2. To set the disk geometry, press G to select the option Set Drive Geometry. A

dialog box appears, containing numbers like 2055/64/32, representing the

incorrect geometry in cylinders, heads and sectors per head.

3. To calculate the correct geometry, find the total number of sectors by

multiplying the number of cylinders, heads and sectors per head together, then

dividing the number of sectors by the correct number of heads and sectors per

head.

In the above illustration, the virtual disk is a 2055MB disk with 2055 cylinders, 64

heads and 32 sectors per head (these numbers represent the incorrect

geometry). The product of these three numbers (2055 x 64 x 32) equals

4,208,640 sectors.

To determine the correct geometry for the BusLogic compatible virtual SCSI

adapter used by the virtual machine, calculate the number of cylinders, which is

4,208,640 sectors divided by the product of the actual number of heads and

sectors per head (255 heads times 63 sectors per head). This results in a total of

261 actual cylinders (4208640/(255 * 63) = 261, rounded down).
