66 * PIIX4 errata #9 - Only on ultra obscure hw
67 * ICH3 errata #13 - Not observed to affect real hw
70 * Things we must deal with
71 * PIIX4 errata #10 - BM IDE hang with non UDMA
72 * (must stop/start dma to recover)
73 * 440MX errata #15 - As PIIX4 errata #10
74 * PIIX4 errata #15 - Must not read control registers
75 * during a PIO transfer
76 * 440MX errata #13 - As PIIX4 errata #15
77 * ICH2 errata #21 - DMA mode 0 doesn't work right
78 * ICH0/1 errata #55 - As ICH2 errata #21
79 * ICH2 spec c #9 - Extra operations needed to handle
80 * drive hotswap [NOT YET SUPPORTED]
81 * ICH2 spec c #20 - IDE PRD must not cross a 64K boundary
82 * and must be dword aligned
83 * ICH2 spec c #24 - UDMA mode 4,5 t85/86 should be 6ns not 3.3
85 * Should have been BIOS fixed:
86 * 450NX: errata #19 - DMA hangs on old 450NX
87 * 450NX: errata #20 - DMA hangs on old 450NX
88 * 450NX: errata #25 - Corruption with DMA on old 450NX
89 * ICH3 errata #15 - IDE deadlock under high load
90 * (BIOS must set dev 31 fn 0 bit 23)
91 * ICH3 errata #18 - Don't use native mode
