Re: [coreboot] Porting coreboot to the Asus P5G41T-M LX motherboard

[Renze Nicolai]

Hi Martin,

Autoport wasn't much use to me since it didn't recognize anything.
However it left behind all kinds of logs like the full lspci output and
stuff like that -> that's why I shared it.

https://github.com/rnplus/test-coreboot-for-asus-p5g41t-m-lx/blob/maste
r/superiodump

https://github.com/rnplus/test-coreboot-for-asus-p5g41t-m-lx/blob/maste
r/superioextradump

This is the output of superiotool using the OEM BIOS.

The SIO is configured for 0x2E.

Greetings,
Renze

Porting coreboot to the Asus P5G41T-M LX motherboard

[Martin Roth]

Ok, looking at the differences between your code ant the GA-G41M code, I
think you might want to add back in the ich7_enable_lpc() function (or
something equivalent) .  My guess is that you're not sending the necessary
IO ports out to LPC.
