CD-Rom dosn't work on real PC

Post by hunter »

Hello,

I have a big problem with my Atapi driver. If I want to emulate my OS on Virutal-PC or Bochs the driver works well. But if I want to run my OS on a real PC, there is no signal. Now I don't have delay times in the read_from_atapi(...) function. Maby this could be the problem. Can somebody tell me how long I have to wait, to load the next sector and so on?

Sorry for my bad english.

On real hardware ,errors are frecuent ,do you handle them?
Also some instructions fails because you need to send some request to acknowledge operational changes first.
