Most older prebuilds naturally see ide drives(HDs, optical) set to cable select by default. All a service tech has to do when replacing a drive is simply mount it in and plug it in the way it comes since ide type drives are shipped out from the manufacturer set to CS already.
If the bios on the board there supports larger drives there will be a large capcity drive setting in the bios itself and the following would apply regarding Logical Block Addressing mentioned before.
"LBA has in recent years become the dominant form of
[COLOR=blue! important][COLOR=blue! important]hard [COLOR=blue! important]disk[/color][/color][/color] addressing. Since the
8.4 GB limit of the Int13h interface was reached, it became impossible to express the geometry of large hard disks using cylinder, head and sector numbers, translated or not, while remaining below the Int13h limits of 1,024 cylinders, 256 heads and 63 sectors. Therefore, modern drives are no longer specified in terms of classical geometry, but rather in terms of their total number of user data sectors and addressed using LBA.
See here for more on this."

Even an old I486 system ran here for a period of time saw the option in the bios for enabling large drive support. That would be found in the integrated peripherals or hardware configuration section depending on what bios is used.
You'll likely have to browse the bios on your own since the system manual may not provide enough information about this feature if available. If you run across it there you should see something like "this enables using larger hard drives" or something to that effect once you have it highlighted. On many old boards you had to manually enter the total number of sectors, cylinders, heads you read on the drive's label to see it work.
