2 digits.



Has been the norm after specifying the interrupts and correcting the
iobase of the ttyS0 port in auto.c

My latest build, will do the following after a warm reboot and yanking
all by 1 sticking of memory:

12 (or sometimes 11)

I don't know if this is progress or not.  Or even if it's just
encountering a memory bug before console init?

Just denoting hex as it's coded. :-/

Just got my other Bios Savior today for my Tyan S1832DL and will give
this 440BX a try.  No need to specify the SuperIO as I've already
verified it's the same as the S1846 you've been working on.

So my S1832DL *should* give me something on serial without too much

I'll try to start building a new tree tomorrow.

Really, I don't see why the DFI P2XBL 440bx isn't giving output as it's
been with it's SuperIO chip since LinuxBiosv1.  All I can think of it's
a bug before console init or bug with enabling early_ttyS0. :-/
