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