FYI, you may want to add this table to your summary.

The IDE modes are
	PIO 		0-4
	Single word DMA	0-2
	Multi word DMA	0-2
	Ultra DMA	0-7

This configures the disk - not the chipset.
	-X00	restore default PIO
	-X01	diasble IORDY

PIO=mode + 8		Programmed IO
	-X08	PIO 0
	-X09	PIO 1
	-X10	PIO 2
	-X11	PIO 3
	-X12	PIO 4

SDMA=mode + 16		Single-word DMA
	-X16	SDMA 0
	-X17	SDMA 1
	-X18	SDMA 2

MDMA=mode + 32		Muti-word DMA
	-X32	MDMA 0
	-X33	MDMA 1
	-X34	MDMA 2

UDMA=mode + 64		Ultra DMA
	-X64	UDMA 0 (ATA 16)
	-X65	UDMA 1 (ATA 25)
	-X66	UDMA 2 (ATA 33)
	-X67	UDMA 3 (ATA 44)
	-X68	UDMA 4 (ATA 66)
	-X69	UDMA 5 (ATA 100)
