power to but no I/O to harddrive
Posted on 1998-10-03
I tried installing a cd-rom on a 486 AST computer. Seemed simple enough. I put the cdrom as slave on the harddrive ribbon cable. Put it all together, nothing worked. Went back and put things as they were. No luck. Took every thing out, put back together piece by piece. I have the floppy working. There is power to floppy, 5 1/4, cd-rom, and HD. I used the startup disk but can't get things going. When I start up, I can hear the HD working but can't get it to come on line. I've tried using DOS but I'm not familier with it. None of the commands seem to let me into the HD.
This is a project unit to gain experience with. I want to have a good understanding how things work inside before I open my other unit. It's working and under warranty. :)
There's power to the HD, and when the unit is started you can hear the HD clicking (normal 4 this one), but I'm unable to get any input/output fron the HD. The cdrom is on the same ribbon as the HD. Is there any way of cking to see if there are signals going to the HD and/or cdrom?
