I'm having a hard time booting Mandrake 9.0 after installing Promise Ultra ATA/133 Controller. This IDE controller controls my DVD and CD-RW players, not any HDD. What happens is that I get to the first bootscreen after the bootloader. I have WinXP and Mandrake running on the box. XP on the first partition and Mandrake on the second. Worked perfect till I installed the controller. Did a format and reinstalled Mandrake 9.0 & 9.1, but the same happens every time. The DVD/CD-RW drives works just fine...all other drives are detected and working fine, but will not boot linux. Even tried to boot from floppy, but freezes after the hardware detection.

Any ideas I can try are appreciated.
