we're using WinXP on a brand new PC with for PCI Slots and one PCIe.
Before, the card worked fine on WIN98 with exactly the same number of PCI cards in the PC; this was an PII double processor at 300MHz each.
BUT, in fact, the error mysteriously disappeared on its own. I only disconnected and reconnected the cable while the computer was turned on without changing any other parameter (I don't know if this is recommended ?!) but know now more error messages ... I don't know if WinXP reconfigured upon this, but hey, funnily enough, it solved the problem.
I don't know. We've got 4 cards in this machine. It is a brand new PC, but it has "only" a 380 W power supply. So it may be that, but I always thought if there was not enough power, the PC would not start up....
Anyhow, hope the problem does not come back
