God, I don't think its my problem any more! I created a sparc boot |
| 70 |
floppy image using dd(1) with the image I got from: |
| 71 |
|
| 72 |
http://mirror.israel.net/pub/redhat/linux/4.2/en/os/sparc/images/boot.img |
| 73 |
|
| 74 |
This image, said should be able to boot, still produce the above error |
| 75 |
in OBP. I also googled around, lots of people are asking the same |
| 76 |
question (why cannot boot from floppy) and given no satisfying answer. |
| 77 |
Perhaps this is an UltraSparc problem |
