I got a notebook floppy drive connected to CN15, but it wouldn't boot. It did init on boot up and the floppy led came on briefly as the unit booted.
Using the adapter made for the VGA out on the i-Opener, the monitor came out of sleep mode as the GTC booted, but displayed no image.
Most likely again, access to the setup in bios is needed to either enable the floppy or set it to be a boot device and enable dual display on both the monitor and LCD. I tested the floppy pinouts against documentation from Teac (The floppy drive is Teac drive from a Thinkpad) and the documentation from Kray's Webplayer website.
I also checked for 5 volts on CN3 and CN5, both had 5 volts, the same as the VGA out and COM2 on the i-Opener
Pin 6 on CN3 was 5volt (VGA Out?)
Pin 10 on CN5 was 5volt (COM2?)
Anyone have any progress getting into the bios setup yet?
