Function 0 Register A2 - non-software SMI# status register
(documented by Miran Grca):
(documented by Miran Grca):
Bit 4: I set, graphics card goes into sleep mode
This register is most likely R/WC
Function 0 Register A3 (added more details by Miran Grca):
Bit 7: Unlock SMM
Bit 6: Software SMI trigger (also doubles as software SMI# status register,
cleared by writing a 0 to it - see the handler used by Phoenix BIOS'es):
If Function 0 Register 46 Bit 6 is set, it raises the specified IRQ (15
or 10) instead.
