G4's will be much happier with the new-powermac (2.4.x) kernel. > I was able to begin the install with a 2.2.19 kernel I had previously been > installed, but unfortunately I can't complete the installation because the > version numbers don't match in the modules (apparently a 2.2.20 kernel is > provided by r0).

I have run the woody installer on x86 though. I'd try the new-powermac version (with BootX; it won't fit on a floppy). On my machine, which had the video box checked for 2.2, I had to un-check it for the 2.4 kernel. -- *------v--------- Installing Debian GNU/Linux 3.0 --------v------* | <http://www.debian.org/releases/stable/installmanual> | | debian-imac: <http://debian-imac.sourceforge.net> | | Chris Tillman [EMAIL PROTECTED] | | To Have, Give All to All (ACIM) | *----------------------------------------------------------------*
