That's the problem, you cannot easily verify it. There are no indicator leds on the usb device or the host port that could tell you when the device is used in usb 2.0 or usb 1.x mode. And the BIOS doesn't report if it is using usb 2.0 or 1.x protocol mode. I think you have to use an USB protocol analyzer device to really find out what's happening at boot time when the BIOS reads from the mass storage device. I suspect that when you test a few other systems with the same "CHIPSBNK USB 2.0" usb flash memory device, you'll find a few that are able to boot *much* faster ... -- This message posted from opensolaris.org
