Thanks for the information, it has helped me (hopefully) to get to
the bottom of this.

The photo of the card you have clearly shows that it is not a Iomega
rebranded Adaptec (no Adaptec logo on any chip).

It seems to be a Iomega Buz video capture card (Advansys logo), the
same one as this on sale at FleaBay:

The AdvanceWare utility screen does not leave room for doubt with
respect to the OEM.

The Philips chip (SAA 7185B WP) located near the rear of the card is
actually a video encoder chip, and the Zoran chip (ZR36057PQC) is for
multimedia/video capture/editing use, all of which makes sense in a
video capture card.

A manual can be downloaded here:

Now, that is all very nice but the more I think about it the more I
see some hardware issue. ie: the card with your box and the system
not booting.

Maybe you need to disable the on-board video if you want to use the
Radeon card?

Here is a link for a set of manuals for your Pavilion a6345f:

Troubleshhooting and Maintenance Guide, PC Troubleshooting and
Advanced setup guide would be the ones to look at.

If you cannot make any progress, you may want to consider looking for
a used Adaptec card (AHA-2930U or AHA-2940U).

Just make sure that it has the external connector to match your
scanner's cable or be prepared to puchase a different cable to avoid
having to use an adapter.

It is a recipe for trouble.
ie: strain on the card's external connector.

Long ago, some SCSI scanners were marketed with a simple ISA/PCI
card, maybe it was the case with your scanner? If you could fine one
it would be ideal.

That's all I got, hope you solve the problem at hand.

Best,
