nope. Don't use hyperterm, it's useless. You've got to use minicom on 
linux or youu will find that you are dropping huge amounts of output.

This is my setup using kermit.  I prefer kermit over minicom.  I have
yet to be able to get linuxbios booting (due to mtd issues), however,
here's my setup that works with the normal kernel boot.  You might need
to augment the speed to 9600 or 19200 instead of 115200.

/etc/lilo.conf contains:
append="console=ttyS1,115200"

~/.kermrc
set modem type none
set line /dev/ttyS1
set speed 115200
set flow rts/cts
set carrier-watch off

You also need to set the speed of the com port via setserial before
starting minicom or kermit.

ie:

# setserial /dev/ttyS1 baud_base 115200

I usually turn all handshaking off.

OK, I am now seeing these K7SEM lockups I think from more than one person, 
happening in that 'set UC on the fixed MTRRs' step.

Is there any chance that recent changes to improve boot time have caused 
trouble in the K7-based boards?

I've seen this symptom on EPIA when the RAM is not correctly
initialized.
I thought that until MTRR is set to UnCacheable, linuxbios_c runs on
cache, not RAM.

At least my modification to enable cache on 0xF0000-0xFFFFF area
is not in CVS.

I still owe you that patch.

I'll commit it, I guess, but this will have to be the last one.

Let's try to all make sure it works ...

Please see Andrew's small hack from yesterday and try it. It is a *very* 
short-term solution and we need a real answer, but it should help you.
