Hello, I had flash a bios which disable CFG Lock, but which made boot hang.

I found that some bios have the same issues, such as (RTC Fix).
Because they have difference RTC Device after update bios, they can store one in STAT.
Which like this.....
Code:
DefinitionBlock ("", "SSDT", 1, "HACK", "SET-STAS", 0x00000000)
{
    External (_SB_.PC00.LPC0, DeviceObj)    // (from opcode)
    External (_SB_.PC00.LPC0.RTC_, DeviceObj)    // (from opcode)
    External (STAS, IntObj)    // (from opcode)

    Scope (_SB.PC00.LPC0)
    {
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            Store (One, STAS)
        }
    }

    Scope (_SB.PC00.LPC0.RTC)
    {
        Method (_STA, 0, NotSerialized)  // _STA: Status
        {
            If (LEqual (STAS, One))
            {
                Return (0x0F)
            }
            Else
            {
                Return (Zero)
            }
        }
    }
}

It seems that RTC had no difference after update bios, but there are some odd changes which beyond my head.

Any ideas?
Any help will apprecite!!!
