[parisc-linux] Installation issue on 800/F10.

[Christoph Plattner]

Hello !

You are in similar position than I, the machines are not
supported for now. 

BUT, perhaps I can help you to go some further steps.
The machines have a proprietary bus system and also
proprietary interface chips.

To get my E55 running, I wrote a device driver using
the ROM console (used for the boot monitor) as system
console under Linux. 

Rebuild the linux kernel with CONFIG_PDC_CONSOLE enabled
and follow the help steps for setting up the machine:

1. create "/dev/ttyB0" as character device, major=60,
	minor=0 with
	
	mknod /dev/ttyB0 c 60 0

2. edit /etc/inittab to use ttyB0 instead of ttyS0 
	or tty1, ... to be able to login

3. add or change to kernel parameter line to use

	console=ttyB0

This should work, or let's say, should give process
in booting.

One further point: Be patient on this point of kernel
output. On some machines or dependent of the kernel 
version (or whatever), sometimes you have to wait up
to half a minute here ...

With friendly regards
Christoph
