|Have you set the jumpers at the back of the roms to the appropiate setting(s) i.e. as 'slaves' on IDE1 and IDE2?|
And do you have the IDE cable(s) plugged into the 40pin connector on the Rom the right way round (although there is usually a guide notch that prevents wrong orientation). The red stripe on the IDE cable always goes to the side nearest the power connector.
One other point is how old are your harddrives? Older models (under 8.4G) may not run properly on newer motherboards. If they are recognised, as soon as a newer ROM drive goes across them on the same IDE, HD detection stops.
Perhaps you could try the HD's on IDE1 and the CD ROMS both on IDE2, setting the roms as slaves in both cases.
Have you let the (Award?) BIOS run thru all checks to properly detect the harddrives and saved the results? (F10/Yes).
These are all basics of course but worth checking.
