VSCom PCI 200L IRQ problem

I have a new box with an Intel D865GBF board, a Lucent WinModem and onboard Video, audio , Com1 and Lan.  It is a new install of Win 2K pro SP4. I need to add 4 COM ports so I bought 2 VSCOM PCI 200L cards.  I installed them using the drivers on the CD ROM for Windows 2000 and they are configured to COM 4&5, and 6&7 respectively.  Before I installed them I checked the Device manager and found I had IRQ's 2,4,5,7,10,11,12,20,21,22 open.  The BIOS was set to allow BIOS to configure IRQ's and all the PCI slots set to Auto.  When I put the first card in it was assigned IRQ 17 which is where other hardware already was.  There is no way to change the IRQ and putting it in a different slot did no good.  However Device Manager did not show any conflicts.  

I put the Second card in and it was assigned IRQ 18, no way to change it, no conflicts in Device Manager.  The machine boots fine with the cards in it and all looks good (except for the fact that WIN2K put it on already used IRQ's.)  However, as soon as I put any device on the com port, including a gender changer, the machine blue screens at boot with an error message about IRQ's.  I go into safe mode and look at device manager but can't do anything about the problem.  I have tried switching PCI slots, assigning IRQ's in the BIOS to the PCI slots (which are ignored) but cannot get this to work.  I have wondered if I had a bad card, but it seems strange that I might have 2 of them.  any ideas?

I would say it may be a compatibilty issue with windows 2k, is this card listed in the hardware compatibity list?

also pci cards should be assigned an automatic irq without any user intervene, pci cards may share an irq as well

I cannot find it on the HCL, I know the PCI cards "should" not require any user intervention but it is not working on it's own so I guess I have to intervene  :-).

The cards are not sharing IRQ's with other cards, but with built in hardware.  Does anyone have any other ideas or what ways I can get additional com ports?  Perhaps someone knows some card that is on the HCL.  Since MS does not list them in that way, I could not really find one when I perused the HCL.

yeh, then your best shot will be the card manufacturer, did you try to contact them or find their web site, I used a card before about 7 years ago, sorry can not remember what brand, it simulated 8 com ports and the coms where RJ45 like the network connection, I used on NT anf was for modem sharing software for a call center, it was running like a charm and installation wise was really easy, but again can't help as i can not remember, did you read any readme files with that card  installation files?

cheers

I checked the web site and all that was there was drivers and the same info that came with the card.  There was no link for tech support only sales and I have already sent them a message that has not been responded to.  The store who sold it to me checked it on one of their machines (XP) and said it worked but they were going to charge me $90.00 to check it on my machine.  After much calling around and praying, I found one card that had a left over Mercury PCI Dual Port Serial card that had been special ordered and the customer never picked it up.  It was about 25% cheaper than the VSCom card  and it worked.  It is not on the HCL list either.  So problem is solved .  THank you.
