I have a ProLiant DL380p G8 server not connected to the network. It is powered up and connected via a KVM to a keyboard and Monitor. It is booting into ESXi 4.1 via a USB drive inserted into the internal USB port. I have the ESXi 4.1 U3 patch on another USB drive. Can patch the internal ESXi 4.1 USB drive via the external USB port with the patch on the second USB drive?
