The ISO images built daily for the i386 platform, and based on a Linux 2.4 kernel are no longer functional. This happened when upgrading the build server to Debian Lenny, where the ELF loader borrowed from the system requires a 2.6 kernel. There are offered for download here:

The solution is either to:

• update the kernel used to version 2.6;
• better, implement a dynamic loader supporting kernels 2.4 and above.
