#If using the hardware cursor, make sure the cursor shape is initialized,
#otherwise we won't be able to see anything if the system firmware has
#either not initialized it, or initialized it to "invlisible".
changed the shape of the cursor to something "too big" or "not small enough"
Normally the cursor is initialized by most BIOS's to a smaller size.
By setting curstart to 0xe instead of 0xb things are back to normal.
