Re: Fixing bug #572869: ofpath doesn't work in the absence of /proc/scsi/scsi


I don't know why it stopped working (did you accidentally zap the PRAM?)

But as a solution to the problem of wasting CD-R's, you can buy a CD- RW and use it (I got a 5-pack and rotate thru them -- so I always have 4 backups)

Weird. If I dd the current iso's onto a stick I can't boot from them. I
don't like wasting CD-R's. I did it a dozen times, so I know that it
normally works. The images I download now all suffer from the same
problem. I get an error when trying to boot:

I will need volunteer help to collect more information about SAS, SATA
and SCSI hardware configurations on Power machines.

Please use recent beta or daily Debian powerpc install CD to boot your

On a POWER or 64bit PowerPC machine type:

 boot: install64 video=ofonly

On a headless machine type:

 boot: install64 console=ttyS0,9600n8

on a G3/G4 machine type:

 boot: install video=ofonly

Choose your language, location and keyboard. Let the installer load
additional installer components. On next screen choose <Go Back>. You
may need to repeat <Go Back> until 'Debian installer main menu' shows up.

On 'Debian installer main menu' scroll down and choose "Execute a shell."

When you get the shell prompt type:

 mkdir /info

 uname -a > /info/uname

 cat /proc/cpuinfo > /info/cpuinfo

 lspci -v > /info/lspci

 tar cf /info/device-tree.tar /proc/device-tree

 find /sys -name host\* -o -name ide\* > /info/hosts

 find /sys -name proc_name -o -name devspec > /info/specs

 cat `cat /info/specs` > /info/paths

 ls -l /sys/class/block > /info/blocks

 tar cf /info.tar /info

Mount a thumb drive, floppy disk, or a hard drive and save the
"info.tar" file while renaming it to reflect retail name of the machine.


 mount -t vfat /dev/sdb1 /mnt
 cp /info.tar /mnt/Power520.info.tar
 umount /mnt


 mount -t ext3 /dev/sda3 /mnt
 cp /info.tar /mnt/YDLPowerStation.info.tar
 umount /mnt

Then type:


Finally, email the file back.

Thank you for your time and efforts,
