* Documentation

|
|
* PIIX4. Older device documentation is now a bit tricky to find.
|
|
*
|
|
* Errata of note:
|
|
*
|
|
* Unfixable
|
|
* PIIX4 errata #9 - Only on ultra obscure hw
|
|
* ICH3 errata #13 - Not observed to affect real hw
|
|
* by Intel
|
|
*
|
|
* Things we must deal with
|
|
* PIIX4 errata #10 - BM IDE hang with non UDMA
|
|
* (must stop/start dma to recover)
|
|
* 440MX errata #15 - As PIIX4 errata #10
|
|
* PIIX4 errata #15 - Must not read control registers
|
|
* during a PIO transfer
|
|
* 440MX errata #13 - As PIIX4 errata #15
|
|
* ICH2 errata #21 - DMA mode 0 doesn't work right
|
|
* ICH0/1 errata #55 - As ICH2 errata #21
|
|
* ICH2 spec c #9 - Extra operations needed to handle
|
|
* drive hotswap [NOT YET SUPPORTED]
|
|
* ICH2 spec c #20 - IDE PRD must not cross a 64K boundary
|
|
* and must be dword aligned
|
|
* ICH2 spec c #24 - UDMA mode 4,5 t85/86 should be 6ns not 3.3
|
|
*
|
|
* Should have been BIOS fixed:
|
|
* 450NX: errata #19 - DMA hangs on old 450NX
|
|
* 450NX: errata #20 - DMA hangs on old 450NX
|
|
* 450NX: errata #25 - Corruption with DMA on old 450NX
|
|
* ICH3 errata #15 - IDE deadlock under high load
|
|
* (BIOS must set dev 31 fn 0 bit 23)
|
|
* ICH3 errata #18 - Don't use native mode
