Can't get a rom image below 512k?

Was.  I've now removed it and have a 64k rom image (no payload, I must get 
etherboot + IDE into the payload as an elf image [yes, I *have* been scouring 
the mailing lists!]).

Incidentally, I'm running as 2.11.90.0.19 and compiling etherboot 5.0.6 + the 
IDE boot patch found on the list causes problems:

$ make
gcc -E -Wp,-Wall -DASK_BOOT=3 -DANS_DEFAULT=ANS_NETWORK -DMOTD -DIMAGE_MENU 
-DBACKOFF_LIMIT=7 -DCONGESTED -DLINUXBIOS -DCONFIG_TSC_CURRTICKS  
-DCONSOLE_SERIAL -DCOMCONSOLE=0x3f8 -DCOMPRESERVE -DCONFIG_PCI_DIRECT 
-DELF_IMAGE  -DPOLLED_IDE -Os -ffreestanding -fstrength-reduce 
-fomit-frame-pointer -mcpu=i386 -malign-jumps=1 -malign-loops=1 
-malign-functions=1 -Wall -W -Wno-format -Wno-unused -DVERSION_MAJOR=5 
-DVERSION_MINOR=0 -DVERSION=\"5.0.6\" -DRELOC=0x400000  start32.S | as  -o 
bin32/start32.o
{standard input}: Assembler messages:
{standard input}:87: Warning: indirect ljmp without `*'
{standard input}:197: Error: suffix or operands invalid for `ljmp'
make: *** [bin32/start32.o] Error 1

I'm going to upgrade as tomorrow and see if that helps.  as sure is a bicky 
bugger.

*nod* -- I got that figured out this evening.  :-)

Yes, I was using config.example instead of config.etherboot.  My config file 
(attached) is currently payload-less, but I am trying to get etherboot+ide on 
it.

heh, the kernel isn't very useful, but the bzImage is 360625 bytes.  Just IDE 
+ serial console ATM (no networking support).  I think it was just over 400k 
with networking support.

Is there a location where I can find out what all the options are and what 
they mean?  I haven't been able to locate any documentation to that effect 
yet.  Similarly, is there a clear distinction between the Config and config 
files?
