>Description:
The installation document describes a procedure to install on i386 over a 
serial console. It recommends to either unplug the keyboard or to interrupt the boot and boot with boot -h.

Boot -h turns out not to work. While all the kernel messages from the probing
appear on both the normal console and the serial one, after mounting the root
file system the system switches entirely to the normal console.

Instead the following procedure will do it (but require at least a keyboard on the machine in question):

- interrupt the boot in the boot menu by pressing 6
- enter the following lines:

set boot_multicons="YES"
set boot_serial="YES"
set console="comconsole"
boot

(I got this from Dmitriy Kirhlarov <dimma at higis.ru>)
>How-To-Repeat:
Burn a install CD and try a serial install according to the current documentation
>Fix:
Fix the documentation (see above).
