OK... The M1535 South Bridge is set to decode the following address
ranges: (hex)
2e, 2f, 62, 66, 60, 64, 378-37f, 778-77f, 2f0-2f5, 3f7, 3f8-3ff
We want to set bit 4 of b4 so that it will decode 0x2f8-2ff as well.
Unlike the Intel board, it looks like that's the only change needed
to let the driver talk to the IrCC in the chip...

You might still need the setsmc program I supplied, but there may be
some changes needed due to the way ALi implemented their version of
the IrCC. See below...

Oh, and what exactly is BIOSDUMP.EXE? Is that giving PnP data or
what?

I hadn't looked. :-(

It's there, and the main difference between it and the smc-ircc
driver is that the ali-ircc driver runs the FIR and SIR through
a single IO port (COM2) rather than using seperate FIR and SIR
ports.

In fact, the ali-ircc driver looks like it'd work for any smc-ircc
chip, but I can't confirm that until I recompile on my laptop, and/or
get the ALi data sheet for the IrCC functionality. It'd certainly
simplify my task, anyway. But the 47n227 datasheet certainly looks
like it'd party OK.

This makes sense to me, since the port can't be used for SIR and FIR
at the same time, so why not decode them both in the one spot.

Also makes the possibility of Consumer IR mode being hooked in at
some later stage more possible. (I want to use my laptop as a
glorified remote.... ;-)

But you still need to enable the South Bridge to decode 0x2F8
(see above) and to tell the SMSC LPC47n227 that it's second
COM port is at the appropriate address...

Daniele, can you grab the testport (I think....) program I
posted to the list, and try it? If you need to, I can send
it to you off-list (I'm sure these guys don't want to see
it again....)

Your config register looks to be 0x2e so it should work fine
out of the package. But I'd like to know if the SMSC LPC47n227
is already configured or not...
