Computer timed boot, automatic boot, automatic shutdown, network boot ......

Will you start the system? "If I ask you such a question, it will surely lead to a lot of bad eggs. But now I want to ask, "Do you know how many boot methods are available? "Certainly not many people can answer the question completely. In addition to power supply, you can press the power switch on the host panel to start the instance. There are also eight ways to start the instance. If you don't believe it, follow the objective s845e motherboard used by the author to test it!
First: timed boot is now supported by most computers. For example, I work at every day and set it to automatically enable my computer after every day. Oh, isn't that convenient?
Implementation conditions: first, confirm that the power you are using is ATX power, then check whether the CMOS settings contain "resume by alarm", "RTC alarm resume", or similar options (this option may be different from the setting value for different boards ).
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the "power management setup" menu and set the "resume by alarm" option to "enabled", as shown in 1. The following sub-options "date (of month) Alarm" and "Time (HH: mm: SS) Alarm" are activated to highlight, that is, the configurable status. Next, select the "date (of month) Alarm" sub-option with the direction key. This option is generally not set, but the default value is "0", indicating that it applies every day. If you do not want the system to start regularly on a daily basis, you can also customize the day on which the system starts. Use the arrow keys to move to the "time (HH: mm: SS) Alarm" sub-option and use the "page up" or "Page Down" key to set the system startup time, the format is "hour: minute: Second". This time is based on the system clock. Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. If the power is continuously turned on at the next shutdown, the instance can be started on a regular basis.
Step 2: Set "set supervisor password (set super user password)" or "Set User Password (Set User Password)" in CMOS settings. If the former is activated by the ATX power supply, you do not need to press the power switch on the front panel of the host to start the instance directly using the password. The latter must press the power switch on the front panel of the host, enter "set supervisor password" or "Set User Password" to start the instance.
Implementation conditions: Before enabling the hotkey, check that the 5 V standby current of the ATX power supply is not less than 300mA, then check whether the CMOS settings contain "power on function", "keyboard/mouse power on", or similar options (different motherboard, this option may be different from the setting value ).
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the integrated peripherals menu and set the "power on function" option to "password" (2 ). The following "kb power on password" sub-option will be activated to highlight, that is, the configurable status. Use the arrow keys to move to the "kb power on password" sub-option and press the Enter key. Enter the password. This key is only valid for 26 English letters, 0-9 Arabic numerals, and 0-9 Arabic numerals in the primary key area. Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. If the power is continuously turned on at the next shutdown, enter the previously set password to start the system.
Tip 3: The hotkey is different from the password when starting the system. You can set the hotkey to any key or combination key on the PS/2 keyboard when starting the system.
Implementation conditions: Same as "password Boot.
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the "Integrated peripherals" menu and set the "power on function" option to "Hot Key" or "any key", as shown in 3. If you select "Hot Key", the "hot key power on" sub-options below will be activated to highlight and move to the "hot key power on" sub-option with the direction key, set it to "Ctrl-F1 "~ One of "Ctrl-F12"; if you select "any key", you can activate the power supply with any key. Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. The next time you shut down, you only need to continuously turn on the power. You can set the hotkey before entering the power.
Tip 4: Few people hear that the mouse can be started through PS/2, right? In fact, it is very easy to implement, and the steps are similar to the Hot Key boot.
Implementation conditions: Same as "password Boot.
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the integrated peripherals menu and set the "power on function" option to "Mouse left" or "mouse right ), 4. Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. When the next shutdown, as long as the power is continuously turned on, you can use the left mouse button or right mouse to start up.
TIPS: some boards may also provide jumpers that enable hotkey boot and mouse boot. If so, they must be enabled.
Fifth TRICK: power-on automatic boot this boot mode is an alternative, as long as the host is powered on, the computer will automatically boot, instead of pressing the host front panel power switch.
Implementation conditions: first, confirm that the power you are using is ATX power, then check whether the CMOS settings contain "Soft-off by PWR-BTTN", "system after AC back", or similar options (different motherboard, this option may be different from the set value ).
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the "power management setup" menu and set the "soft-off by PWR-BTTN" option to "instant-on" (I cannot set this motherboard to this project ), 5. Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. In the future, you only need to connect to the power supply (if the power supply at the rear of the chassis has a switch, you can also use this switch to start the power supply. Under normal circumstances, the power supply should be activated in front of the power switch to start up.
