    Hi,

    I have a couple of flashdrives that i've formatted as bootable DOS disks and i've used both of them on my old HP NC6400 for yrs. But my new T400s is pretending that it can't see them. My T400s will boot from an external USB floppy and it also has an entry in the boot sequence list in the BIOS for an external USB HD and, IIRC, an external USB optical drive. But formatting my flashdrive to emulate a HD hasn't worked so far on the T400s.

    If I plug in one of these DOS flashdrives, hit the power button and then F12 the "bootable devices currently seen" list shows NO USB devices at all.

    So before I call Lenovo tech support I thought i'd check and see what your experience has been. And, if you have successfully used one of these guys on your T400s what utility did you use to format your drive and what kind of emulation did you use?

    TIA,
    laffin_boy

    One thing too try and it probably wont work, is to plug in the USB drive after the machine is booted.

    Oops, another thing to try is this MS Technet forum:

    There might be a option in the t400s for legacy usb support. I use that option to boot a usb drive on a laptop that did not recognized usb drive.
