I have my internal IDE DVD burner attached to a USB2IDE adaptor so it appears as a USB2 device. It appears as a USB2 High-Speed device to the BIOS and XP. The Acronis recovery CD boots OK but when I select the option for the FULL mode I get a blank screen after the Acronis logo screen appears. However I can get into TI if I use SAFE mode. I realize my setup is a bit unusual but I was wondering if a more conventional USB2 external reader/burner would work in FULL mode. Has anyone booted TI in FULL mode from an External USB2 CD/DVD drive? Just curious. btw, tried this with 2337 and previous versions. All failed to come up in FULL mode.
