> Nick here: I think you might be missing the ikon
data. According to Tim Neitz the first 12 blocks are
filled by the "editor", and the last 6 by the ikon
data. You can read his note at the end of Tim's nasm
version of CF01, which is in John Comeau's sourceforge
site that you use. If you go to Tim's site you will
see his complete set of nasm source, including data
in the slot "cfinal". He says that his nasm code ought
to compile into a faithful version of the original
native CF01.

icons.asm file. I guess this will compile to be
compatible with the complete 72k of selfbooting native
CF05.com that he also supplies (I use the 16bit color
version). Ray has links with Josh:

posting
a private reply to Ray's post today, including my blog
on
a completely different subject. Sorry.
