It is for OEM pre install Windows and no need to Active , If you select Non OS , then you
need to Active your OS before you use .
Function Detail :
7. UUID :
Total is 16 byte data , Front 10 byte is time random data , last 6 byte is LAN MAC .
8. Brightness Table :
It depend on LCD EDID to set different brightness data .
9. HDD Numbers Flag :
[1]Single [2]Two , BIOS check this flag to set setup menu is RAID or AHCI mode .
a. SLP2.0 Build Sig :
[1]Non OS : EEPROM fill ”MS” for non Microsoft OS , BIOS not load SLP OPROM function .
[2]OS : EEPROM fill Others for Microsoft OS , BIOS load SLP OPROM function .
b. Wireless LAN ID :
If change M/B , but wireless/B not change , need fill wireless MAC into new change M/B .
c. AC Adapter Select :
[1]45W : Machine need 45W AC Adapter .
[2]65W : Machine need 65W AC Adapter .

[4]90W : Machine need 90W AC Adapter .
[5]120W : Machine need 120W AC Adapter .
[6]180W : Machine need 180W AC Adapter .
The AC Adapter request is base on machine power request , some high performance need
120W Adapter , low cost machine maybe only 75W can meet request .
Because AC Adapter do not had HWID for detect , so need key in data by menu .
(1) If machine setting 75W , AC Adapter use 120W , it‟s OK .
(2) If machine setting 120W , AC Adapter use 75W , because Adapter can‟t support
enough power , it can‟t charge well .
(3) If machine setting 90W , AC adapter use 90W , Adapter Select 90 W , it‟s OK .
(4) If machine setting 90W , AC adapter use 90W , Adapter Select 120W , “PHM” and
“ECO” utility will display wrong data , power consumption display double data more
the machine actual use .
