Hello.
I've got a box with a VIA VT8251 chipset and a single SATA HD, running
6.3/i386.
I'm trying to upgrade it to 7.2, but, when booting with the new kernel,
it won't detect any HD.
In my BIOS I can set the controller to SATA, RAID or AHCI, but that
doesn't matter.
Here's what I see when booting 6.3:
atapci0: <VIA AHCI controller> port
0xe880-0xe887,0xe800-0xe803,0xe480-0xe487,0xe400-0xe403,0xe080-0xe08f
mem 0xfebfec00-0xfebfefff irq 21 at device 15.0 on pci0
atapci0: AHCI Version 01.00 controller with 4 ports detected
ata2: <ATA channel 0> on atapci0
ata3: <ATA channel 1> on atapci0
ata4: <ATA channel 2> on atapci0
ata5: <ATA channel 3> on atapci0
atapci1: <VIA 8251 UDMA133 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xfc00-0xfc0f at device 15.1 on pci0
ata0: <ATA channel 0> on atapci1
ata1: <ATA channel 1> on atapci1
...
ad4: 152627MB <WDC WD1600AAJS-00PSA0 05.06H05> at ata2-master SATA300
Trying to mount root from ufs:/dev/ad4s1a
On 7.2 the output is roughly the same (I couldn't save it), but it won't
find ad4 and prompt me for a boot device (with none available).
Here's an extract from "pciconf -lv":
atapci0@pci0:15:0: class=0x010601 card=0x33491106 chip=0x33491106
rev=0x00 hdr=0x00
vendor = 'VIA Technologies Inc'
device = 'VT8251 VIA VT8251 AHCI RAID Controller'
class = mass storage
atapci1@pci0:15:1: class=0x01018a card=0x05711106 chip=0x05711106
rev=0x07 hdr=0x00
vendor = 'VIA Technologies Inc'
device = 'VT82C586A/B/VT82C686/A/B/VT823x/A/C Bus Master IDE
Controller'
class = mass storage
subclass = ATA
Please help.
bye & Thanks
