I know there was a limitation with around 504MB or so, but I don't recall 200MB. Are you sure it's not a partitioning problem or something? By the K6 era, most all those computers could accept "GIG" range without a problem. I should know, my first "new" computer way back when was an AMD K6-2 333MHz with a whopping 3.2GB HD, later upgraded to a 40GB.
