  37  * Normally, Linux can get the drive parameters from the BIOS at
  38  * startup, but if this for some unfathomable reason fails, you'd
  39  * be left stranded. For this case, you can define HD_TYPE, which
  40  * contains all necessary info on your harddisk.
  41  *
  42  * The HD_TYPE macro should look like this:
  43  *
  44  * #define HD_TYPE { head, sect, cyl, wpcom, lzone, ctl}
  45  *
  46  * In case of two harddisks, the info should be sepatated by
  47  * commas:
  48  *
  49  * #define HD_TYPE { h,s,c,wpcom,lz,ctl },{ h,s,c,wpcom,lz,ctl }

  52  This is an example, two drives, first is type 2, second is type 3:
  53 
  54 #define HD_TYPE { 4,17,615,300,615,8 }, { 6,17,615,300,615,0 }
  55 
  56  NOTE: ctl is 0 for all drives with heads<=8, and ctl=8 for drives
  57  with more than 8 heads.
  58 
  59  If you want the BIOS to tell what kind of drive you have, just
  60  leave HD_TYPE undefined. This is the normal thing to do.
