The memstick.img is very large because it contains fixit. I download the
smaller disc1.iso and then use the following script to write it to a usb
stick drive. There is no need to do a FTP-install because the disc1.iso
has everything needed to install from.
The thing you have to keep in mind is that some bios older that 2008 do
not have option to boot from USB sticks or only can boot from some
vendors USB sticks not all of them.
#!/bin/sh
#Purpose = Use to transfer the FreeBSD install cd1 to
# a bootable 1GB USB flash drive so it can be used to install from.
# First fetch the FreeBSD 8.0-RELEASE-i386-disc1.iso to your
# hard drive /usr. Then execute this script from the command line
#
# fbsd2usb /usr/8.0-RELEASE-i386-disc1.iso /usr/8.0-disc1.img
#
# Change system bios to boot from USB-dd and away you go.
# NOTE: This script has to be run from root and your 1GB USB flash drive
# has to be plugged in before running this script.
# On the command line enter fbsd2usb iso-path img-path
# You can set some variables here. Edit them to fit your needs.
# Set serial variable to 0 if you don't want serial console at all,
# 1 if you want comconsole and 2 if you want comconsole and vidconsole
