Intel BootUtil no longer understands gPXE/iPXE images?

[Sedorox]

I recently ran into this myself.
If you go and download the latest preboot.exe (I got mine from here:
http://downloadcenter.intel.com/Detail_D...iid=dc_rss
version 17.4, which gives a bootutil.exe version of 1.4.03.0, it apparently does not like the rom format that iPXE presents. When I try to use it, I get the following (I renamed the rom file for later):

>bootutil -nic=1 -up=pxe -file=80861229.iba

Intel® Ethernet Flash Firmware Utility
BootUtil version 1.4.03.0

ERROR: Input file invalid format

Port Network address Series WOL Flash Firmware Version
==== =============== ====== ==== ================== =======
1 0002B365A2E0 10/100 YES Flash Unknown

(Note, echo %errorlevel% shows error 14).
Also, I tried the bootutil in Linux, and got the same error. I also tried many forms of the filename, and it didn't change the error.

However, grabbing the old prorpl.exe, from
http://downloadcenter.intel.com/Detail_D...t&lang=eng
version 10.4, IBAUtil version 3.03.06.00, it works fine, with the following:

>ibautil.exe -nic=1 -restore

Restoring image on NIC1 from file 80861229.IBA...done

NIC Network Address Series WOL Boot ROM Type Version
=== =============== ====== === ================ ========
1 0002B365A2E0 10/100 YES PXE/RPL 88.106.129

Indeed, upon reboot, I'm presented with iPXE.

Trying the suggestion above (also suggested by Sha0 on IRC), I reduced the size of the image, and padded it to the size of one saved from the bootutil, and I still got the same error message.

At this point, it seems either the ROM needs to be saved in a new (or old -- as references to FLB exist in the bootutil docs, but say it's old..) format for the bootutil, or we have to use the old ibautil to flash it.

I also posted to the mailing list, to hopefully spur conversation there too: http://lists.ipxe.org/pipermail/ipxe-dev...01979.html
