bios errors at startup

[Scotty]

i changed my pc case yesterday to a jeantech appolo case, didn't turn it on after i had finished the change over as it was at about 2 in the morning and i was pretty tired, but anyway when i turned it on this morning the bios displayed two error messages:
1)reading error. defaults will be used... (this is just after the bios displays scanning ide drives)
2)no array defined

i also installed a new dvd whilst i had the pc in pieces, could this be the problem?

thanks for any help

look at the back on the dvd drive and the other drive/s installed, one needs to be master and one needs to be slave

[Scotty]

this drive is the third one on the system and its has been put on cable select as have the other 2, but it is on a different cable and it is on the second outlet on this cable (because it is not long enough, i am going to buy a longer one though.)will this make any difference and should i also put the new drive on slave as well.

thanks

think you need to go into your bios and set everything up again - sounds like it has lost all the info and is using standard guesses, ie without raid setup.
