This split into two subjects in my opinion.  The subject of Gert's 
report was not specifying the partition to boot whatsoever, but CMLDR 
wants a partition boot-sector, not the MBR nonsensically patched with 
"cmdcons" where the OEM string should be.

Then Gert suggested the reverse-lookup idea for GRLDR and CMLDR, so that 
one can specify "whatever partition Syslinux is already booted from."

In my opinion, my recent chain.c32 patch for the "fs" option is a 
feature, not a bug.  We already support Recovery Console... If the 
partition is specified.  86 is an even number...  No new features for 
even numbers in general?
