29 * Normally, Linux can get the drive parameters from the BIOS at
30 * startup, but if this for some unfathomable reason fails, you'd
31 * be left stranded. For this case, you can define HD_TYPE, which
32 * contains all necessary info on your harddisk.
33 *
34 * The HD_TYPE macro should look like this:
35 *
36 * #define HD_TYPE { head, sect, cyl, wpcom, lzone, ctl}
37 *
38 * In case of two harddisks, the info should be sepatated by
39 * commas:
40 *
41 * #define HD_TYPE { h,s,c,wpcom,lz,ctl },{ h,s,c,wpcom,lz,ctl }

49 with more than 8 heads.

51 If you want the BIOS to tell what kind of drive you have, just
52 leave HD_TYPE undefined. This is the normal thing to do.
