Hi,
I've got an ASUS P5GD1 [1] Motherboard, with a 915P chipset and a
ICH6R [2] southbridge.
Since the UDMA controller was recognized as an "GENERIC ATA
controller", I was stuck in UDMA33 mode for my Seagate Ultra ATA/100
IDE hard drive, and I wasn't able to change the settings using
"atacontrol mode". Since there is already a great list of Intel
supported chipsets in src/sys/dev/ata/ata-chipset.c, I've added the
references of the chip in ata-chipset.c and ata-pci.h, on a fresh
cvsuped 6.0-CURRENT.
Please, someone could review it ? My first patch :/
pciconf -lv give the following output for this chip :
atapci0@pci0:31:1: class=0x01018a card=0x26408086 chip=0x266f8086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82801FB ICH6 Ultra ATA Storage Controller'
class = mass storage
subclass = ATA
The Intel's datasheet is speaking of this chip as :
Integrated IDE Controller
-- Independent timing of up to two drives
-- Ultra ATA/100/66/33, BMIDE and PIO modes
-- Tri-state modes to enable swap bay
So, it doesn't seem to be really different from other Intel IDE controllers.
My two-lines patch :

Now, when the kernel is loading, the controller is recognized (output
of dmesg) :
atapci0: <Intel ICH6 UDMA100 controller> port
0xffa0-0xffaf,0x376,0x170-0x177,0x3f
6,0x1f0-0x1f7 at device 31.1 on pci0
ata0: channel #0 on atapci0
ata1: channel #1 on atapci0
And my hard drive works like a charm :
ad0: 38166MB <ST340014A/3.04> [77545/16/63] at ata0-master UDMA100
Note that there is always, on that board, another driver spotted as
"GENERIC", for this chip :
atapci1@pci0:31:2: class=0x01018f card=0x26011043 chip=0x26528086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82801FR/FRW ICH6R/ICH6RW SATA Controller'
class = mass storage
subclass = ATA
I'll try to add it, as soon I will have a SATA-compliant drive to test it :-)
