441 | There are two drivers for MFM/RLL/IDE hard disks. Most people use | ||
442 | the newer enhanced driver, but this old one is still around for two | ||
443 | reasons. Some older systems have strange timing problems and seem to | ||
444 | work only with the old driver (which itself does not work with some | ||
445 | newer systems). The other reason is that the old driver is smaller, | ||
446 | since it lacks the enhanced functionality of the new one. This makes | ||
447 | it a good choice for systems with very tight memory restrictions, or | ||
448 | for systems with only older MFM/RLL/ESDI drives. Choosing the old | ||
449 | driver can save 13 KB or so of kernel memory. | ||
450 | |||
451 | If you want to use this driver together with the new one you have | ||
452 | to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new | ||
453 | driver from probing the primary interface. | ||
454 | |||
455 | If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver | ||
456 | instead of this one. For more detailed information, read the | ||
