Otherwise Bochs uses OSS with the given device name.

b3b95e0d84 - ATAPI command 0x1A added (based on the Qemu implementation) 
- simplified media presence check for ATAPI 'mode sense' commands (accessing
  parameter tree not required)

46265689aa - PACKET-DMA feature now supported by all ATAPI commands 
* don't panic if byte count is zero in PACKET-DMA mode (the specs say that
    byte count is used for PIO modes. The behaviour in DMA mode is not
    mentioned, but seems to be ignored in that case.)
  * pci_ide: initialize sector size with the BM-DMA byte count (disk read
    commands will overwrite this value, some ATAPI commands are using the
    original one.)
  * non-disk-read ATAPI commands simply copy the buffer in DMA mode
