Jumper settings one to Cable Select, the Other to Slave.
It seems no other jumper setting works, though I must
not have tried all combinations.
You may have stumbled upon this already, but for the benefit of others...
The one thing that pops out to me is your notes on HDD settings...Yes...
I'm not sure if a machine as old as yours supports Cable Select. It might, the manual for it should say for sure.
Either way, if you do use Cable Select, both HDDs on the same IDE cable must have their jumpers set to CS. Then the HDD on the last connector (on the Primary IDE cable) becomes hd0, and the one on the middle connector becomes hd1.
If the machine doesn't support CS, then you want to set the jumpers on one drive to Master, and Slave on the other. Then it doesn't matter which connector the drive is connected to.
Personally, on that machine, I would use the Master/Slave settings.
If you don't need the 6GB drive, I would not even bother having it in the computer. I would just have the 20GB on the primary IDE, and the CD on the secondary IDE. If you do need both drives, then I would put the 20GB as master in primary IDE, CD as slave on primary IDE, and 6GB drive as master on the secondary IDE
I did not see why this should have any effect at this point in the process as I was not even trying to use the disks.
_However_ your suggestions about the CD drive prompted me to question my set-up. In fact I have two CD drives on my secondary IDE. I was using the slave. Having now placed the ubuntu CD-ROM in the master, I can boot and get the system up and running (very slow, but I suppose that's the name of the game).
I still got one of those messages 'cdrom: open failed', and I also got a good few IDE error messages, but the Kernel did not crash in panic and I have the ubuntu GUI with the Examples and Install icons on the desktop. Currently going through the Install...
Will try this list again, undoubtedly, when I stumble across another tree.
Hmmm, well, I'm not entirely surprised that there were issues trying to boot from the secondary IDE slave CD drive. If there are still troubles, try having _only_ the 20GB HDD connected as Primary Master, and the faster/newer CD drive as Secondary Master.
As far as my suggestion on drive locations, it's related to what gets used more. About 90% of the time, CD drives aren't used. So if you have the2 HDDs on separate channels, there is no congestion to fight with from the other HDD. Same reason that when you setup a software RAID system, you put only one drive on each IDE channel - performance.
