[parisc-linux] Boot console problems

[Philipp Schulte]

Hello,
I am trying to install parisc-linux on a HP 735. The problem is that I
can not specify the boot device. I hit ESC during the boot-process and
I get the menu where I can choose between:

---
a) Boot from specified device
s) Search fpr bootable devices
a) Enter boot administration mpde
x) Exit and continue boot sequence
?) Help

Select from menu:
---

But then nothing happens no matter what key I press. The cursor just
jumps to the "S" of "Select". Even "? <RETURN>" gives no output at
all.
I thought that it might have something to do with my serial console
but I tried using another PC with minicom and got the same result.
If I just let the machine boot to HP-UX then everything works fine, I
can execute commands and stuff.
Does someone know whats going on here or how to avoid this problem?
Regards,
Phil

Philip,

I'm using the serial console on a 735/125 without any problems. Two possibilities:

Your cable - does it have anything special/wrong on the control signals ? Obviously the basic RX/TX and ground work, how about the other signals (DSR/DTR, RTS/CTS) ?

The console configuration and your terminal program aren't using the same parameters (I assume you are using 9600,n,8,1). Eventually the console has been set to something similar but different. The console and the OS can use different settings, which is why it works from the OS but not at the boot prompt.

Hello !

In my oppinion, this has nothing to do with the control lines.
The behavior would be different.

The problem you have, Philipp is the line-feed, carriage return
topic, a always hot topic.
You can simple try to use Ctrl-J (^J) instead of <return>. Or try
to use ^J and then <return> or the other way round. Then the machine 
will perhaps react to your commands !

The problem is simple a setup problem. Tricky is to find a setup
of 
- exchange LF by CR or the other way round
- add LF in some cases
- ignore CR is some cases.

With `stty' on the machine running the front end (minicom) you can
play around, or use `minicom' built in configuration.

With friedly regards
Christoph P.
