4. Network installation

The network installation has many steps in common with the diskless installation: once again, we will have to set up the rarpd(8), dhcpd(8) and tftpd(8) servers. This time, however, the kernel to boot is bsd.rd instead of bsd. It's a RAM disk kernel which, after boot, provides a RAM-based filesystem containing various interesting utilities for system maintenance and installation. Therefore, the boot configuration file will contain an additional line:

set tty com0
stty com0 19200
boot bsd.rd

To boot from network, on Soekris systems, you must press ctrl-P at system startup to enter into the BIOS menu and then type "boot F0". An absolutely normal boot and installation process will follow:

# cu -l cua00 -s 19200
