src/superio/winbond/w83977tf/w83977tf.h appears to me it's in decimal
format compared to src/superio/nsc/pc87309/pc87309.h which is in
hexadecimal format.  Could this be an issue?

Also, still not getting output after just editing the auto.c and
replacing pc97309 with w83977tf.  One thing I left out was, the ASUS P2B
auto.c impliments w83977tf with the the following (0x3f0) value:
#define SERIAL_DEV PNP_DEV(0x3f0, W83977TF_SP1)

Tyan S1846 uses (0x2e)
/*#define SERIAL_DEV PNP_DEV(0x2e, PC87309_SP1)*/

Basically, I should be getting some linuxbios specific output on ttyS*.
And filo is last with it's output right?

Btw, the w83977tf seems to have been published a year earlier then this
w83977ef/ctf chip.  Just scanning over the pdf files, serial pins look
identical identical.
