on my system (7.0-CURRENT as of 7/24 18:42 EST) I receive following
message during boot:
ad0: DMA limited to UDMA33, device found non-ATA66 cable
ad0: 28615MB <IC25N030ATMR04 0 MOAOAD0A> at ata0-master UDMA33
Since there is no cable (drive attached directly to the connector
mounted on the piece of PCB), I wonder whether there are any overriding
knobs. ATA controller is VIA8235:
atapci0: <VIA 8235 UDMA133 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xfc00-0xfc0f at device 17.1 on pci0
atapci0 at pci0:17:1: class=0x01018a card=0x120514ff chip=0x05711106
vendor = 'VIA Technologies Inc'
device = 'VT82xxxx EIDE Controller (All VIA Chipsets)'
class = mass storage
subclass = ATA
According to the data sheet drive is capable of UDMA100.
Any suggestions will be greatly appreciated.
