I have an IBM EduQuest 40 computer that has a Kingston TurboChip 133 plugged into the overdrive socket, about 1.2 GB hard drive, 20 MB of RAM, and an off brand but SoundBlaster compatible soundcard. I have the CD-ROM drive connected as a slave to the hard drive and it worked fine until I decided to plug it into a Promise Techonologies EIDE card as the master drive there. I left the hard drive hooked into the IDE socket on the motherboard. Windows 95 recognized the CD-ROM drive and I left it at that without using it for a number of weeks. Last week I bought a CD-ROM disk for my 3 year old daughter to introduce her to computers. When I installed the disk into the CD-ROM the drive light lighted up indicating to me for a second that it was accessing the setup files. Next thing I knew the monitor blanked out and the computer re-booted. I tried again -- same thing. I tried another CD-ROM disk that I knew worked in the past for me. Same story. I removed the EIDE card and reinstalled everything as it was before with the CD-ROM hooked as the slave to the hard disk. Guess what! Same story. This seems to only happen in Windows 95 as the CD-ROM works when I boot up using the previous version of MS-DOS although that's since I put it back to the slave to the hard drive. It did have problems under MS-DOS when the EIDE card was installed. My guess is either a bad CD-ROM drive, conflicting IRQ's, or a problem with the connection with the HD. As a matter of fact I did not check to see if the HD is set for master/slave jumper settings. That might be the problem. Anyway I thought I'd throw this out for anyone's advice. Thanks.
