Problem with nvram backup utility for integrity servers

[Yair Zaretski]

hello,

i've recently installed this utility and worked with it fine for half a day, and then suddenly every command i try to run i get this error message:
fs0:\> nvrambkp.efi -h
'nvrambkp.efi' not found
Exit status code: Invalid Parameter

output of ls command show the following:
fs0:\> ls
Directory of: fs0:\

08/23/06 09:49a 4,096 EFI
08/23/06 09:49a 296 STARTUP.NSH

08/27/06 12:41p 3,660 nvrestore.log
5 File(s) 18,477 bytes
1 Dir(s)

tried to re-run efi shell and restart the system but to no avail.
does anybody have an idea except re-installing the utility?

Looks like the nvrambkp.efi command is in the EFI sub-directory.

Try

cd EFI first
then execute nvramnkp.efi -h
