questions and report on setting up UMAX Apus 2000 boxes

[Pierre-Philipp Braun <pbraun%nethence.com@localhost>]

Hi,

I've got several UMAX Apus 2000 boxes (Apple clones with a PowerPC 
processor), exact model : 603e/200, not a C500, at last.  This message 
has two parts.  The first part has some questions, the second is some 
kind of report no how I brought a few of this boxes back to file again.

*** Questions ***

1) How come I am (sometimes... if I don't get a DEFAULT CATCH) able to 
boot scsi/sd@3:0 while I cannot see that device in the device list?

2) Most of my Apus boxes have a dead nvram battery, I need to reenter 
the special settings at each poweron or power cable plug.  The 
nvram/battery is a RAYONAC Computer Clock Battery 840 4.5 Volts 
ALKALINE.  Are there any successful reports on building a custom battery 
with standard Alkaline batteries, or are these batteries still available 
 some place?  The nvram/battery is some kind of a little monster, but 
the PINs are pretty standard, just like PC Speaker PINs.

3) Is cmd-alt-n-v supposed to work?  This is the right command to 
initialize the nvram, even further than a set-defaults would do, right? 
 What about cmd-alt-p-r I've seen somewhere, what does it do?

4-5) Some of those boxes I have don't work correctly.  Beside the damn 
DEFAULT CATCH issue I am talking about in the next part of this message, 
I've got:
- jason which has no network interface
- musset which always gets a kernel trap
- salomon which has no network interface
- worst of all, lucrece that didn't even get the GONG sound at power-on. 
 We cleaned-it up here at the lab and it finally GONGs again but 
NOTHING SHOWS UP on the serial console... Such a pitty!

I should clean the PCI slots with F2 spray and/or change the network 
cards for those with the network issue.

For the kernel trap, I don't really know what to do with it.  I doubt it 
is a netbsd bug since I've got no such troubles on the six other machines,

rebooting
I can only guess it's a hardware issue -- any idea what I should look 
into on the musset box?

Finally about the lucrece box which doesn't show anything on the 
console, any hints on how to deal with it?

*** Report on how I got netbsd up and running on the few other boxes 
that had less hardware issues ***
Connect with serial baud rate 38400.

Use that keyboard keys combination to get to the Open Firmware,
        cmd-alt-o-f

Those UMAX Apus boxes have a version 2.0 Open Firmware.

I configured the firmware with the defaults but auto-boot?, kind of 
sparcish way do deal with it,
        set-defaults
        setenv auto-boot? false
        reset-all

I did the setenv load-base 600000 and setenv real-base F00000 but it 
doesn't seem to be mandatory for NetBSD to work.

Most of the time, using the internal CD player, I get this when trying 
to boot,
0 > boot scsi/sd@3:0 DEFAULT CATCH!, code=FFF00300 at   %SRR0: FF80AC9C
  %SRR1: 0000B070
and it hangs...  I need to reboot (ctrl-command-<that fat button on the
upper right corner of the keyboard which looks like backspace>).  I got 
some internal CDs to work but most of them don't and I got like 90% 
DEFAULT CATCHes for one good run.  So I used an external SCSI CD player 
with ID 6,
        boot scsi/sd@6:0 netbsd.macppc

Sometimes it was also asking for the file, so I had to provide an 
argument or an answer to the boot loader: "netbsd.macppc".

Some older references on those UMAX boxes on this list.

note that even if my issue was similar, mine are not C500 in the end, 
but Apus 2000.
