My favorite way to do this (has worked with Linux, *BSD, Mac, Win*, Solaris, Tru64, etc) is: dd if=/dev/cdrom of=cd-image.iso bs=1024 then dd if=cd-image.iso of/dev/cdrom bs=1024 just make sure you have room for that file or choice I think sure work is dd if=/dev/cdrom of=/dev/burner bs=1024 just change burner to the real name of cd burner. === Date: Tue, 15 May 2001 15:15:08 -0700 From: Jeremy Zawodny <jzawodn@yahoo-inc.com> To: Aaron T Porter <atporter@primate.net> Cc: svlug@svlug.org Subject: Re: [svlug] Copying Bootable CDs with Linux On Tue, May 15, 2001 at 03:11:10PM -0700, Aaron T Porter wrote: > On Tue, 15 May 2001, Jeremy Zawodny wrote: > > > My task is simple.

Once you get past the mental block of thinking you NEED to use mkisofs, this is the obvious solution. :-) === Date: Tue, 15 May 2001 15:49:59 -0700 (PDT) From: Aaron T Porter <atporter@primate.net> To: Derek Balling <dredd@megacity.org> Cc: svlug@svlug.org Subject: Re: [svlug] Copying Bootable CDs with Linux On Tue, 15 May 2001, Derek Balling wrote: > I've always found, for some reason, that you need to do: > > dd if=/dev/cdrom of=filename.iso bs=1024 count=`isosize /dev/cdrom` > > For some reason, I've always noticed if you overrun it doesn't make a > useable image... least not that I've found. :-/ This also assumes that a cdrom is an iso9660 filesystem. === Date: Tue, 15 May 2001 14:48:21 -0700 From: Robert-Emmanuel Mayssat <emayssat@cemax.com> To: Jeremy Zawodny <jzawodn@yahoo-inc.com> Cc: Aaron T Porter <atporter@primate.net>, svlug@svlug.org Subject: Re: [svlug] Copying Bootable CDs with Linux Jeremy Zawodny [jzawodn@yahoo-inc.com] wrote: > > > On Tue, 15 May 2001, Jeremy Zawodny wrote: > > > > dd if=/dev/cdrom of=cd-image.iso bs=1024 > > Yeah, someone at work just suggested that, too.

No, that's a sure-fire way to get a coaster. === Date: Wed, 16 May 2001 06:17:21 -0600 (MDT) From: "Karl F.
