Answer: It is extremely unusual to have received a CD that is corrupt. In many cases, the CDROM itself is not reading the CD properly. One of the following actions may correct the problem,or allow the installation to proceed: 1.) Copy the Setup directory to your hard drive using Windows Explorer. If this fails, attempt it from DOS. 2.) If the CDROM is external, try turning the CD-ROM drive on it's side. As strange as this may sound, in many cases it will change the behavior. 3.) If you are using Windows drivers, switch to the manufacturer's CD-ROM drivers (try the reverse if you are using the manufacturer's drivers). Also, check with your manufacturer to obtain a more recent copy of their driver. 4.) A possible cause may be speed synchronization problems between the processor and CDROM. Try slowing down your microprocessor by taking your machine out of turbo mode and disabling any software that speeds your machine up, such as SmartDrive. If necessary, you can also disable BIOS caching and shadow RAM. 5.) Compare the file size of any files that you suspect are corrupt to the file size of those on your CD. If you can copy the setup directory from the CD to the hard drive, and the file sizes match, then the CD is most likely fine -- the problem is elsewhere. 6.) If the CD-ROM drive simply will not read from the CD at all (and works on other CDs), then replacing the CD with an identical CD will probably not work either. Alternately, you could try using another CD-ROM drive (or copy the files over the network from another machine). 7.) Be sure that this system is using an Intel 80x86- this is the only processor we will support. 7/2/98 10:32:32 AM
