Unable to boot from external USB DVD drive

[Matthew Dillon]

:Im trying to boot DragonFly live cd(latest build) from an external USB dvd
:drive. But Im unable to get past the mountroot prompt. I have a PS/2
:keyboard connected to it, but whats weird too is that the keyboard doesnt
:work in the mountroot prompt. I tried booting without ACPI and also
:without AHCI but I cannot get any further.
:
:This box is a HP Proliant DL180 G5. It came without an internal CD/DVD
:drive (which we are still waiting to get).
:
:FreeBSD 7 installer loads fine on this box.
:
:Any ideas?
:Petr

    Hmm.  It sounds like the kernel might not be able to attach
    the USB dvd drive on boot.

    Try plugging the USB dvd drive into a different usb port.

    I don't know whats up with the keyboard.  Usually ps/2 keyboards
    work fine and usb keyboards have problems.
