USB Provisioning -- a Few Insights to Help Out
When provisioning Intel® vPro™ processor technology systems via One Touch -- using a USB flash drive -- the following tips and information may be of interest.
- Only FAT16 format supported
- Setup.bin file must be first file, at the root of the drive
- Insert the USB flash drive before booting the system (detection happens during POST)
- Provisioning records include the PID (provisioning ID), PPS (provisioning passphrase), default admin password, and new admin password
- Only systems with Intel® AMT in factory default mode will respond to USB provisioning. Once USB or One Touch provisioning are performed on a system – only a full BIOS reset will allow this option again.
- Once the provisioning keys and setup information is transferred – Intel® AMT is now in "setup" mode and the Setup.bin file is incremented to the next valid key.
- In ad-hoc tests, 20,000 provisioning records used 10MB of space on the USB flash drive. Most favorable experiences occur with flash drives that are 2GB or smaller.
- With a larger number of provisioning records, the One Touch process may experience a delay as the setup.bin file is parsed to find the next valid record. In ad-hoc tests, 1000 records on the key experienced a 15 second delay, 100,000 keys experienced a 3 minute delay.
- Once Intel® AMT is in setup mode, "hello" packets will be initiated. The interval for sending packets will increase over time until the "ProvisionServer" accepts and responds. The intervals are as follows: 5 retries per minute, 5 retries per every 10 minutes, 5 retries every hour, etc. Eventually it may appear that no "hello" packets are being sent. The intervals are reset if the power is removed from the system.
