USB stick not recognised in one-time bootmenu D90D7
Hello everybody 
,
Today I was trying to pull the firmware of the D90D7 with a USB stick, configured with the "Wyse USB Firmware Tool", but my USB stick was not recognised in the one-time boot menu.
So I went into the BIOS and there I saw an option called "Boot from USB", which is "disabled". You have change this setting to "enabled". Restart your machine and go to one-time bootmenu by pressing "p" during boot.
Hopefully this helped some of you guys
