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)
