Perform step 103；
Step 102, linux system is launched into, detects whether current PEX9797EEPROM is latest edition, if then holding
Row step 103, otherwise updates PEX9797EEPROM according to prompting step；
Step 103, existing EEPROM is kept.
Wherein, the PEX9797 is the PEX9797 of specific I2C addresses on mainboard.
Wherein, the prompting step of step 102 is specially：PEX9797 chips are set up with updating the communication in source by I2C, under
Newest PEX9797EEPROM is carried, old version is replaced with into new version preserves.
Wherein, the target machine is applied to English telecommunications services device.
In addition, the present invention also provides the device that a kind of PEX9797 chips update EEPROM, described device includes：
Monitoring modular, for having monitored whether more new command in real time after target machine start, update module of being set out if having
Update, if keeping existing EEPROM without if；
Update module, for launching into linux system, detects whether current PEX9797EEPROM is latest edition, if
Step 103 is then performed, otherwise PEX9797EEPROM is updated according to prompting step.
Wherein, the PEX9797 is the PEX9797 of specific I2C addresses on mainboard.
Wherein, the prompting step of the update module is specially：PEX9797 chips are set up with updating the logical of source by I2C
Letter, downloads newest PEX9797EEPROM, and old version is replaced with into new version preserves.
Wherein, the target machine is applied to English telecommunications services device.
The present invention proposes that a kind of PEX9797 chips update EEPROM method and device, and it implements process and is：Start
Machine with PEX9797 chips enters linux system, when user has demand to update PEX9797 use environments, it is necessary to
PEX9797 EEPROM is updated to coordinate.Realized using the I2C instruments matched with start machine with interior renewal 9797EEPROM.
PEX9797I2C boxes must be used to update FW or hardware before being solved using such a method must pull down chip and use burning
Record device could update FW limitation, and substantially increasing efficiency reduces cost, configures 9797EEPROM more easily and fast, simply,
Perfect existing technological deficiency, realizes the online updating of PEX9797 chips.
