The trouble happens long after it loads vmlinuz, when it tries to get initrd image from the second floppy, so I do not think king of bootloader matters here.

What boot loader are you using? It should be loading the initrd, not
the kernel.

The initrd image is slightly smaller as well. I don't think I'll be able to get everything to fit. Either the kernel or initrd would have to shrink by 50% to fit. So you're saying that I should build a separate "root" floppy image that contains the initrd, as has been done in the past? noah -- ___ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html msg24413/pgp0.pgp Description: PGP signature

You need enough on the initrd to bootstrap the installer to the point where it can load the rest of itself from modules or the network.
