My setup consists of a hard disk as the primary master, and a CD drive as the secondary master. I have another hard disk on another machine. On that machine, this hard disk was a secondary master. Grub was on the primary master, but that disk is now caput, and the CD-ROM drive on that machine won't boot either a RH9 CD or an FC2 CD. So I think that is caput too. So I think, in order to get at the data on the (presumed) good disk, I will move it to my main machine. I changed the jumper position to turn it into a slave, and I cabled it up as the primary slave. Powering up, the BIOS recognised the disk, but when linux booted from the primary master, it seemed to bring / up as read-only (there were messages such as couldn't re-write /etc/fstab as the system is read-only). So I tried switching it to the secondary controller (as a slave behind the CD drive). This time, the bios did not recognise the presence of a second hard disk, but otherwise I get the same problem. So I have un-plugged the power to the disk, and boot-up is again fine. Does anyone have any idea what might be happening here? -- Colin Paul Adams Preston Lancashire
