- The correct values for a ST-1239A (assuming you have a USER TYPE
- setting in your BIOS but most AMI ones have one) are 818 cylinders, 14
- heads and 36 sectors. This gives 201MB which is correct. Ad's normally
- say this HD has 211MB but that's exactly 211 Million bytes, i.e. 211 *
- 1000 * 1000 bytes. Actually, 211 * 1000 * 1000 ~= 201 * 1024 * 1024
- which is 201MB. If you had another setting with 211MB displayed, you
- would shortly have experienced problems when writing near the end of you
- HD ...

- You will have to install BootManager on the first HD and completely
- reinstall from floppies, but onto D:.
-
- But why not moving the Apps to D: and keep the OSes on C:, for
- simplicity?
