Upgrading the Main Memory
This drive has blocks of 512 bytes each so that one cylinder contains
262144 bytes:
Total number of bytes/cylinder = 512 x 512 = 262144 bytes
This means that 4 cylinders on this drive provide 1MB of storage so that
multiplying the size of a partition in MB by four gives its size in
cylinders.
In this example 96MB must be removed from
home
, 64MB added to
save
and 32MB added to
swap
.
Adding space to the
swap
and
save
partitions means that the start
cylinders for all subsequent partitions must be moved up by a
corresponding amount. In this example, all partitions other than the
root
,
backup
and
usr
partitions must be moved, as illustrated in
