Hello, I am having a hell of a time getting serial output from serialice on a Winbond W83627HG. I have tried everything I can think of and hoping someone on the list will be able to help or have suggestions.
Note I do get garbage serial output:

Normally when you get garbage output is is because the baudrates are wrong, but both of my baudrates are 115200 in serialice and host PC. Also the serial console works fine with vendor bios and Linux.
Things I have tried: Tried changing from COM1 to COM2, still garbage output. Tried adding port 0x80 posts and it gets all the way through the mainboard code. Tried changing SuperIO config port from 0x2e to the alternate 0x4e (no output at all). Tried changing CLK from 48Mhz to 24Mhz (no output at all).
Attached is my mainboard config and superiotool output, please take a look and see if there is anything you could suggest. Thanks in advance.

Have you checked that you enable 2e LPC decoding before you actually try to configure the SuperIO? Otherwise your frequency switch will never

to the SuperIO.
On ICH7 that register is called LPC_EN. Not sure what system you are using.
It is ICH4 which I am quite familiar with and yes I have that enabled: pci_write_config16(PCI_ADDR(0, 0x1f, 0, 0xe6), 0x300f);
Any other suggestions?
