--- Quote from: Hamster on May 24, 2021, 09:18:50 pm --- So its just a mater of figure out the feature codes.. I am assume the 16911 32M feature key is: 16911_32Meg_Samples --- End quote --- Here is the list of 16910 / 16911 feature names in the 3rd column below: --- Code: ---'16910A-256' HW 16910_256K_Samples : Acquisition memory depth of 256K # Node Locked '16910A-001' HW 16910_1Meg_Samples : Increase acquisition memory depth to 1M # Node Locked '16910A-004' HW 16910_4Meg_Samples : Increase acquisition memory depth to 4M # Node Locked '16910A-016' HW 16910_16Meg_Samples : Increase acquisition memory depth to 16M # Node Locked '16910A-032' HW 16910_32Meg_Samples : Increase acquisition memory depth to 32M # Node Locked '16910A-250' HW 16910_250MHz_State : Maximum state speed of 250 MHz # Node Locked '16910A-500' HW 16910_500MHz_Turbo_State : Increase maximum state speed to 500 MHz # Node Locked '16911A-256' HW 16911_256K_Samples : Acquisition memory depth of 256K # Node Locked '16911A-001' HW 16911_1Meg_Samples : Increase acquisition memory depth to 1M # Node Locked '16911A-004' HW 16911_4Meg_Samples : Increase acquisition memory depth to 4M # Node Locked '16911A-016' HW 16911_16Meg_Samples : Increase acquisition memory depth to 16M # Node Locked '16911A-032' HW 16911_32Meg_Samples : Increase acquisition memory depth to 32M # Node Locked '16911A-250' HW 16911_250MHz_State : Maximum state speed of 250 MHz # Node Locked '16911A-500' HW 16911_500MHz_Turbo_State : Increase maximum state speed to 500 MHz --- End code --- |

So, I was able to upgrade my 4Ms card to 32Ms , i am unable to sort the 500Mhz Turbo mode out. --- Code: ---EEPROM DATA: Serial @ 0000-0009 Unknown 000A 0x00 ( changing to 0x01 results in invalid ) Memory @ 000B 0x00 = 256K ( assumed ) 0x01 = 1M ( assumed ) 0x02 = 4M/250 ( confirmed ) 0x03 = 16M/250 ( confirmed ) 0x04 = 32M/250 ( confirmed 0x05 = 256k/250 ( confirmed, probably invalid ) 0x06 = 256k/250 ( confirmed ) -- I assume any value over 0x04 is treated as 0x00 0x14 = 256k/250 ( confirmed ) Unknown @ 000C 0x16 -- Changing to 0x17 flagged invalid -- Changing to 0x32 ( and adding 0x16 to checksum ) - invalid CheckSum @ 000D Incrementing a value @ 0B , increment Checksum. Same goes for incrementing serial # --- End code --- For example, 0x0A-0x0D 0x00 0x00 0x16 0x27 = 256K [ assumed ] * not tested 0x00 0x01 0x16 0x28 = 1Ms [ assumed ] * not tested 0x00 0x02 0x16 0x29 = 4Ms 0x00 0x03 0x16 0x2A = 16Ms 0x00 0x04 0x16 0x2B = 32Ms |

Maybe you can apply a 16911_500MHz_Turbo_State feature upgrade using a license file and dump the eeprom before and after to see what changes. |

i just need to figure out how to generate a lic file, the agHwUpgrade program will read the lic and apply it, just need to figure out how to sign it. it would look like this: #START LICENSE INFO FEATURE 16911_500MHz_State agilent 1.0 permanent uncounted HOSTID=ANY SN=?????????? SIGN=???????????? #END LICENSE INFO if someone has a 500Mhz key for another Serial #, i could change my Serial # to match and apply the license to it. |

the good thing is the card i am using is bad ( PSync Issue, and Bad Memory Bus address ) , so its just a parts board for testing , just have to reboot the LA every time on a Chip contents change. |
