Does iPXE support IMAGE_COMBOOT

Does iPXE support IMAGE_COMBOOT
I fail to compile iPXE once I remove the sign "#" ahead of IMAGE_COMBOOT in src/config/general.h.

Anybody who know if iPXE still support IMAGE_COMBOOT? Same failure on below as well.
//#define IMAGE_PXE /* PXE image support */
//#define IMAGE_SCRIPT /* iPXE script image support */
//#define IMAGE_BZIMAGE

RE: Does iPXE support IMAGE_COMBOOT
if you make changes and than makes a git diff
or better, add specific lines to config/local/general.h that you want to have. and that post that content.

also show us the line you use to compile, and any error messages that you get.


// is the comment here. # is precompile flag.
Meaning that f you want IMAGE_COMBOT you create
config/local/general.h with:
#define IMAGE_COMBOT

and then compile as usual. however do note, that it is not possible to include combot in an efi build. (which is documented in the FAQ if i'm not mistaken)
Also don't try to enable anything that is already enabled by default, it's just redundant, and makes it harder to debug any issues in the future.

Read FAQ before first post!
Are relevant ipxe.org error urls and PCIIDs included?

RE: Does iPXE support IMAGE_COMBOOT
Ooops, sorry a mistake. The sign I mentioned is not "#" but "//". Smile what I did is to enable the choice.
I searched out some of information that the location to enable IMAGE_COMBOT while compile to remove "//" ahead of the file "config/local/general.h" or "config/general.h". I am not sure which one shall be better. Anyway, I tried three combination but fail,
1.only update "#define IMAGE_COMBOOT" in config/local/general.h
2.update both in "config/local/general.h" and "config/general.h"
3.only update in "config/general.h"

Let me post the contents of config/local/general.h
#define IMAGE_COMBOOT

RE: Does iPXE support IMAGE_COMBOOT
Please restore you config/general.h
only add lines to config/local/general.h that you want to change
Only post config/local/general.h that only contains the relevant changes (feel free to edit your post above)
But your local/general.h looks good, now when you build that it should be good to go, and when you boot it you will see COMBOT in the header features

Oh, right you must have missed that important part:

I git clone a new and do not touch any other files except only create a file named general.h under the folder "src/config/local" with only one line content,
#define IMAGE_COMBOOT

I still get error with command "make bin-x86_64-efi/ipxe.efi EMBED=fix.ipxe"
The contents is :
#!ipxe
dhcp
chain http://myserver/ipxe/menu/boot.ipxe
