I finally bought xp pro SP2 manual from Amazon.com. It was less than half the price of Barns and Noble at 59 dollars plus tax. It came in two days.
The question is what does this phrase mean : Mark disk as active
winn32.exe with the following switch /syspart:c
Allows you to copy Setup files to a hard disk, mark the disk as
active, move it to another machine, and restart to continue
Setup on the new computer; must be used with /tempdrive and
can be run only on Windows NT/2000/XP machines.
