The BIOS release bit. This bit is used by the BIOS software to raise an event to the
ACPI software. The ACPI software has a corresponding enable and status bit to
control its ability to receive the ACPI event. Setting BIOS_RLS sets GBL_STS, and it
generates an
this bit and also sets the BM_STS bit. Writing a 0 has no effect. This bit is cleared by
writing a 1 to the GBL_STS bit.
This bit is used to set the BM_STS bit and if the BM_RLD bit is also set, then an SCI
interrupt is generated. Writing a 1 sets BM_CNTRL to 1 and also sets BM_STS.
Writing a 0 has no effect. Writing a 1 to BM_STS clears BM_STS and also clears
BM_CNTRL.
