Firmware repair

I have a 250GB SATA model WD2500AAJS which I am trying to get setup in my HP a1000y desktop as a slave along with the factory 80GB SATA.  When installed, I get the error message “PRIMARY SLAVE HARD DISK ERROR” “PRESS F1 TO ENTER SETUP”.   When I press F1, the screen goes black with the word WAIT in the center, and locks there.  

I’ve been told that the drive probably has custom firware which has to be changed to make the drive work in a PC.  Does anyone know how to do this or where to get the software?  How would you get past the place where the drive gives the error above, since the PC is locked up at that point?  thanks in advance
