Is there any way to reserve specific ATA channel numbers for specific
PCI ATA controllers?
During bootstrap my kernel says:
atapci0: <ITE 8212 ATA/RAID controller> port 0x8800-0x880f,
0x8400-0x8403,0x8010-0x8017,0x7c00-0x7c03,0x7810-0x7817
irq 16 at device 12.0 on pci3
ata2: at 0x7810 on atapci0
ata3: at 0x8010 on atapci0
atapci1: <Intel ICH5 ATA100 controller> port 0xf000-0xf00f,0-0x3,
0-0x7,0-0x3,0-0x7 irq 9 at device 31.1 on pci0
ata0: at 0x1f0 irq 14 on atapci1
ata1: at 0x170 irq 15 on atapci1
atapci2: <Intel ICH5 SATA150 controller> port 0xd000-0xd00f,
0xcc00-0xcc03,0xc800-0xc807,0xc400-0xc403,0xc000-0xc007
irq 9 at device 31.2 on pci0
ata4: at 0xc000 on atapci2
ata5: at 0xc800 on atapci2
The relevant part of my kernel configuration file currently says:
# ATA and ATAPI devices
device ata0 at isa? port IO_WD1 irq 14
device ata1 at isa? port IO_WD2 irq 15
device ata
device atadisk # ATA disk drives
...
options ATA_STATIC_ID #Static device numbering
I want the ICH5 SATA150 channels to be ata2 and ata3.
Thanks,
