Okay, thanks.
The main stuff my System BIOS said about my Hard Drive in the first option bit was:
IDE Channel 0 Master    [Maxtor 6Y200P0]
IDE Channel 0 Slave    [None]
System Memory    524288K
Total Memory    524288K
Is that what I was looking for? 'Cause that seems like quite a random number 

 My HDD is supposed to be 200GB
