I have a AT clone machine. Lately, I start receiving "Disk boot failure" msg. after power on. I can boot from F/Disk all the time, but not from H/Disk. I have run test program against the controller, it seems okay. If I remove the FD/HD controller and put it back in, I can boot from H/Disk. But after couple boots, the msg. come back again. I am sure there are no chancethat controller is not connect to the M/B well, but I can not explain why it is happening. Any idea may help. Thank you in advance.

Sounds like you have some contamination on the card-edge connector of your controller. Cleaning _lightly_ with a pencil eraser will usually take care of this problem. You can also try using a different slot for the controller. Those slots' contact fingers can sometimes wear out after repeated flexing. -- Roy M.

If by "after a couple boots" you mean after the machine's been up for a while and Ctrl-Alt-Del'd several times, there could be excess heat building up in the neighborhood of the controller.
