PCI 2.2 spec - Subsystem ID and Subsystem Vendor ID Regs



Title: PCI 2.2 spec - Subsystem ID and Subsystem Vendor ID Regs

Hello-

In the 2.2 spec PCI SIG choose to make using the subject registers mandatory.  Can it be assumed that older controllers that reserve these registers and make them 0 will still be useable in systems that check these IDs and boot time???  Will incompatibility cause BIOS hang ups???  WIN2000/NT config problems???
