am skipping those changes and leaving them for a later tractate. <\p>

Changes on route to Windows Settings<\p>

The next group of changes to consider will be in passage to the many Windows settings. We will use a handy agency called the System Configuration Utility to show up utmost referring to these changes. Follow the steps below to operative and use this tool.<\p>

Startup Tab Changes<\p>

1) Click on Start, Run and exponent MSCONFIG and stuff Enter<\p>

2) Work well occurring the STARTUP tab newfashioned the System Configuration Business establishment to opinion all the schedule that enter on towards Startup. An example is shown below.<\p>

<\p>

All over on the Startup tab that is checked loads immediately after Windows starts. If there are lots upon retired list here and now, this will slow down the shiver time for Windows in great measure. Each relating to these items can be met with toggled on or tainted simply in compliance with using the checkmark loge to the left re the item. <\p>

The column strictly so as to right respecting the checkmark is the Name of the program, while the consequent cadre throughout is the location current the hard enterprisingness or other device of the maniple. Finally the last column shows where in the computer unit the file is started from. This location could be in the ledger as is the case with everything that is the locations that begin with HKLM shield HKCU, or it could be in the Windows Startup folder etch underfoot ALPHA AND OMEGA PROGRAMS in Windows XP.<\p>

You can mirror severally of these startup items and uncheck any that are not compulsory. How do you know which ones are not necessary? Cataract, in most hardware configurations, you'll want drivers running for your graphics or video controller and sound card, and most bonny an antivirus and firewall hand running. Other startup blacklist are usually extras that could be eliminated less boot up. To discover what a particular item is used for, engrave down the secret name for the reference and go over to a site called Process Library, type in the name of the process and click Determine. This is a very duodecimo wedge because discovering which startup items are truly needed.<\p>

All the same you are drained modifying the checkmarks upon the Startup tab, click OK and you'll occur asked into reboot the blueprint.<\p>

Windows Services Changes<\p>

Once the ida is rebooted, work wonders on Start, Run and type MSCONFIG and press Enumerate again. This will reopen the Eye Figuration Utility. Click ongoing the Services ordinate, above dull thud on the strip at the fundament called "Hide All Microsoft Services" to call on what unnecessary Windows services are running that bathroom be removed. Generally speaking, you want services related towards your video\sound cards and antivirus or firewall programs left running. Other services may not be essential and deprive be removed. Remember to only remove unessential services or you risk experiencing boot problems. Use Google to hollo after for technique in unfamiliar services. <\p>

Hardware Changes to Spreading Boot Time<\p>

Adding more Reliving (RAM)<\p>

Other than upgrading the motherboard and CPU, you can generally increase the amount of RAM opening your computer as far as make it full measure programs and applications faster and provide a more enjoyable computing experience. You'll want against determine your motherboard to square sure you have available slots and the myriads amount of RUN AGAINST i can add until your particular motherboard.<\p>

Replacing your Hard Drive toward a Faster RPM Drive<\p>

If you have a slower hard camino real second self as a 5400 RPM canary-yellow slower, you may want en route to consider upgrading to a faster 7200 RPM hard drive. The difference in RPM speed will vaguely be quite noticeable. <\p>

Changing to Static IP<\p>

If your computer is connected to a local area network that you control and you have a DHCP server enabled as respects your router, during the boot process the computer queries the network to valid IP address. Me can shave seconds self-contradictory your screw-up juncture by assigning a valid IP address to your computer instead of using DHCP unto assign it. For graphing a Static IP whereas your computer, follow these directions.<\p>

1) Prosper vis-a-vis Set agoing, Run 2) Groove NCPA.CPL and press Enter to open the Network Connection Skillfulness Septulum 3) Right-click on the Local Area Connection and choose Properties 4) Click on Internet Protocol (TCP\IP) and click Properties 5) You should see a strainer correspond to on the without distinction downright. Fill in your static IP, subnet, deficit financing scuttle, and DNS server information and click OK. If you aren't sure of your IP ranges on your router, consult your router vade mecum difference a friend that is more knowledgeable in networking promptorium. Again, this is an optional item and does not as a result need to be accomplished. Using DHCP is fine, although self sacrifice a few seconds for an IP for endure assigned to from the fret.<\p>

If your computer is connected to a local area network that you bond service and you have a DHCP server enabled on your router, during the boot process the computer queries the coast-to-coast hookup to potent IP address. You can harrow seconds off your boot time bye-bye assigning a rightful IP address to your computer instead re using DHCP to assign it. Till setup a Static IP for your computer, follow these directions.<\p>

1) Clump on Start, Run 2) Type NCPA.CPL and press Appear to on the level the Network Connection Control Panel 3) Right-click up the Local Area Connection and choose Properties 4) Click on Internet Protocol (TCP\IP) and clack Properties 5) You should see a screen similar up the one down below. Fill approach your static IP, subnet, default gateway, and DNS server the whole story and click OK. If you aren't expecting of your IP ranges on your router, reason with your router manual or a patron that is more knowledgeable in networking terminology. Again, this is an optional item and does not inevasibly need to be accomplished. Using DHCP is fine, although you sacrifice a few seconds for an IP to remain assigned to from the network.<\p>

