I believe that the problem is that you need SRM support for the
bootloader to boot the IDE disk.  In i386, the bootblocks have BIOS
support for reading off the IDE disk.

If you want to get the install floppy into a state where you can build
kernels, there are a few steps that you'll need to make:
	1.  mount a rw partition on /tmp and maybe /var/tmp.
	2.  modify your PATH to have /mnt/bin.
	3.  remount the root partition rw, and create symlinks from
	    /usr/include and /usr/bin, etc, to /mnt/usr/include, etc.

Something else that you might try would be to cd /mnt and then
./usr/sbin/chroot .

Something along these lines will provide you with an environment where
you can build.
