o2 boot problem. Newbie ... I think I broke it :( - theonlyandyt - 12-03-2022
Hello lovely Irix people. I was a user if Irix 25+ years ago, working in VFX. I have an o2 which I dug out of the loft. It is to be used in a youtube video showing of some software that I haven't seen any video of. Anyways....
I was so close.
I managed to get irix booting and all the software all working fine. I wanted to change the network settings in order to get some footage on the machine. I changed two things
1. network IP address (to one that would work on my local network)
2. I changed the exportfs file. I commented out a line as it seemed to point to an empty folder
On rebooting to take the new IP I get:
----

Is my hard drive dead? Or did I break something. Thanks in advance

Some env variables seem to have wrong names/values:
monitor==h
SystemPartition===pci(0)scsi(0)disk(1)rdisk(0)partition(8)
OSLoadPartition=n==pci(0)scsi(0)disk(1)rdisk(0)partition(8)
OSLoadFilename=me==/unix
OSLoader=der==sash
crt_option=tion==1
Try changing them:
monitor=h
SystemPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(8)
OSLoadPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(8)
OSLoadFilename=/unix
OSLoader=sash
crt_option=1
Good luck!

RE: o2 boot problem. Newbie ... I think I broke it :( - TruHobbyist - 12-03-2022
Use setenv to change these variables:
setenv monitor h
You can also enter the command 'help' (without the quotes) at the PROM command monitor for more help on commands.

Sorry fir the late reply. As Christmas approaches, time just disappears. Thanks for you insight. I have managed to fix the env variables. But unfortunately I still can't boot as I get a different error.
Autoboot failed
pci(0)scsi(0)disk(1)rdisk(0)partition(8)/unix no such file or directory
So now....
printenv returns:

console=g

sgilogo=y

which I think is all correct but.. I think it's missing a "kername"
any idea what that variable should be set to?
RE: o2 boot problem. Newbie ... I think I broke it :( - robespierre - 12-12-2022
partition(8) is the volume header: the OS loader sash lives there, but the kernel unix does not. It lives in the root partition (0).
SystemPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(8)
is correct, but OSLoadPartition should be
OSLoadPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(0)
you can simply run 'ls' from the PROM command line and you will see that /unix is not in partition(8).
You don't need to set kernname, it is automatically set by sash.
