(CONFIG_ATA) > 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 },
