Greetings,
I have a backup of my tivo with all of my hacks in place and am trying to make a self booting cd based on mfstools2.0. I am using nero6 and have tried 5.5, but every disk I've' burned boots part of the way and I get the error message
"Linux invalid compressed (err=2)" Am I missing a setting in nero?
Strangely enough if I rawwrite the floppy and boot from the floppy it sees the cd and behaves normally.
I've tried different media, and slowed the burning speed down.
Any suggestions.
Thanks,
Michael

Since you are making a linux boot CD, try looking here (http://www.tldp.org/HOWTO/Bootdisk-HOWTO/cd-roms.html).

I know getting a working boot CD can be difficult. You need to do the El Torito dance, and have a valid boot.img from a working floppy diskette. As for Nero6, now that you've created a working floppy you can try the "CD-ROM (Boot)" template and turn off Joliet extensions. Just make it a regular ISO9660 CD.

Been there, read that, understood most of that. :)
The floppy image made from the image on mfstools2.0 boot cd works fine. I believe, and could easily be mistaken, that I am doing something wrong in nero with reguards to creating a linux boot disk. I have tried with and without floopy emulation. When I use a win98startup disk as the boot image and use nero's default settings and same media the boot cd works.
Thanks,
Michael

In the linked page example (link above) it uses dd to create the boot.img file and mkisofs to create the ISO image. If you have a fairly basic cygwin install or something, you could make those files you need. Or even an existing ISO CD, like one of the linux "rescue CDs" to boot up, and then create your own little tivo ISO from within a real linux system.

I'm downloading Knoppix now. I thought the floppy had all of the necessary info to boot with.

Thanks,
