I tried ftp://releng4.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/4.5-RC1-cdboot.iso on two machines: Dell Inspiron 3000, Phoenix BIOS 4.0 Release 6.0 Copyright 1985-1997 Build 06/09/98 09:42:22 Inspiron 3000 KM200ST Rev A05 Keyboard BIOS Rev A01 Worked OK, got into the installer Gateway 2000 P5-120, BIOS 1.00.10.BR0T AMIBIOS American Megatrends ... I think the copyright date was 1992, although this machine was manufactured in 1995. Failed (hung) after POST. No messages, floppy disk light seems to stay on a long time. Will there be a way to generate a special bootstrap the old (current) way? This bootstrap should have just enough in it to install enough of the system to build a GENERIC kernel and install that. (B.T.W.: I'm not firmly attached to the Gateway. I was just able to get it cheap and was using it as a proof-of-concept, and as a place to house a 40G drive for my home LAN.) -------------------------- (Taken from the stable-digest mailing list) >Date: Thu, 10 Jan 2002 01:59:47 -0800 (PST) >From: John Baldwin <jhb@FreeBSD.org> >Subject: New cdboot ISO available > >A new experimental CD bootstrap was recently added to -stable for the i386 >architecture that allows the full contents of the CD to be used when booting. >The method we currently uses relies on the BIOS emulating a floppy drive from a >floppy image file on the CD.
