Yea, I've got a hacked up boot.flp that has a minimum kernel with sbin/init, bin/sh, and etc/rc on an MFS root.. > >Btw., i've also downloaded their guide how to make a bootable CD from >an image, but dismissed it instantly.

It looked like I could make a cd bootable from boot.flp pretty easily, no? The project I'm working on is to have an mpeg player as a stand-alone box. I'd like to pull mpeg content off cdrom. I really don't want to put a hard disk in it. My options are to boot from floppy, or boot from CD. I'd like to use the CD. The problem is that CD-booting is real new and I'm having a bit of a problem figuring out which hardware supports it. After I've found hardware that'll support booting, I'll hack on mkisofs to spit out a bootable image. >-- >cheers, J"org > >joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE >Never trust an operating system you don't have sources for. ;-) eric. -- erich@lodgenet.com http://rrnet.com/~erich erich@rrnet.com
