Well, as long as the values are fairly sane [i.e. allow a bios boot], there is no real reason I can see to care. However, I had to figure out a way to hammer my disk into submission. Its geometry was 62496c 2h 33s. It would barely start reading in the kernel when it would say: xxxx>1024 BIOS limit, and hang. I tried using disklabel to give it the 257c 255h 63s geometry that the controller expects, but the controller still saw the original bad geometry. I gave the 257c 255h 63s parameters to fdisk, and it actually modified the geometry (to 341c 192h 63s, instead of what I entered). Now, the controller and fdisk report 341c 192h 63s, with disklabel reporting 2014c 255h 63s. At least they all got the number of sectors right (4124736). There are some physical problems with the drive, so I don't care to actually fix these other (non-?)problems. -- Zach Heilig
