Fixed.
+ Setting this option causes the kernel to use your Promise IDE disk + controller as an ordinary IDE controller, rather than as a FastTrak + RAID controller (RAID is a system for using multiple physical disks + as one virtual disk). + + You need to say Y here if you have one of the above mentioned IDE + interfaces, but either you do not have a RAID disk array, or you + wish to use the Linux internal RAID software (/dev/mdX). + + If you wish to use your Promise controller to control a FastTrak + RAID disk array, you need to say Y here AND you you must also say Y + to CONFIG_BLK_DEV_ATARAID_PDC.
This sounds awful. ;-)
Use controller even if marked as disabled by BIOS CONFIG_PDC202XX_FORCE
Say Y unless you want to use Promise proprietary RAID driver.
Makes a lot more sense IMHO. BTW it needs to be split-up for old and new driver (hint, hint!).

No, they are the same (see drivers/ide/Kconfig).
Thanks, Bartlomiej
