It is very like ivrs_ioapic/ ivrs_hpet, which can override the dedicated BDF id mapped to HID:UID that was reported from BIOS's IVHD entry. If BIOS did not report a right BDF, we can resort to this parameter to correct it. > > -- > Regards/Gruss, > Boris. > > ECO tip #101: Trim your mails when you reply.
