My question is
regarding the XIO2000Achip hosted on the Startech PEX2PCI4 PCI Express to PCI
breakout box. We have a bespoke PCI acquisition card which uses the AMCC
S5935QRC chip. For many years we have been supporting a system consisting of XP
machines hosting two of these PCI acquisition cards. The customer wants to move
to Windows 7. As it is almost impossible to get rack-mount Windows 7 machines
with two PCI slots we decided to use the Startech PEX2PCI4 solution. To cut a
long story short the PCI cards did not function in the breakout box in the same
way as they functioned in internal PCI slots in exactly the same Windows 7 (32-bit)
machine. After many tests my colleague has come to the conclusion that the
XIO2000A chip is asked for control of the PCI bus and never grants it which
causes the machine to hang. Have you ever heard of such an issue? Are there any
registers on the XIO2000A chip which are configurable by the userwhich may solve this issue?
