>Description:
Running FreeBSD 7.0-STABLE (csup today) on AMD64.

I got a MSI K9AGM3-F motherboard, with ATI SB600 chipset. The PATA controler is well recognised as <ATI IXP600 UDMA133 controller>, but the sata controler is detected as <ATI (ID=43801002) AHCI controller> : 

The SATA controller is setup in AHCI mode on the BIOS.

(output from dmesg : ) 
atapci0: <ATI (ID=43801002) AHCI controller> port 0xb000-0xb007,0xa000-0xa003,0x9000-0x9007,0x8000-0x8003,0x7000-0x700f mem 0xfe7ff800-0xfe7ffbff irq 22 at device 18.0 on pci0
atapci0: Reserved 0x10 bytes for rid 0x20 type 4 at 0x7000
atapci0: Reserved 0x400 bytes for rid 0x24 type 3 at 0xfe7ff800
ioapic0: routing intpin 22 (PCI IRQ 22) to vector 49
atapci0: [MPSAFE]
atapci0: [ITHREAD]
atapci0: AHCI Version 01.10 controller with 4 ports detected

atacontrol list returns the following : 
[carenath] ~# atacontrol list
ATA channel 0:
    Master:  ad0 <Maxtor 6Y120L0/YAR41BW0> ATA/ATAPI revision 7
    Slave:       no device present
atacontrol: ioctl(IOCATADEVICES): Device not configured

The 4 drives are still recognised and work perfectly.


>How-To-Repeat:
Run the "atacontrol list" command.
