motherboard

问题 I was wondering if anyone knew if it was possible to change the BIOS POST Code that is displayed on the motherboard LCD. I want to develop a program that can manipulate the LCD screen on the motherboard to display any set of desired characters. I haven't been able to find anyone who has done something similar. Does anyone have any ideas on if this is possible? Thank You! 回答1: POST codes are usually displayed on LED devices on the motherboard, not LCD. Historically, POST codes can be output

问题 I used Win32_BaseBoard SerialNumber property to obtain the motherboard serial number and it work most of the time, but sometimes in some computers I get SerialNumber = "Base Board Serial Number" as a result. Is there a programmatic way to obtain this serial number in a more efficient way or it is simply a manufacturer problem? I have heard that all motherboards come with a serial number with no exception. Is this true? 回答1: Whether the Serial Number returned by various WMI queries will be

问题 I'm using WMI in C++ classes to retrieve the serial number of my motherboard. The query is the following : "SELECT SerialNumber FROM Win32_BaseBoard" I wrote the query myself so i'm not certain it is correct, but it does return something : /9637CW1/CN1296131Q0BA8/ . The returned string is in the same format on multiple computers so i assume the query is correct. My question is : am i really querying the motherboard serial number here ? Because i saw another class called "Win32

问题 How do I get the motherboard ID or serial number from Delphi code? Is there any example code or articles that I can look at? 回答1: try using the WMI Win32_BaseBoard Class . see theses samples: Option 1) before execute you need import the Microsoft WMIScripting Library from Component -> Import Component and then select Import type library program GetWMI_MotherBoardInfo; {$APPTYPE CONSOLE} uses ActiveX, Variants, SysUtils, WbemScripting_TLB in '..\..\..\Documents\RAD Studio\5.0\Imports

问题 I used the code from http://www.rgagnon.com/javadetails/java-0580.html to get Motherboard Id, but the result is "null". How can that be? Also I modified the code a bit to look like this to get ProcessorId: "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"+ "Set colItems = objWMIService.ExecQuery _ \n"+ " (\"Select * from Win32_Processor\") \n"+ "For Each objItem in colItems \n"+ " Wscript.Echo objItem.ProcessorId \n"+ " exit for ' do the first cpu only! \n"+ "Next \n"; The

问题 How can I get my motherboard's ID, using Java, in Linux, Mac, and Solaris? I'd prefer a cross-platform solution. I found a way that works in Windows: String result = ""; try { File file = File.createTempFile("realhowto",".vbs"); file.deleteOnExit(); FileWriter fw = new java.io.FileWriter(file); String vbs = "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n" + "Set colItems = objWMIService.ExecQuery _ \n" + " (\"Select * from Win32_BaseBoard\") \n" + "For Each objItem in

问题 I want to retrieve motherboard ID from a C++ program on Linux (Ubuntu) without root privileges. I know that dmidecode can do this, but it requires root privileges, so it is not suitable for my needs. Does anyone know of non-root alternatives? Source code will be much appreciated. 回答1: You don't have to be root to get the information, but you do need to have root first give you permission. Obviously root is allowed to secure access to their machine, and this includes access to hardware

问题 I'm trying to get the CPU serial or motherboard serial using C or Python for licensing purposes. Is it possible? I'm using Linux . 回答1: You need to use the CPUID instruction. CPUID Most C compilers have some support for inline assembly, but you will need to know what you are doing. 回答2: Under Linux, you could use "lshw -quiet -xml" and parse its output. You'll find plenty of system information here: cpuid, motherboard id and much more. 回答3: You can get the CPUID. Maybe linux command
