Not sure why you are getting an error, but I can confirm this mod worked for me on 3 nx7300 machines.
ayhanrv: I have the same output with my nx7300 ... has anyone found a solution yet ? I tried the HP moded SLIC2.1 BIOS for HP Compaq nx7300 Notebook PC (sp40745_MOD.zip) also with no luck. It still reads SLIC 2.0 !! Any suggestions plz .. ?
