Note 4:
The device capacity can sometimes be changed by the BIOS or host adapter board. This may make
actual capacity different from that listed in the table.
Note 5:
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) ×
(96 sectors per track) = 76320
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) ×
(128 sectors per track) = 101760
Note 6:
The number of cylinders for a CVS volume is calculated as follows ( ... means that the value should
be rounded up to the next integer):
OPEN-3/8/9/E: The number of cylinders for a CVS volume = # of cylinders = (capacity (MB)
specified by user) × 1024/720
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of cylinders = 37 × 1024/720 = 52.62
(rounded up to next integer) = 53 cylinders
OPEN-V: The number of cylinders for a CVS volume = # of cylinders = (capacity (MB) specified by
user) × 16/15
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders = 49 × 16/15 = 52.26
(rounded up to next integer) = 53 cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB)
specified by user) × 1024/720 × n
Example
For a CVS LUSE volume with capacity = 37 MB and n = 4:
# of cylinders = 37 × 1024/720 × 4 = 52.62 × 4 = 53 × 4 = 212
OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB) specified
by user) × 16/15 × n
Example
For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4:
# of cylinders = 49 × 16/15 × 4 = 52.26 × 4 = 53 × 4 = 212
