First, did you uninstall PROSet and run the bat file to install the driver used by the utility?
I am asking because the utility and PROSet use a driver that could cause problems if the driver version does not match. That is the reason why the readmefirst.txt says to uninstall PROSet before installing the uitlity.
I am guessing you probably did the installation, but I wanted to verify that you did it. One caveat, if you run the install from command prompt without admin rights, the driver file will not get copied. Then you could be using the wrong driver.
Second, the restoreimage option only works to restore a previously saved image that is in the NIC format. That option does not work with the flb file. The command to use would be BOOTUTILW64E.EXE -nic 1 -up=pxe -file=bootimg.flb. The example used pxe, but you could substitute another image type such as iSCSI or efi64 if that is the image you were trying to install or upgrade.
Third, since the version is showing up as unknown, I suspect that the flash is disabled on the adapter. Try this command to enable the flash: BOOTUTILW64E.EXE -nic 1 -FE
If none of the above works, make sure you using the contents of the latest webpack labeled version 17.1. I can recall having some issues when using the earilier versions.
Another thing you could try if nonthing else works.Create a boot dos device and use the dos version of the utility.
I hope something above helps.Let me know what you find.
