24 ------- Quanta describes their release sequence:
26 Let me explain our ISO sequence: Qxxxx First x: 1 for A test, 2 for B test, 3 for C test Second x: A~Z: milestone Third x: 1~9: change when test team release to customer, manufacture (outside R&D) Forth x: 1~9: change when sw team release to test team.(inside R&D)
28 Take EC as example: Q1A11 when sw team release to test team. Test team find some problems, can not relase out Q1A12 when sw team fix the problem and release to test team again Test team test OK, and release out
30 Next version sw team release will be Q1A21
32 As I mentioned we will use file name to distinguish the release.
34 EC release will be PQ1A21.bin (Leading by P) BIOS release will be BQ2A11.bin (leading by B)
