NAME    [Toc]    [Back]

     cdboot - i386-specific second-stage CD-specific bootstrap

DESCRIPTION    [Toc]    [Back]

     cdboot is a modified version of the i386 second-stage  bootstrap program,
     boot(8),  configured  to be run by the OpenBSD El Torito CDROM boot sector
     cdbr.  cdboot will look for an /etc/boot.conf  configuration
file on the
     CD-ROM.   If  it finds one, it processes the commands within
it.

     cdboot then sits in a loop, processing commands given by the
user.  It
     accepts all the commands accepted by boot(8).

     If  no commands are given for a short time, cdboot will then
attempt to
     load an OpenBSD kernel from the CD.  It first looks for  the
install kernel
 bsd.rd in the standard i386 release directory (e.g.
     /3.6/i386/bsd.rd), then for /bsd.  It may be told to boot an
alternative
     kernel, either by commands in the boot.conf file, or by commands typed by
     the user at the boot> prompt.

     used on most CDs.
