Recently, I upgraded the disk in my Toshiba A105 with a 7200rpm SATA-II
device but it seems to still talking at SATA-I speed :-(

atapci0: <Intel ICH7M SATA300 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x18b0-0x18bf at device 31.2 on pci0

acd0: DVDR <MATSHITADVD-RAM UJ-841S/1.60> at ata1-master UDMA33

There don't appear to be any obvious 'compatibility jumpers' on the
drive, so I'm wondering what gives?

Is it possible this is hard-coded into the BIOS?
