The 6322 Cylinder BIOS Bug

    "This is one of the most obscure size limitations that you may encounter-- affecting only a small percentage of systems. It appears that the BIOS cannot handle drive geometry with more than 6,322 cylinders. Attempting to set a higher cylinder value than 6322 may cause the PC to hang. This typically limits the capacity on such systems to about [3.04GB or 3.26 billion Bytes] (6,322 cylinders x 16 heads x 63 sectors x 512 Bytes/sector). The best way to correct this problem is to upgrade the BIOS to a version that supports more than 6322 cylinders or install overlay software.

"The significance of 6,322 cylinders is unclear, so there is no apparent reason why this limitation exists."
