Jeff, I tried moving to ATA driver for PIIX4 today and found ATA need to
request
2 IRQ lines, each one of them belongs to primary and secondary channel.
However,
when I make PIIX4 worked under IDE driver, it also need to request one
IRQ for "ide1".
So it's necessary to disable secondary channel manually?
Another question is my PIIX4 chip has device ID + vendor ID of
0x71108086. But it finally
was mapped to following ID of piix_pci_tbl[] array. Device of 0x7110 and
0x7010 should
be quit different, right?
{ 0x8086, 0x7010, PCI_ANY_ID, PCI_ANY_ID, 0, 0, piix_pata_mwdma },
Gavin
