DS-1E supports PC/PCI and D-DMA protocols to emulate the DMA of SB Pro on the PCI.
In addition,
DS-1E supports the old type of interrupts used by ISA and the Serialized IRQ protocol.
The combination of PC/PCI and Serialized IRQ is recommended for DS-1E.
The system block diagram when using Intel chip set is shown below.
