136 The character-mode devices for the
138 driver should only be used for accessing the audio features of the
139 CD-ROM player as the performance on data is abysmal.
141 The current version of the driver uses neither the DMA or IRQ
142 features of the interface board, although it has an interrupt handler
143 for any IRQ requests that are generated.
144 Until the DMA features are
145 supported, the only interrupts that the board generates are those that
146 are not supported by the driver anyway.
