Hi all,
More details on my OF booting problems:
On 2 Aug, this message from mlan@cpu.lu echoed through cyberspace:
> Anybody have any idea why a 7600 upgraded with a littleJoe G3 card
> can't boot through OF? I always get a 'Default Catch'.
The error messages are:
- on boot:
Default Catch!, code=FFF00400
- on subsequent 'boot' commands:
0> boot Claim failed
ok
0>
I do have a boot-command setting thaht makes sure the disk has had time
to spin up, and retries loading multiple times.
Any thoughts? Anyone able to decode the Default Catch?
Michel

That's an instruction access exception. What were the srr0 and srr1
values? Also, doing ".registers" will show the state of all of the
registers.

The loader is trying to use memory that is already allocated, since it
was allocated by the loader last time. :-)

Hi there,
Anybody have any idea why a 7600 upgraded with a littleJoe G3 card
can't boot through OF? I always get a 'Default Catch'.
I didn't have the leasure to analyze this further, but anyway
FAQ-o-Matic didn't offer any advice.
So far, I've been forced to boot with BootX, which works well, but is a
pain in the rear when testing new kernels (through the fact it forces me
to copy the new kernel over to MacOS).
As has been reported before, mounting HFS partitions directly can
lead to massive filesystem corruption (it happened to me as well...
while accidentaly overwriting an existing file), so I'm now moving my
kernels through a second machine via FTP....
Thanks
Michel

One simple thing that bit me is that the machine can try to boot before
the hard drive hs spun up. This gives the default catch you're seeing,
and it depends on CPU speed.
I fixed it with an OpenFirmware change that I haven't bothered to fully
understand, but which seems to work great. That is:
set
boot-command
to
begin ['] boot catch 1000 ms cr again
(I got this from some unremembered place on the Web that discusses Open
Firmware boot problems...)

I already have this in my bootvars. I will check again, but at first
glance, I don't think this will help.
Thanks anyway ;-)
