Exactly what I was going to say.  gPXE does not currently support base64-
encoded CHAP challenges (or responses).

We have base64 encoding support in core/base64.c, but no decoding support.

Someone will need to add base64_decode() base64_decoded_len() functions, and 
modify iscsi.c to be able to use them; this is probably best done by 
abstracting out the two places that currently process large hex strings into a 
single iscsi_decode_large_binary() function.
