When entering the BIOS setup page, press “A”

When entering the BIOS setup page, press “A” key to activate the advanced configuration mode.

Let’s take HP Pavilion dm3 for example.
1. Press F10 when the system is booting (Press F10 key to enter the BIOS setup windows on all HP platforms).
2. When it shows “entering the BIOS setup”, press “A” key before the BIOS setup window appears.
You should be agile when doing this.

On Pavilion DV6 laptop you may press [ESC] then [F10] key, and when entering to BIOS Setup, hold [A] key.
You'll heard some *beeps* for 25 seconds, but seen all BIOS settings!
