●It do no harms to device while insert the card wrongly with a speaker on the card to remind you there is an error, SMD device that protect your hands.

●Test the speed of PCI and ISA bus of the computer, you will get the result as soon as you test

it. It can help you not suffer losses when you buy the computer, and also help you sell the computer that has a fast bus speed at good price. .

Illustration of four-bit code POST card (5004 version)

code analysis clew

The codes that can be consulted are last 0 to 47 codes that take relative longer time in the POST process, not all the code need to be consulted.(some main board output millions of codes or the same code appears many times), If the same code take different time to run in different running courses on the same main board , the POST card not always use it as code that can be consulted. The main board is of the good stability If the 47 codes that consulted in different running courses on the same main board are the same, and the last 47th code has passed the POST, but this situation is rare.

Ⅳ、Distinguish true and false

Pi0050is more suitable than Pi0049for slap-up main board ,such as pill、PIV and so on. So you can distinguish them by their characteristics ,and also you can dial this number 086 139 **** **** or write to me by E-mail:p678@http:// to get lastest distinguishing message.

There are typefaces like “China Copyright 01224987.4”on the edge of

PCB;

There are typefaces like “China Copyright 513427”on PI0049、pi0050;

●On the back of the card ,there is a telephone number written like “086

139 **** ****;

”中国专有号：01223987.3”

●”专有技术：01224988.3”

●”专利号：02125087.5”(It is the patent of biology organic compound)

●Be careful .The spurious cards always use badly or unsuitable materials, it hasn’t been tested by the professional equipment ,and has no simulation technique.

●At the same time ,there may be a few low card appears to used as PI0050 card.

Ⅴ、OBLIGATORY CONTENT

1. The error code table is in the order of the code value that from small to big. The sequence that the code displays is decided by BIOS of the motherboard;

2. Four-bit code can be divided to two two-bit codes .The one is made of the thousands digit and the hundreds digit ;The other is made of the tens digit and units digit .According to the two two-bit codes, Not only you can know the posting for computer can not pass the units that the thousands digit and the hundreds digit point out, but also you can know that the post for computer can pass the units at last that the tens digit and the units digit point out;

3. Code haven’t be defined is not included in the table;

4. For the different BIOS (such as A …… 此处隐藏：3915字，全部文档内容请下载后查看。喜欢就下载吧 ……
