What is POST Card function ?
The primary function of POST card is display the POST code during system BIOS
perform the Power On Self Test (POST) function.
How to select the POST Card?
The primary function of POST card is display the POST code. It is no performance
consideration for using the POST card. Using the different bus type POST card will get
same result for POST code indication. The only reason will be considered is the tested
motherboard must have the empty same type bus slot to plug in the POST card.
If you plan to used the POST card in older motherboard (such as 286, 386, 486),
we suggest to chose the ISA type POST card. (Since some older motherboard
didn't offer the PCI bus)
If you plan to used the POST card in current market motherboard, we great
suggestion to used the PCI bus type. (since the PC 98 specification : ISA bus is
option, PC 99 specification suggests no ISA bus slot, we think ISA bus will be
disappear for new motherboard. In fact the Intel new chipset is no ISA bus
function now)
If you are a engineer to maintain a wide range generation PC, you must select to
use both ISA and PCI bus type POST card.
For notebook user, we suggest you to buy the JET-1054 Mini PCI POST card (for
Mini PCI bus type III, most of new generation notebook has this kind extension
bus)
What is new generation PCI POST card design?
New generation PCI POST card is designed with the PCI bus core logic and ASIC
technology. It can work in any kind motherboard designs with PCI bus. (For the past
simple GALs designed version, it just pure designed the PORT 80/84 address decoder, it
can't work in new motherboard designed that will disable some PCI signal's function
when no PCI card plug in to solve the EMI problem and reduce system power dissipation
. For this kind motherboard, if you used simple decode POST card, it will lose the POST
code readout function during POST testing. )
We create the another new auto port 80/84 switch function in new generation PCI POST
card. It can auto switch to port 80 for general motherboard , switch to port 84 for Compaq
motherboard after system power on. In new generation designed, it will not display
abnormal post code and real perform the auto-switch between port 80 and 84.
Instruction guide for using the POST card
Turn off the system power firstly.
Plug the POST card into empty slot that same as POST card type for tested
