From datasheet ICH3M, according to PMBASE:
31:16 --  reserved
15:7   --  Base address
6:1     -- reserved
0        -- Resource Indicator -- RO. tied to 1 to indicate I/O space

Should it be
pmbase_value = pci_read_long(LPCBridge, 0x40) & 0xff80;
?

Is shifting necessary, too (see attached file)?

On my machine, output from my variant:
Extracted address from PMBASE: 0x00000800
Offset to SMI_EN  (PMBASE + 0x30): 0x00000830
Offset to SMI_STS (PMBASE + 0x34): 0x00000834
Value in SMI_EN:  0xffffffff
Value in SMI_STS: 0xffffffff

Output from Stefans variant:
the same as from above

Output from my variant with shift:
Extracted address from PMBASE: 0x00000010
Offset to SMI_EN  (PMBASE + 0x30): 0x00000040
Offset to SMI_STS (PMBASE + 0x34): 0x00000044
Value in SMI_EN:  0x00000801
Value in SMI_STS: 0x00000010

Output from Stefans variant with shift:
the same as from above

Which of these four variants is correct?
