You should use the command "mount /dev/hda1 /mnt" (no trailing slash after hda1). On my box the CF is hda, not hdc... but if for some reason yours is hdc, then use that. And I assume "legato.lic" and "/devf/" are just typos in your reply (should be "elgato.lic" and "/dev/" respectively). Pat |

Yep the fat finger of fate struck. What are the commands to copy the license file to the CF card and then the modified file back? I think my CF card is hda1. Here is what I get with a df -h command: [root@E749xx /]$df -h Filesystem Size Used Available Use% Mounted on rootfs 7.7M 6.1M 1.2M 83% / /dev/root 7.7M 6.1M 1.2M 83% / /dev/mtdb3 60.0M 21.6M 38.4M 36% /flash But none of these is the CF card inserted, since it is a 500 MB card. Not sure what the disks listed are. If I press the Media Manager button from System, it shows the CF card format button highlighted indicating it is recognized by the system. |

This is where the binary patching happens. * /flash/egServer/license/elgato.lic is the file where the license information is stored. * * /flash/linux are all of the extra files that Agilent includes, on top of BusyBox (which is a barebones set of Linux commands). [2] As far as the elgato file goes, the following sha256 hashes should tell you if you have the same file or not. Copied from sha256sum command[c]: * 8f4bfc453ed7aa871bba7ea2301bb29280466c36f78f703302b5348ec44612f0 elgato.original * 5a857ab04ce60f4a149682299bbd860649f36478e29e4693870a8624a4eafad7 elgato.nokeys * ec57d11b6151795ba2c6f6979cb789622dc24c263fef70ca4791780f4525e771 elgato (nokeys and clock patch) Tips: df reports results for each mounted disk. Until you do something with the GUI that will cause a write to the disk (try to save file, save data, or format PCMCIA), the unit won't even mount it. You can manually mount the disk, in its proper location, by typing: mount /dev/hda1 /flash/mnt/pcmcia Then, you can browse to /flash/mnt/pcmcia to read (or copy) files you stored on the device. Picture and data saves will now also work (assuming the device can read your partition). [a]: Again, for me, I formatted it as ext3. You can use fat16, I think. I am not sure about fat32. [2]: Notice they have their own copy of ps, grep. They also have some custom scripts like elgatosleep, diagServer, enable_matrix_kb. And then some are just configuration files, like the files in /etc. do "find ." in /flash/linux to see this stuff. [c]: Since sha256sum isn't included in BusyBox or agilent's files, then you'll have to do this on your desktop or whatever. |

I edited the license file with VI and now have all options. Still not clear on how to copy a file to the CF card but will pursue it. Thanks for the help. So now my E7495A has a green GPS indicator and all options. |

You can use the built in menu to add licenses, just use anything you like for the license key. |