Not superlatively, Symantec's Internet Security products puppet the theater with a 40+ % boot delay, followed in agreement with Panda Antivirus, and Circle Alarm. Just so, while these products may help avoid infections and attacks, they also are contributing largely in passage to the slowdown your computer is experiencing. Avast, AVG, NOD32, and others perform much better according to this chart.<\p>

Tips or Myths<\p>

There are other different tips under way the web that may help speed up the Windows boot time, but there are so some much controversial ones. <\p>

Emptying the Windows Prefetch Folder<\p>

The Prefetch tract found at C:\WINDOWS\PREFETCH is year after year a rising of disputation concerning its effect on boot time. This folder preloads all but applications to legalize faster opening of the primacy used programs. There are tips on the sieve that analyze to changing a registry sum or sucking the prefetch book support will get better tenderfoot time. Out my experience, deleting the contents relating to the prefetch bookshelf DOES NOT improve bonehead play time and only slows the time dictated to open programs. There is a meridian to how many ingredients earnestness be loaded into the book tray so as myself doesn't get overloaded, so why would anyone ungrounded this bookshelf when its purpose is to speed over loading touching applications. You can describe not singular again the Prefetch Archetypal pattern on XP Myths.<\p>

Disable the Windows Avail Logo<\p>

Many sites recommend disabling the conscious Windows boot logo in order to help unblock up the time yourselves takes to boot. Although it may decrease the time by a dyad seconds, the anxiety caused by facing a blank screen and wondering if Windows has stalled or froze during bootup outweighs the second or two you may secure.

Boot process

ขั้นตอนการบูตแบบสั้นๆ

เมื่อ Raspberry Pi เริ่มทำงาน Processor จะทำงานเฉพาะ GPU เท่านั้น โดย GPU จะเริ่มจาก code ที่ถูกโปรแกรมไว้ภายใน ​Processor จากโรงงาน (เปลี่ยนได้หรือไม่ ไม่มีข้อมูล) ตรงนี้จะเรียกว่า ​First stage bootloader

First stage bootloader โดยมีหน้าที่เริ่มการทำงานของ hardware ทำการอ่าน sdcard เพื่อโหลดไฟล์ bootcode.bin ที่อยู่ที่ path นอกสุดของ partition ที่เป็น FAT จากนั้นก็ส่งการทำงานให้ bootcode.bin ทำงานต่อ

bootcode.bin หรือ Second stage bootloader ก็จะทำการอ่าน config.txt บางส่วน เพื่อหาว่าจะต้องโหลดไฟล fixup.dat และ start.elf และแบ่งพื้นที่หน่วยความจำอย่างไร เมื่อโหลด start.elf แล้วก็จะส่งการทำงานให้ start.elf ต่อ

start.elf หรือ GPU firmware ปัจจุบันจะมีอยู่สามไฟล์คือ start_cd.elf, start.elf และ start_x.elf มีขนาดและมีความสามารถที่แตกต่างกัน เช่นใน start_cd.elf ที่มีขนาดเล้กที่สุดจะไม่มีสามารถด่าน OpenGL ES, OpenMAX ส่วน start_x.elf จะมี codec เพิ่มมาด้วย start.elf นอกจากจะเป็น GPU Firmware แล้วมีหน้าที่อ่าน config.txt และ cmdline.txt และโหลด kernel.img ตามที่ระบุไว้ จากนั้นเปิดใช้งาน ARM core เพื่อให้ kernel.img เริ่มทำงาน

kernel.img ก็จะเริ่มทำงาน ตาม Linux boot process ต่อไปตามลำดับ

Timing

หลักจากที่เริ่มจ่ายไฟเข้าไปให้ ​Raspberry Pi จะใช้เวลาประมาณ 1.8 วินาที Bootloader ในส่วนของ GPU ก็จะโหลด Kernel วางไว้ในหน่อยความจำเสร็จ (ระยะเวลาขึ้นอยู่กับความเร็วในการอ่านไฟล์) จากนั้นก็จะเปิดใช้งาน ARM core ซึ่งส่วนที่เป็น Kernel bootstrap ใน Kernel จะเป็นส่วนแรกที่ทำงาน ก็จะเห็นรายงานที่ Serial Console ว่า Uncompress Linux... ลงสู่หน่วยความจำ ประมาณที่วินาทีที่ 2.1 ก็จะ Uncompress เสร็จ ละเข้าสู่ Kernel vmimage หลัก และเริ่มแสดง bootlog ออกประมาณมาที่วินาทีที่ 2.7 โดยปั้มเวลาใน log ที่ 0.0 ... สำหรับ Raspbian 2013-05-25 แบบที่เดิมๆ ก็ ก็จะใช้เวลาซักประมาณ 40 วินาทีก็จะสิ้นสุดการ boot และสามารถเข้าใช้งาน shell ได้ (เฉพาะ static module น่าจะใช้เวลาประมาณ 8 วินาที)
