Hello Folks:

I have a MSI-1710A ("Megabook") which is Athlon X2 Turon based
notebook (4GB RAM,

Anyway during a 7.0-RELEASE-amd64 boot up I see:

After looking at my ASL code, I noticed that YES this code was
generated by the MSFT devkit which means its probably NOT spec
compliant.

RSDT: Length=64, Revision=1, Checksum=83,
        OEMID=MSI_NB, OEM Table ID=MEGABOOK, OEM Revision=0x7000725,
        Creator ID=MSFT, Creator Revision=0x97
        Entries={ 0xcffc0200, 0xcffc0390, 0xcffc03f0, 0xcffc0430,
0xcffce040, 0xcffc42f0, 0xcffc4330 }

The pertinent section (DSDT) condensed is:

_SB.PCI0.SBRG:

Device (EC) {
      Device (BAT1) {
            Name (_HID, EisaId ("PNP0C0A"))
            Name (_UID, One)
            Name (_PCL, Package (0x01)
            {
                  _SB
            })
            Method (_STA, 0, NotSerialized)
            {
               If (MYEC)
               {
                  If (MBTS)
                  {
                      Return (0x1F)
                  }
                  Else
                  {
                      Return (0x0F)
                  }
               }
               Else
               {
                      Return (0x0F)
               }
        }
}

I've read http://www.freebsd.org/doc/en/books/handbook/acpi-debug.html
which is very helpful.  In any event should I attempt to try to
rewrite my ASL to make it more spec conforming so Intel's CA likes it
OR would it be better to try to work around it in the CA directly.  I
believe I understand the problem but I'm still reading the spec
regarding embedded controller sections (which is a little different).

I believe I'm probably not the only MSI FreeBSD owner so I figured I
would share!

Thanks a lot!
