149 The AHA-1522 BIOS calculates the geometry by fixing the number of heads
156 BIOSes of some newer controllers based on the AIC-6260/6360 support
157 extended translation.  This means that the BIOS uses 255 for heads,
169 - for disks<1GB: use default translation (C/32/64)
171 - for disks>1GB:
173   - take current geometry from the partition table
175     ie. either (C/32/64) or (C/63/255)).  This can be extended translation
178   - if that fails, take extended translation if enabled by override,
