For a friend of mine I need to install Debian on a very old Mac mini 1,1! I do several test unsuccess and I find this :

The oldest Mini (macmini1,1) is typically the most problematic, due to bugs in its firmware. When booting off CD/DVD, if there is more than one El Torito boot record on the disc then the firmware gets confused. It tried to offer a choice of the boot options, but it locks up instead. Unfortunately, all of the normal Debian installer options for both i386 and amd64 now include 2 El Torito boot records (one for BIOS boot, and one for EFI boot). Specifically as a workaround for this broken firmware, there is now a new flavour of i386 netinst image. Look for debian-mac-XXX-netinst.iso. This image should boot and install happily on a macmini1,1, giving you a normal Debian installation when it's finished, booting in BIOS mode using GRUB. There's quite a delay before the GRUB menu comes up (~30s or so) - be patient!
I look for
Please someone know where to find it for my Mac mini 1,1 ?debian-mac-XXX-netinst.iso
