  48  * Normally, Linux can get the drive parameters from the BIOS at
  49  * startup, but if this for some unfathomable reason fails, you'd
  50  * be left stranded. For this case, you can define HD_TYPE, which
  51  * contains all necessary info on your harddisk.
  52  *
  53  * The HD_TYPE macro should look like this:
  54  *
  55  * #define HD_TYPE { head, sect, cyl, wpcom, lzone, ctl}
  56  *
  57  * In case of two harddisks, the info should be sepatated by
  58  * commas:
  59  *
  60  * #define HD_TYPE { h,s,c,wpcom,lz,ctl },{ h,s,c,wpcom,lz,ctl }

  63  This is an example, two drives, first is type 2, second is type 3:

  67  NOTE: ctl is 0 for all drives with heads<=8, and ctl=8 for drives
  68  with more than 8 heads.
  69 
  70  If you want the BIOS to tell what kind of drive you have, just
  71  leave HD_TYPE undefined. This is the normal thing to do.
