since I am not familiar with your machine I didn't have this information..This should work on your e-sata/USB 2.o port. Plug USB flash drive into that port
I would just copy that file you ask to dl in the root in the usb and the comp would detected when is connected to the comp. but for some reason i'm not able to see the usb where I can see that file that I need to use
the iso is installed in a 4gb usb while i just copy the program (driver) in a 16 gb different from the usb that has the iso installed.
ok put the 4gb USB flash drive into e-sata/ USB 2.0 combined port and boot... you should not need other USB flash drive if you are using combined port.
