First off, thanks to everyone who answered my earlier postings. This has
to be one of the few "technical" groups on the net where you can get such
good technical answers in such a short time. Thanks again.

The Extended partition that I want to mount has more than 1024 Cylinders.
Under dos I use the sector translation ability of my ESDI controller
to trick DOS into believing that I have twice the number of sectors and
half the number of tracks. The ROM BIOS on my PC contains this "Translated"
setup. My question is this, if BSD is unable to read my system setup (and
I had to enter it manually for my other drive.) then what do I tell
it about this new drive, the physical geometry or the logical (translated)
geometry??

Which would I use for:-

a) Mounting the existing dos partition (I assume this is the Translated
   value as this is how dos formated the disk.)

b) Putting BSD on this larger disk (any idea's??)

Thanks 

Fletch
