        I have recently purchased the Complete FreeBSD package(2.2.6).
I am installing it on a pentium 166 with 32 Mb ram. I have a 
Western Digitial hard drive WDC AC32500H (4960cyl, 16hd, 63 spt).
I want to share the drive with Windows NT 4.0 and dos 6.22.
I have the drive partitioned with a 20 MB dos partition at the start
next free space of 250MB (for freeBSD), and the remainder of the 
drive is and extended dos partition, with several logical drives.

When I boot 2.2.6 from a floppy it detects the drive geometry wd0 as 
4960,16,63 (which is the actual drive geometry).  I can obtain the bios
translated geometry as 619,128,63 with pfdisk. I the novice setup
the fdisk partition editor has 620,128,63.  I assume this is because
pfdisk start numbering from 0 and fdisk starts numbering from 1?


On page 36 of the book it state to "Use the drive geometry specified
on the disk itself...".  However, in the novice setup help menu 
(in the section "Installing Boot manager for drive wd0") it states
"...(pfdisk) will report the geometry that dos sees which is generally
the correct one".  Which geometry is the correct on to uses when
installing FreeBSD?

                                Thanks Greg
