Summary
The driver checker package in Windows 2000 can improve stability and reliability, and you can use this tool to debug driver problems. In Windows 2000, kernel-mode components can cause system crashes or system faults and result in incorrect writing to drivers, such as early versions of a Windows

Scalability is one of the goals of the Windows NT/2000/XP design. Its Hierarchical driver model is the best embodiment of scalability. The implementation of layering depends on two important designs of the io manager: 1.

A device driver is a software module that deals directly with hardware. In Windows 2000, Microsoft introduced the plug-and-play feature of Windows 9x Based on the driver structure of Windows NT4.0, and introduced a new driver structure (WDM ). WD
As you know, Windows NT/2000 strictly divides the system into kernel mode and user mode to achieve its reliability. In the i386 system, the system corresponds to the ring0 and ring3 CPU levels respectively. In ring0, You can execute privileged commands and have access to any I/O device. To switch from user to core, that is, from ring 3 to ring 0, you must use a CPU-based door mechanism, such as door interruption and door invocation. Windows NT/

We know that Microsoft's Windows 2000 and Windows XP operating systems contain a large number of hardware drivers. Combined with its Plug and Play technology can automatically identify new hardware and load hardware devices required by the driver, greatly facilitate the installation and use of the system. However, in some cases, this feature may also bring us unexpected trouble. Recently, I have had several

I have to write down some of the problems that I have encountered many times. The lessons have been delayed for a lot of time.
Problem description
Write a code to connect to the Database SQL Server in Java;
As follows:
Import java. SQL .*;
Public class tosql2000 {Public static void main (string [] SRG ){String drivername = "com. Microsoft. JDBC. sqlserver. sqlserverdriver"; // load the JDBC driverString dburl = "JDBC: Microsoft: sqlserver: // localhost: 1433; databasename = Try"; // connect to t
and the screen will be black and no response will be returned; direct installation will not work.
Cause: Ubuntu 10.04/11.10 does not support the sandy bridge architecture well. drivers cannot be installed on HD 2000 graphics cards. Therefore, they cannot be installed on the wide screen.
Solution: after several days, I finally solved the problem. I found a lot of Chinese and English websites, which I summarized as follows:
1. Find a display with a squ
// Get the connectionPrivate connection conn = connectionfactory. getconnection ();// Generate operable objectsPrivate preparedstatement pstmt = NULL;
When a connection is used as a private field of a class, it may only be an instance, which leads to this error. (The reason is somewhat far-fetched)
Even the connection pool reports such an error.
Therefore, each method requires an instance of its own.
Adding multiple entity instances to the list does not allow spring injection of get. It
