That seems to be a specific HP PCI card.
Maybe it's possible to pass-through it at some point in an emulation ?

^ this one isn't implemented yet in qemu.
As I said in another mail, we currently emulate a PCI SCSI card instead.
Maybe emulating the original SCSI controller isn't hard, but I don't know
and I'm not a SCSI expert.

^For that LASI LAN I do have code, but it doesn't work yet.
In HP-UX it fails the self-tests, but in Linux it works.
Still need to bring it upstream at some point.

I think the SCSI controller is the biggest issue for now...
If that works, the installations should continue.
