# 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".
