Users questions: This card is used to diagnose what the computer? Specific point! (No contact with this) about how much money does buy one?
Experts answer: diagnostic card works is to use the motherboard BIOS the internal self-test procedures in the test results, shown one by one through the code, with code, you can quickly know the meaning of Fact Sheet Computer fault lies. Especially in the PC machine can not boot the operating system, black screen, speaker is not called when using the card to better reflect its convenience, so you do more with less. BIOS boot each time, the circuit system, memory, keyboard, video parts, hard drives, floppy and other components of rigorous testing and analysis Drive system configuration, configured on the basic I / O initialization settings, everything is normal, and then boot the operating system. The salient features of the cursor as the dividing line is whether there is, first of the key components to be tested. Critical component failure to force the machine into the stands, displays no cursor, the screen no Reaction. Then, to test for non-critical parts of the faulty machine continues to run, but display no display when the card into the expansion slot. According to the code displayed on the card, refer to your machine which belongs to BIOS, and then identified by the code book, said the reasons for and location of the failure to Can clearly know the fault lies. 1, "C1" memory read and write the test, if memory is not plugged in, or the frequency is too high, will be BIOS that there is no memory, then the POST will remain in the "C1" Division. 2, "0D" said the graphics card is not plugged in or not, at this time, the buzzer will Beeps. 3, "2B" test the disk drive, floppy or hard disk controller problems, will show "2B". 4, "FF" for all parts that have passed all testing. However, if a boot on the show "FF", this does not mean the system properly, but the motherboard's BIOS appears A failure. Result may be caused by: CPU not plugged in, CPU core voltage did not adjust well, CPU frequency is too high, the motherboard has problems. Code AwardBIOSAmiBIOSPhoenixBIOS or Tandy3000BIOS00. Have shown that the system configuration ; Will control INI19 bootloader. .01 CPU Test 1, the processor state to verify if the test fails, the loop is infinite. Processor register test about to begin, non-maskable interrupt will be disabled. CPU register test in progress or failure. 02 to determine the type of diagnosis (positive Often or manufacturing). If the keyboard buffer containing the data is invalid. Disable non-maskable interrupt; by delaying the start. CMOS write / read in progress or failure. Clear 8042 keyboard controller 03, issue TESTKBRD command (AAH) power-delay has been completed. ROMB Check the parts in progress or failure of IOS. 8042 keyboard controller 04 to reset to verify TESTKBRD. Keyboard controller soft reset / power test. Programmable interval timer test in progress or failure. 05 If the manufacturing test is repeated 1 to 5, 8042 obtained control of state State. Identified soft reset / power; about to start ROM. DMA in progress or failure in early as prepared. The circuit chip 06 for the initial preparation, disable video, parity, DMA circuit chip, and remove DMA circuit chip, all page registers, CMOS shutdown byte. ROM has been calculated start ROMBIOS checksum, and check the keyboard buffer is cleared. Initial DMA page register read / write test in progress or failure. Test 2 07 processor, CPU registers to verify the work. ROMBIOS check sum of the normal keyboard buffer is cleared, the keyboard issue BA T (Basic Assurance Test) command. .08 CMOS timer to make the initial preparation, the normal update cycle of the timer. Keyboard BAT command has been issued, will write BAT command. RAM update the test in progress or failure. 09EPROM checksum passed only and must be equal to zero. Nuclear Real basic assurance tests of the keyboard, and then verify the keyboard command byte. The first 64KRAM test is in progress. 0A to video interface for the initial preparation. Send keyboard command byte code, is about to write command byte of data. The first 64KRAM chip or data line failure, shift. Test 82 0B 54 channel 0. Keyboard controller command byte is written, to be issued 23 and 24 of the blocking pin / unlock command. The first 64KRAM odd / even logic failure. 0C Test 8254 channel 1. Keyboard controller pin 23,24 has been blocked / unlock; NOP command has been issued. The first 64
