700 | * | |
701 | * When there's no device attached to the first downstream port of the | |

703 | * configure the 4726. However, ATA emulation of the device is very | |
704 | * lame. It doesn't send signature D2H Reg FIS after the initial | |
705 | * hardreset, pukes on SRST w/ PMP==0 and has bunch of other issues. | |
