/KEEPCONFIG : Ensures configuration words are preserved during an upgrade process.
Updating NVM is a low-level operation. Improper use can render the network adapter unusable.
: Modifying the EEPROM typically breaks the hardware's internal validation structure. EEUPDATE automatically calculates and applies the correct EEPROM checksums and CRCs upon asset modification. eeupdate-5.35.12.0.zip
eeupdate /NIC=1 /MAC=001122334455 Overwrites the permanent hardware MAC address of the specified adapter.
Modifying a network adapter’s EEPROM to change a burned-in MAC address may violate local telecommunications laws if used to impersonate another device. In many jurisdictions, the original IEEE-assigned MAC is considered a permanent identifier. Use this tool only for legitimate repairs or authorized hardware modifications. : Modifying the EEPROM typically breaks the hardware's
