I recently swapped out the dying power supply of one of our old old Pentium 200 machines. Before the swap the machine had 3 Burners and 1 HD, all IDE. During the swap I removed one of the CD burners, not sure if that could affect the ability to boot, but decided to put in in here anyways. Anyhow, when I set the HD parameters (cycles etc.) incorrectly, it will come back with Invalid System Disk, so I know it's at least reading it, but when set properly, it simply hangs at that spot. The same with a floppy. If the floppy drive is empty, it grunts twice then goes to the HD, but if there is a disk in there, it grunts twice, starts to read the floppy, and hangs. Any help or advice would appreciated. Thank you thank you thank you for at least reading this through

Hi double check all the ribbon connectors again and all plug in cards, you could have a bum power supply. If the cmos is not auto detect mybe it hangs because its looking for the 3rd cd drive?
