126 Normally, there is only
127 one file system on a CD-ROM disc.
132 The character-mode devices for the
134 driver should only be used for accessing the audio features of the
135 CD-ROM player as the performance on data is abysmal.
137 The current version of the driver uses neither the DMA or IRQ
138 features of the interface board, although it has an interrupt handler
139 for any IRQ requests that are generated.
140 Until the DMA features are
141 supported, the only interrupts that the board generates are those that
142 aren't supported by the driver anyway.
