With the older Sun CDROM drive and the full debian-hppa iso, the install wa=
s trivial.  One thing that is really remarkable is the "power on to login=
 prompt" speed.  Everything that I have tried so far works great.  This i=
s a brilliant port.

The only hangup I had was installing XFree86.  I tried installing using x-w=
indow-system, which kept failing with twm as a broken dependency (Depend:=
 twm is needed but will not be installed / Sorry, broken package [sic - g=
oing off the top of my head]).  I installed with x-window-system-core, wh=
ich was successful, and then installed individual packages as required (e=
.g. xterm, xdm, etc.)

Thanks for the guidance on the CDROM drive.  That tip might want to find it=
s way into the install documentation for other PARISC rookies.

Cheers,
BB

PS: Now that I have a working machine, how can I help the development effor=
t?

Good news (for me, that is).  A colleague here at work located an older ext=
ernal Sun CDROM, which I believe supports 512k byte segments.  I'll try a=
n install with it this weekend and send an update when I'm successful. (N=
ote the optimism)

Have a good weekend, everyone.

The industry standard (ie, IBM PC world) is 2048 byte sectors, whereas HP
(and Sun) use 512 byte sectors. If you don't have a drive that supports
512 byte sectors, you won't get anywhere. See the post I made (and
subsequent informative posts from others) at
http://lists.parisc-linux.org/pipermail/parisc-linux/2003-November/021645.h=
tml
for more details.

When you boot via tftp you still need a way to communicate with the box,
either using a keyboard and monitor, or (more commonly) via serial
console. Is this the answer to the question you're asking?

Alternatively, when you boot the lifimage I *think* you get the option of
installing from pre-mounted directory (somewhat useless via serial console
- I don't think there's any way to get a shell prompt to premount a
directory), NFS, HTTP or FTP - ie, the usual Debian install methodology. I
suspect your best bet is over NFS.

One thing I noticed is that the config given is using inetd (I use xinetd)
and appears to be using the "standard" tftp, rather than hpa's tftpd. I
recently set up a diskless J200 (imaginatively named "j200"), the config I
used on the server is as follows:

dhcpd.conf:

allow bootp;
option domain-name "fop.ns.ca";
option domain-name-servers 10.2.1.10;
option log-servers 10.2.1.10;
authoritative;
use-host-decl-names on;

host j200 {
  hardware ethernet 08:00:09:8c:d1:41;
  filename "lifimage";
  server-name "10.2.1.10";
  fixed-address 10.2.1.21;
  option subnet-mask 255.255.255.0;
  option broadcast-address 10.2.1.255;
  option routers 10.2.1.200;
  option domain-name "fop.ns.ca";
  option root-path "10.2.1.21:/j200";
}

xinetd.conf:

service tftp
{
       socket_type     =3D dgram
       protocol        =3D udp
       wait            =3D yes
       user            =3D root
       #server         =3D /usr/sbin/tcpd
       #server_args    =3D /usr/sbin/in.tftpd /tftpboot
       server          =3D /usr/sbin/in.tftpd
       server_args     =3D -v -s /tftpboot
       disable         =3D no
}

One tip I noticed is it takes a dog's age to boot with serial console set
to 9600. If you're going to do a serial console, I'd recommend upping the
rate to 19200.

I'm off to Boston tomorrow for a week and a half, but if you're still
having troubles when I get back I can fire up the J200 and write up a
step-by-step if it'd help.

Cheers, Steve
