Help text

There are two drivers for MFM/RLL/IDE disks. Most people use just the new enhanced driver by itself. This option however installs the old hard disk driver to control the primary IDE/disk interface in the system, leaving the new enhanced IDE driver to take care of only the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from having an IDE/ATAPI CD-ROM or tape drive connected to the primary IDE interface. Choosing this option may be useful for older systems which have MFM/RLL/ESDI controller+drives at the primary port address (0x1f0), along with IDE drives at the secondary/3rd/4th port addresses.

Normally, just say N here; you will then use the new driver for all 4 interfaces.
