3 Bootstrap Setup

Download bootfiles: Download the kern.flp and mfsroot.flp floppy images.

Set up tftp/pxe-boot directory:

Put pxeboot in the boot directory:

# rm -rf /usr/obj/*
# cd /usr/src/sys/boot
# make
# cp /usr/src/sys/boot/i386/pxeldr/pxeboot /usr/tftpboot

Using the vndevice mount the kern.flp file and copy its contents to /usr/tftpboot:

# mdconfig -a -t vnode -f kern.flp -u 0 # (vnconfig vn0 kern.flp) associate a vndevice with the file
# mount /dev/md0 /mnt # (mount /dev/vn0 /mnt) mount it
# cp -R /mnt /usr/tftpboot # copy the contents to /usr/tftpboot
# umount /mnt              # unmount it
# vnconfig -u vn0          # disassociate the vndevice from the file

Compile a custom kernel for the clients (particularly to avoid the device config screen at boot) and stick it in /usr/tftpboot.
Make a special loader.rc to and install it in /usr/tftpboot/boot/loader.rc so that it does not prompt for the second disk, here is mine.

Extract the installer and helper utilities from the mfsroot disk and uncompress them, put them in /usr/tftpboot as well:

# vnconfig vn0 mfsroot.flp         # associate a vndevice with the file
# mount /dev/vn0 /mnt              # mount it
# cp /mnt/mfsroot.gz /usr/tftpboot # copy the contents to /usr/tftpboot
# umount /mnt                      # unmount it
# vnconfig -u vn0                  # disassociate the vndevice from the file
# cd /usr/tftpboot                 # get into the pxeboot directory
# gunzip mfsroot.gz                # uncompress the mfsroot

Make your sysinstall script install.cfg, you can use mine as a template, but you must edit it.

Copy the sysinstall script into the extracted and uncompressed mfsroot image:

# cd /usr/tftpboot
# vnconfig vn0 mfsroot
# mount /dev/vn0 /mnt
# cp install.cfg /mnt
# umount /mnt
# vnconfig -u vn0