TIPS: some boards need to be re-activated after power supply (for example, Asus p2b motherboard). Even if you have set the above settings, the computer will be activated for about 2 seconds after the next power supply is connected, that is to say, the power lamp will be on all of a sudden, and then you must press the power switch to start the computer. This is because the Asus p2b motherboard enables the computer to have the service host function, you can also manually turn off this function. You can see a three-pin jumper at the top of the AGP slot of the Asus p2b motherboard. You can see the words r27a and r27b next to the jumper. When the two or three feet are short, it indicates that the system is automatically started when the power supply is enabled. When the power supply is 1 or 2 feet short, the system is in normal mode.
The sixth trick is to start a call. "I only heard of the call display, but I have not heard of the call start. "This may have many questions. Indeed, the current computer can basically enable the power of incoming calls, but we do not use this function at ordinary times. We can even use the power-on function in the office to open the computer in our home and download the necessary files, and then shut down the computer in our home. Maybe you still don't believe that computers will be so intelligent? If you don't believe it, try it with me! Of course, it also requires some configuration and hardware cooperation to complete such work.
Implementation conditions: first, check that the 5 V standby current of the ATX power supply is not less than 800mA, and then check whether wor is provided on the motherboard (wake up on Ring, ring) plug-in (6), and then check whether the CMOS settings contain "Wake-up by ring/LAN" or similar network wake-up function options (different motherboard, this option may be different from the setting value), and then confirm whether the modem has the wake-up function (we can know whether the modem provides the wor interface ), finally, you need to buy a two-pin wor connection line to connect the wor plug-in on the motherboard (For details, refer to the motherboard manual) to the modem's wor interface. These five conditions are indispensable.
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the "power management setup" menu and set the "Wake-up by ring/LAN" option to "enabled", as shown in 7. Then, move the arrow key to the "Wake-up by PCI Card" option and set it to "enabled ". Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings.
To achieve this function, you must ensure that the modem must be connected to the telephone line and that the modem power and host power cannot be cut off. In the future, as long as you make a call to the home, the host power will be automatically turned on. To make the external connection successful, you must have appropriate software running (for example, a Windows 98 dial-up server) to remotely access the computer.
7. Network wake-up: for administrators, you can use the wol (wake up on LAN) function to remotely start the network, execute maintenance tasks, and then remotely shut down the network. You can also perform maintenance automatically, which greatly facilitates the administrator.
Implementation conditions: similar to the "Incoming call start" section, the difference is to change wor to Wol. In addition, the wor interface or connection line is two-pin, while the wol interface or connection line is three-pin, as shown in figure 8.
Implementation steps: Same as the "Incoming call start" section. In the future, if the computer is sleeping, the computer can be called through the network.
TIPS: if you are using a motherboard With an integrated Nic or modem, the motherboard has already been directly integrated with the network wake-up function, and no additional connections are required.
Method 8: Enable a USB keyboard. The last boot mode is to enable a USB keyboard. If you do not use a USB keyboard, do not be jealous.
Implementation conditions: first confirm that the 5 V standby current of the ATX power supply is not less than 800mA, check whether the CMOS settings contain "USB controller" and "USB kb wake-up from S3" or similar function options (different motherboard, this option may be different from the setting value), and finally confirm that the USB device is connected.
Implementation steps: after self-check is enabled, press the "Del" key to enter the CMOS settings. In the main menu, go to the integrated peripherals menu and set the "USB controller" option to "enabled", as shown in 9. If you are using a USB keyboard, set the following "USB keyboard support" option to "enabled ".
Press "ESC" to return to the main menu, go to the "power management setup" menu, and set the "ACPI suspend type" (ACPI standby mode) option to "S3 (STR) "or" S1 & S3 ", as shown in 10. The following "USB kb wake-up from S3" option is activated to highlight, that is, the configurable status. Set the "USB kb wake-up from S3" option to "enabled ". Finally, press the "ESC" key to exit the menu, select the "Save & quit setup" menu (or press the "F10" key), and press the Enter key to save and exit the CMOS settings. In the future, the computer will be able to wake up by pressing any key on the USB keyboard during sleep.
TIPS: some boards may also provide jumpers that enable USB device boot. If yes, they must be enabled.
