Here are the brief explanations of drive specifications.
*TYPE : The BIOS contains a table of
*SIZE : Disk drive capacity (approximately). Note that this size is usually slightly greater than the size of a formatted disk given by a
*CYLS : Number of cylinders
*HEAD : Number of heads
*PRECOMP : Write precompensation cylinder
*LANDZ : Landing zone
*SECTOR : Number of sectors
*MODE : AUTO, NORMAL, LARGE, or LBA
-AUTO : The BIOS automatically determines the optimal mode.
-NORMAL : Maximum number of cylinders, heads, and sectors supported are 1024, 16, and 63 respectively.
-LARGE : For drives that do not support LBA and have more than 1024 cylinders.
-LBA (Logical Block Addressing) : During drive access, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address. This will significantly improve data transfer rates for drives with greater than 1024 cylinders.
