Subject:  HPIB problems


Your problem was forwarded to me by a co-worker who monitors the VEE

What HPIB card are you using?  The reason I ask is this:

On our NT systems, you cannot see our Hewlett-Packard HPIB card in Windows
NT Diagnostics !!

You may be misinterpreting another card as the HPIB card.  So we first look
at the available IRQs and then set the board to one that is available.
Even after everything is working, you still cannot see the HPIB card in
Windows NT Diagnostics.  Only the IO Config program sees it.

Another possibility is plug and play (PCI) bios (even though NT doesn't
support plug and play).  If you have plug and play bios, it may only have
one available IRQ left for PCI cards.  If the HPIB card and ethernet cards
are PCI they may be forced on each other by the PCI bios.

My suggestion is to pull the ethernet card completely.  Go through the HPIB
installation and see if it works properly.

Sorry I can't pin point exactly, but we have seen problems like this before
and they were solved by careful management of IRQs.  In one case, just
recently, we were forced to remove a PCI Ethernet card which received it's
IRQ from the BIOS and replace it with an ISA card which had a setup
utility.  That solved the problem of 2 PCI cards trying to grab the same IRQ.
