 # ATA (IDE) bus support
 atabus* at ata?
 
 # IDE drives
 # Flags are used only with controllers that support DMA operations
 # and mode settings (e.g. some pciide controllers)
 # The lowest order four bits (rightmost digit) of the flags define the PIO
 # mode to use, the next set of four bits the DMA mode and the third set the
 # UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
 # to use, and the last bit must be 1 for this setting to be used.
 # For DMA and UDMA, 0xf (1111) means 'disable'.
 # 0x0fac means 'use PIO mode 4, DMA mode 2, disable UltraDMA'.
 # (0xc=1100, 0xa=1010, 0xf=1111)
 # 0x0000 means "use whatever the drive claims to support".
