But why? Why do we have to emulate the entire HBA for the BIOS? The HBA is emulated, too, and just uses the bdrv interface internally anyway. So IMHO it makes far more sense to skip the HBA emulation in the BIOS completely and just use the bdrv interface directly here.
If you use the bdrv interface (ala extboot), you couldn't boot via scsi passthrough.
VirtualBox implements a paravirtual SCSI bus to allow SCSI boot without having to implement a full LSI driver. That's another way to solve the problem.
