SubjectRe: PDC20268 UDMA troubles
Andre,

Thank you for the reply.

I was wondering if both controllers (PDC20268 and PDC20267) should show up
when I cat /proc/ide/pdc202xx ?

I'm not disabling the BURST_BIT, I think the driver is, but only on the
second card. Thus, I can't get udma5 on all 4 chains.

This is from dmesg:

PDC20267: IDE controller on PCI bus 00 dev 40
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode.
ide2: BM-DMA at 0x1080-0x1087, BIOS settings: hde:DMA, hdf:pio
ide3: BM-DMA at 0x1088-0x108f, BIOS settings: hdg:DMA, hdh:pio
PDC20268: IDE controller on PCI bus 00 dev 50
PDC20268: chipset revision 2
PDC20268: not 100% native mode: will probe irqs later
PDC20268: (U)DMA Burst Bit DISABLED Primary MASTER Mode Secondary MASTER
Mode.
ide4: BM-DMA at 0x10d0-0x10d7, BIOS settings: hdi:pio, hdj:pio
ide5: BM-DMA at 0x10d8-0x10df, BIOS settings: hdk:pio, hdl:pio

Let me know if you need more information.

cheers,
