Subject: BIOS / acpi correlation
Date: Mon, 7 Feb 2005 20:05:27 +0100 [thread overview]

hi,
Is there any correlation between bios exposed I/O memory ranges and
the SMI commands used in DSDT code ?
i.e: i can control or display information using :
"out %al, $0xb2"
"out %al, $0x84"
In my DSDT, the code do SMI command like:
"Store(arg1, \_SB.SMIA)"
"Store(arg0, \_SB.SMIC)"
"Store(\_SB.SMIC, Local0)"
SMIxx fields (\_SB scope)
"OperationRegion(SMIR, SystemIO, 0xb2, 0x02) { Field(SMIR, ByteAcc,
NoLock ,Preserve) {"
" SMIC, 8"
" SMID, 8"
"}"
and SMIA @ port 0x86.
But i can't find any correlation between the BIOS %eax parameter and
the SMI commands.
Shoudln't they share the same entry point ?
In my case, i can control multiple thermal zone + fan using bios, but
not using ACPI.
I hope my question is clear enough :)
bye
