This is a 486DX 33 with 16M RAM and an Adaptec 1742 EISA controler running 2.1.0-R the CD is an external Sun (Sony) we used in the past with Sparc machines.

We have used it for serving data bases without problems, then it was unused for the last 3 months. I double checked cables, termination, etc and all seems Ok. Do I have a hardware problem here (this systems stays up forever if I'm not using the CD) ? Pedro
