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 falsePi0050is more suitable than Pi0049for slapup 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 2517 4332 or write to me by Email: to get lastest distinguishing message.TRUE ●There are typefaces like “China Copyright ”on the edge of PCB。 Press and hold the function switch for second, then enter the forward consulting mode and display P, after half a second, the code is displayed, the first twobit code indicates the zero code。 press and hold the function switch for some second, then enter the backward consulting mode and display P , after half a second, the code is displayed, the first twobit code indicates the 47th POST code, the last twobit code(47) indicates the ordinal number of the code。s guide is fit for the mon puter post card (the PI0050) and the note book puter post card (M04). 四位代碼形電腦主板故障診斷卡使用說明（There are editions in Chinese for you to choose）可選配中文說明書● Not only diagnose the trouble of main board but also the trouble of the POST card, keep users from misunderstanding .● More patible with main board PIV, end the history that the POST card is unable to work as the main board update constantly.● You can consult the code that has run。the code of version 5004 is more credible ,POST card selftest is more detailedUser39。s guide of fourbit code POST card This User39。 Press the switch once and the code pauses● 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 puter, you will get the result as soon as you test it. It can help you not suffer losses when you buy the puter, and also help you sell the puter that has a fast bus speed at good price. .
