It is a method of checking a given piece of hardware for ID codes.
These can include names (vendor and/or product), firmware revision, class,
or any other way to identify or detect its presence.

If it is questional/buggy/poorly designed/pre-standard release/etc...
You use an identifier and do a blanket feature disable.

This relates to VIA IDE chipsets, which there are several versions
with the same ID codes and different host-bridge ID codes.
Since there are questions about the early versions of the chipset,
some have suggested that we do a "BLANKET" disable of all (U)DMA
transfers modes regardless of revision. This would completely disable
all VIA chipset for IDE-(U)DMA modes. This would even include ones
which are stable/tested/valid/etc........ AKA dropping support completely
of the hardware in question.

Equal to shooting yourself due to a broken leg.

In both cases, time and work will prevent the death of something that
may/can/will work again in the future.

Cheers,
Andre
