ISO Error

As far as I know the XP cdwriter can not handle uncompressing an iso
file into it's original directory tree file structure.

Using MS/Windows to get ISO CD images
First of all the .ISO file extension is not supported in the native
MS/Windows world. Sure you can download it from one of the FBSD FTP
sites and burn it to an CD using MS/Windows, but you end up with a
data disk where the ISO file is a single file, not an bootable CD
containing the FBSD directory tree which you need to install from.
The second major problem is you need a fast internet connection,
(IE: ISDN,DSL,CABLE) to download over. Using an 56K modem will take
over 8 hours per CD if you are lucky enough that your ISP does not
cut you off or the FTP server does not get busy and suspend your
session. To resolve this problem of using a MS/Windows box to obtain
the FBSD install cdrom image you will need a MS/Windows FTP program
that can restart the ftp download where it left off at, if it gets
terminated during the initial download. I used SMARTFTP from Then you need a MS/Windows program that can burn
ISO files to cdrom. I used Nero from The downloaded
demo's from these sites work just fine to do what you have to do to
create your FBSD mini install cdrom. Uninstall them, but keep the
downloaded install zip files for them and next time you need to
retrieve an FBSD .iso file, just reinstall to get a new 30 day demo.
