The problem is more likely to be with the CD-ROM extension. I too have a clone (from Computer Warehouse which I think originally emanates from Power Computing) and my CD-ROM will not work with the CD-ROM extension which comes with system 8. I am using version 5.3 of the extension which is fine. Your System file is almost certainly screwed so you might as well dump it. It took me the best part of a day to sort out a similar set of problems I had with my machine but I hope I may be able to save you some time. If you have the CD-ROM for system 7.x.x then try booting from this. Hold down the letter 'C' to do this. On my system, you have to do this at exactly the right time otherwise the machine tries to boot from the hard disk. So try it a few times until you find the precise moment. If you can boot from a system 7 CD, then almost certainly, you have the same problem with the CD-ROM extension as I have. How kind of the manufacturers of our machines to let us know about this problem. I had to read about it on the US Apple Web pages. If you have successfully booted from a system 7 CD, you now have the problem of sorting out your hard disk. I have a 6 gig external drive so I just put system 7.5.3 on that, then set the external drive as the start up drive, then I restarted the system, put the system 8 CD into the CD-ROM drive and then re-installed system 8 on the internal drive. This works because the CD-ROM extension is not overwritten until the next restart. So, keep a copy of CD-ROM extension 5.3 (or anything other than the one that comes with system 8) so that you can replace it in the system folder at the appropriate time. This may not help you much if you do not have an external drive. You might be able to install system 7.x.x on a RAM disk, I suppose. Then make that the startup (Can you do this? I don't know because I never use a RAM disk). I checked and the version of system 7 which I installed on my external drive takes up about 42 megs so RAM should not be a problem for you. What you are aiming to do is to get a system running with the CD-ROM drive free and with a version of the CD-ROM extension installed which will enable you to run the System 8 CD-ROM (but not as the boot disk). If you can get to that stage, the rest is easy except that there are always those extras that you have to set up again etc. If a RAM disk is no good, do you have a Zip drive on your machine? > Any instructions or tips are needed. I am in a world of hurt. I know just how you feel. I hope the advice I have offered is helpful. Others have suggested using disk first aid, etc. This is always sound advice but you need to get something running before you can follow it. I get the idea from your description that nothing works at present. Email me if you think I can be of further assistance. Good luck Terry
