Hi all from hot Athens I have the possibility to update the Firmware of my HP35665A with the 2 floppy discs (HP NOS) from the existing A.01.00 FW to the last one A.01.08. A friend tells me not to attempt the update because if in the floppy(produced 1993) there is some mistake, after so many years, I will have a big problem. Another friend says that when the existing inside drive of the analyzer encounters a file with problem it stops before installing an incorrect FW file Practically, he says, that somewhere in the analyzer there is a check sum file that checks the integrity and avoids errors during the update and stops the procedure. I cant decide what to do any help is well come Any experience about all this?? Some one did the update? Thanks George PS.Attached files of one of the two floppy's |

Maybe the thing to do is buy yourself a USB floppy drive and clone the original. This will also let you know if any sectors are unreadable. Maybe save an image of it for posterity. |

Thank you bson I already have a USB floppy drive but cant read those files (.Lif). But even if it could do it would also clone a "wrong" file if there were. I'm not much expert in computers, but I think I should, somehow, do the "check sum" all the files in the 2 floppy discs . But how can I do it???? |

Hmm, I have A.01.00 as well. Is there a list of changes and/or fixes in the newer versions? |

There are a few utilities out there to read lif floppies from a PC. Not all work and they can be picky on OS/floppy type etc. "lif2dos" is one of them. I have backed up the files on a lif floppy before using a PC - it would be good to ensure you can read all files on both floppies. The last lif floppies I backed up were from 91 and I was able to read all of the files successfully. |
