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
