When connecting hard and cd-rom to one ide, the computer does not boot, what should I do?

Question

Hard disks

When connecting a hard drive and cd-rom to one ide, the computer does not boot on the motherboard screen, when the cd-rom is disconnected, everything works

Answer 1

Once upon a time on a home computer there was the same problem and was not treated in any way. The computer sometimes booted from the third time. I smoked the Internet, and discovered that sometimes devices do not care where on the IDE cable to connect, and no jumpers will help.
It turned out that the master should be at the far end of the loop, and the sidir should be at the middle.
I bought a basket in a 5 inch compartment and installed a hard drive above the cider, so I managed to connect the hard at the far end of the cable, leaving the cider on the middle one.
After that, the problem disappeared forever.

Answer 2

I somehow came across an instance that completely ignored any jumpers and always tried to work in Master mode. Perhaps the advice above with connecting to certain places of the loop would help, now there is nothing to check on.

Answer 3

Connect cdrom to a separate ide channel or put it in slave mode

Answer 4

1. Probably a Slave/Master problem - you need to check with jumpers, set the hard drive as a master, CD-rom as a slave. If there are no jumpers on any of the devices, remember that the master is connected to the end of the loop, the slave to the middle - connect a non-configurable device as a master to the end of the loop, switch the jumpers to the second and connect to the middle.
2. On some motherboards, especially those with active sata distribution, they left a truncated IDE port that did not support more than one IDE device in principle

Answer 5

As an option - put the devices on different loops, if possible. But why is it now - the IDE is already kind of a long history ...
