https://en.wikipedia.org/wiki/Bus_mastering
In computing, bus mastering is a feature supported by many bus architectures that enables a device connected to the bus to initiate direct memory access (DMA) transactions. It is also referred to as first-party DMA, in contrast with third-party DMA where a system DMA controller actually does the transfer.

Bus mastering is a bus architecture feature that allows a control bus to communicate directly with other components without having to go through the CPU. Most up-to-date bus architectures, like the peripheral component interconnect (PCI), support bus mastering. Bus mastering increases the operating system's data transfer rate, conserves system ...

Both EISA and PCI allow devices to initiate a bus transfer, therby becoming a bus mastering device, but not all all EISA and PCI cards and busses support bus mastering. For example, a bus-mastering capable PCI card might be installed in a bus or slot or system that does not support bus mastering.

This option determines whether the host adapter verifies the accuracy of data transfer on the SCSI bus. The default is Enabled. You should disable SCSI Parity Checking if any SCSI device, connected to the host adapter, does not support SCSI parity. DMA Transfer Rate This option determines the DMA transfer rate for ISA bus mastering host adapters.
