Yes, this is the general case AFAIK, other than the below.

I reviewed this message during my initial research, and this seems to
point to what I need to get started. I'll have to dig around CVS and see
what I can find.=20

Christoph, is there anything specific I should look at? Have you had any
further trials?

Many Thanks!!!

Hello, welcome to the PA-RISC hacker group

(I hope you are a new hacker ....)


We E55 users have to work and fight very hard !!!
We cannot accept to read a sentence like `not supported' !!!

Ok, let us come to the facts.
The E55 is a nice server, but it includes many proprietary parts.
These are the I/O bus system, and the following devices:
	MUX 8/16-way serial interface (also affected is the serial
					console)
	Parallel port (not so important in the first run)
	Complete SCSI system

The CPU (core systemw with RAM/Cache) and the ethernet is working
well and quite with a good performace.

It was very important for me to boot this machine. The image booting
via ethernet (BOOTP/TFTP) works very well. The first step was to get
an running console (serial).

For this I started with a hack, using the ROM PDC console via a
polling driver, and so I could start the machine June 2001.

End of 2001 I rewrote this driver as clean one, and Ryan added the
config stuff. So you can use the default linux PA-RISC kernel to
boot the E55 as "diskless server" via NFS-ROOT and a serial ROM
console.

What to do:
-----------

Checkout a kernel, and enable the PDC ROM console in the "Character
Devices" under the "Non-standard serial support". Further follow the
<HELP> instructions for this driver (Creating a /dev/ttyB0, and use
this device as login device).

With this driver we have a chance to do further development on the
device driver programming. I am waiting on documentation to help
developing drivers, but I have to wait.

HELLO ot the others. What is the status on the docu or drivers ?

Good luck in starting up the E55 (it is quite straignt and no real
hacks or patches are needed !).

You can get a lifimage with PDC enabled there:
http://pateam.esiee.fr/cd-
images/lifimages/lifimage-2.4.18-pa32-PDC-20020531.gz

There is also a corresponding netinst iso available on this site.

Robbert Stanford, who is hacking K-Class, reported this on the IRC:
15:48:23 <robbie>       the lifimage worked fine
15:49:00 <robbie>       however the kernel that was installed from=20
debian.org wasnt pdc enabled
15:52:44 <robbie>       thibaut:  on eother thing, but its more related=20=

to the install, i had to exit to a shell and manually edit=20
/target/etc/inittab and inittab.real to use /dev/ttyB0
15:55:29 <robbie>       which isnt realy a big deal, knowing one has to=20=

use ttyB0 with the lifimage pretty well means you oughta know enough=20
about sysVinit to check inittab when things go awry on your first boot

About the inittab.real hack, maybe Richard Hirst will see whether some=20=

tweaks to the default boot-floppies have to be done ;o)

Anyway, I hope this will help you.
