If the circuit diagram, look directly at the following picture: Note: b is the base, C is the collector, E is the emitter If the specific components, the method is as follows: I, judging the transistor base For the NPN transistor, with a black Watch pen to connect an electrode, the red pen is connected to the other two electrodes, if the measurement results of a small resistance, the exchange of the pen after the measurement results are larger, you can determine the first measurement of

interrupt 10, this is finally found the problem lies, and sure enough USB device and modem there is a conflict. This apparent interruption of conflict is "blind to the eye" for Windows systems. Reason to find, and then should be a good solution to this problem.In fact, the solution is very simple, open the chassis, the built-in modem from the PCI slot to take down, reboot and insert a USB flash drive, the flash drive can be used normally. But every time using a USB flash drive can not take down

power supply, vss= digital ground, vee= negative power supply Another explanation: VCC and VDD are the power side of the device. VCC is the positive of the bipolar device, and VDD is mostly a single-stage device. The subscript can be understood as the collector C of the NPN transistor, and the drain electrode d of the PMOs or nmos field effect tube. Also you can see Vee and VSS in the circuit diagram, meaning the same. Because the mainstream chip structure is Silicon NPN, VCC is usually positiv

You can add your own scripts to the PE system by modifying one of the Startnet.cmd, Unattend.xml, and Winpeshl.ini files. We can create custom Winpeshl.ini files so that we can run our own applications. Now follow the actual combat. Before adding any custom scripts to PE, you must first load the basic WinPE image (Winpe.wim) with the ImageX tool. First, add custom scripts using Startnet.cmd, and use Startnet.cmd to add custom command-line scripts in WinPE. By default, WinPE includes the Startn

who compatible, such as 3c509,ne2000, EtherExpress and so on. Such models are generally on the network card on the largest chip on the printed, copy down is the. Perhaps the most common use of the network card is probably the best Ne2000 compatible card, I use it as an example. Note that many inexpensive cards are actually NE2000 compatible. For NE2000 card, the first thing to do is to set the NIC to jumpless mode. Many of the current network cards are by default

before attempting to use any version 2 function. A PNP driver calls Iogetdmaadapter when its AddDevice routine was called or when it handles a PnP irp_mn_start_device reque St for a device. This IRP is includes information about the device's hardware resources, the driver must supply in the DevicedeScription structure. The caller uses the MaximumLength member in the devicedescription structure to indicate

wait for the user to log on; 9. After the user logs on, the shell control system is started (if the user logs on to the GUI, the GUI is run ). The following describes the steps in the process: 1. Load BIOS When the system powers on, it first reads BIOS information. BIOS (Basic Input/Output System) is the underlying interface between computers and peripherals. It stores the data first loaded when the computer starts, including: CPU type, boot device sequence, hard disk size/type, chipset working

wireless Nic drive CD to the optical drive to complete the NIC Driver Installation task. If the system cannot automatically identify the wireless network card, you need to check whether the corresponding port function on the computer has been enabled. For example, when installing a USB wireless network card, once the USB port on the motherboard is not enabled, the system cannot identify the wireless network card. At this time, you can go to the "Device Manager" interface of the system, check wh

didn't use Windows 95 much (I thought it was a vase at that time). I used Windows 98/Me/XP for a long time, vista has been used intermittently. Windows is doing a very good job in its compatibility. For different hardware and software, if you have used DOS, you should know how difficult it is to install a sound card under DOS. PnP (Plug and Play, Plug-and-Play) does provide a good standard for the industry (although the early

If you download a package that does not contain the pnp component, you do not need to execute the package. I am using 1.8.4 in Chinese. It may be the negligence of the Chinese author. In the make al

If yes, it will load the usb driver program on the primary Eni ,?? D. try to mount the usb file system. 3. decide whether to start SELinux: what SELinux we talked about in chapter 17th is at this time? Perform some checks ,??

Plug and Play manager when a mobile device is plugged into a computer PnP (Plug and Play) accepts the event and queries the USB device's firmware (firewre information) for a description of the device (manufacturer, model, serial number, etc.). When the device is recognized, create a new key value

compatibility of the limited board is poor. Although it is a plug-and-play (PNP) device, it may not necessarily work well with the motherboard or operating system. When it is not working properly, to avoid interruptions and I/O address conflicts, you can change the pnp OS installed option in Bois. (3) When the network card works normally and the network cable is normal, you can only see the local machine

pull-up resistor, if there is a pin output logic 0, the equivalent of grounding, parallel with the circuit "equivalent to a short circuit", so the logic level of the external circuit is 0, only the high power, and the result is logic 1. on the push-pull output and open-drain output, and finally with a simple graph to summarize: the left side of the graph is the push-pull output mode, wherein the comparator output high power at the time below the PNP

output can output high, low level, connect digital devices; Push-pull structure is generally referred to two transistors by two complementary signal control, always in one transistor on the time of the other cutoff. The high and low levels are determined by the IC's power supply.Push-pull circuit is two parameters of the same transistor or MOSFET, to push-pull mode exists in the circuit, each responsible for positive and negative half-cycle of the waveform amplification task, the circuit work,

All other circuits satisfy the first original. Picture 1 is for dual-supply operation, picture 3-bit PNP type, DC +UCC from E inflow, vi

flexible output mode, but also has its weaknesses, is to bring the rising edge of the delay. Because the rising edge is the load charging through the external pull-up passive resistor, so when the resistance choice hour delay is small, but the power consumption is large, and the delay large power consumption is small. Therefore, if the delay is required, it is recommended to use a falling edge output.4, multiple open-drain outputs can be connected to a line. With a pull-up resistor, the "and lo

The WDM driver has a special AddDevice function, which is called by the PnP Manager for each instance. The prototype is as follows:NTSTATUSAddDevice (IN PDRIVER_OBJECT DriverObject,IN PDEVIC
