:No swap or boot:ns#38:nt#13:nc#2075:
:s0#1025050:b0#8192:f0#1024:
:se#512:rm#5400:
Formulas:
nc = nc - ((MB/f0 * ns * nt) * 1000000)
s0 = ns * nt * nc
Example: Calculate a 64MB entry for the ST11200N disk
nc = 2075 - ((64/1024*38*13)*1000000)
nc = 1948
s0=38*13*1948=962312
The new entry becomes:
SEAGATE_ST11200N_noswap|SEAGATE_ST11200N_noreserve:
:No swap or boot:ns#38:nt#13:nc#1948:
:s0#962312:b0#8192:f0#1024:
