are reserved. Bits 0-13 of word 87 are reserved. Bit 14 of word 87 shall be set to one and bit 15 of word 87

shall be cleared to zero to provide indication that the features/command sets enabled words are valid. The

values in these words should not be depended on by host implementers.

Bit 0 of word 85 shall be set to zero; the SMART feature set is not enabled.

Word 88: Ultra DMA Modes Supported and Selected

Word 88 identifies the Ultra DMA transfer modes supported by the device and indicates the mode that is

currently selected. Only one DMA mode shall be selected at any given time. If an Ultra DMA mode is

selected, then no Multiword DMA mode shall be selected. If a Multiword DMA mode is selected, then no

Ultra DMA mode shall be selected. Support of this word is mandatory if Ultra DMA is supported.

Bits 15-13: Reserved
