Strangely enough to mine and I'm sure many other peoples surprise, the commands are no longer in BIOS. See below.
HKEY_USERS\.DEFAULT\Control Panel\Keyboard and HKEY_CURRENT_USER\Control Panel\Keyboard
0 - Turn all indicators Off (NumLock, CapsLock, ScrollLock)
1 - Turn CapsLock On
2 - Turn NumLock On
3 - Turn CapsLock and NumLock On
4 - Turn ScrollLock On
5 - Turn CapsLock and ScrollLock On
6 - Turn NumLock and ScrollLock On
7 - Turn all indicators On (NumLock, CapsLock, ScrollLock)
In my case, the string value was some 7 or 8 digit number such as 21765430. These entries are the cause of the reboot change in the num lock status. If you want it on when you boot, set the string value to 2 in all the keys with numeric values. Problem solved!
