(Yes, I have been using MS-DOS <:( ) It means that a SCSI device responded to a command with an "Illegal Request" response. If you saw what was before it, you would have known which device it was. > - What does that `5 5 5 5 5 5 5 5 5 giving up' mean? I've seen the > numbers before. They are very intriguing, what do they mean? They mean that there are 5 buffers to be flushed, and that after waiting for a while the kernel has decided that it's unable to write them out so it gives up. In your case, they may have been on either disk; the SCSI bus was probably locked so you couldn't write to the SCSI disk, and the IDE bus was probably screwed too. > - What's the `Error: C:0 ...' message. (Cylinder 0, Head 0, Sector 0 > not readable? The bootcode is trying to read 0/0/0 and the BIOS is giving it an error, most likely come through from the IDE disk. > Kees Jan Koster e-mail: dutchman@spase.nl -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
