SCSI Card VS Docking Station

I am trying to install an Adaptec 19160 SCSI adapter into my Compaq Docking Station, but to no avail.
Everytime I have the card inserted into one of the 3 PCI slots, the computer locks up on booting. (From the bootlog, right at the point where it starts running PCI.VXD.)
Adaptec insists the card has to be in a PCI slot, version 2.1 or newer. Compaq claims the slot is version 2.2.
All of my PCI devices are on IRQ11, per "Plug & Play".
I had installed the Adaptec software prior to installing the card, so it would just need to see the card & go from there.
The BIOS on the card is Adaptec's 2.57 (Latest version.)
I have tried disabling individual features of PCI steering and then disabled all of PCI steering, but no luck there.
The PCI slots work because I normally am running my NIC in one of them. When I have been trying to get the adapter card to work, I pull out the NIC.

Hi,
I dont know for sure that I have the fix,
but I lost alot of hair learning about SCSI, maybe I can save you some of yours. First, you cant (or should'nt) have 3 PCI slot's set to IRQ11, each slot need's it's own IRQ.
There is a such thing as IRQ sharing, but you very seldom want to use it.(you may need to change this in your computers bios setup)
Second,SCSI cards and NIC's often want to locate their BIOS routines in the same place, the way I would try to fix it is this,
1) Fix the IRQproblem, let PNP assign different IRQ's.
2) Uninstall the software.
3) Insert the SCSI card and let BIOS assign it an IRQ of it's own.
4) Start windows and open device manager, click on your SCSI card and solve any conflicts you might find there.
5) Re-install the software.
6) repete step 4
It might help to know what OS you are running, this should work for win 95/98,
If this does'nt fix it, and you want to let me know what came up on your screen when you tried it, you can e-mail me at loren19@trdesk.com
Good luck
