update the BLK_DEV_HD help text
Many people will see this option the first time now that it is in
drivers/block/
Make it clear that virtually noone needs it.

Most people use - the newer enhanced driver, but this old one is still around for two - reasons. Some older systems have strange timing problems and seem to - work only with the old driver (which itself does not work with some - newer systems). The other reason is that the old driver is smaller, - since it lacks the enhanced functionality of the new one. This makes - it a good choice for systems with very tight memory restrictions, or - for systems with only older MFM/RLL/ESDI drives. Choosing the old - driver can save 13 KB or so of kernel memory. - - If you want to use this driver together with the new one you have - to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new - driver from probing the primary interface. - - If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver - instead of this one. For more detailed information, read the - Disk-HOWTO, available from - <http://www.tldp.org/docs.html#howto>. + This is a very old hard disk driver that lacks the enhanced + functionality of the newer ones. + + It is required for systems with ancient MFM/RLL/ESDI drives. + + If unsure, say N. endif # BLK_DEV |
