Loading PNG for console on older hardware broken

[pxe_curious]

I had built a undionly.kpxe back in April 2017 and that was working fine.

I recently rebuilt it with latest commits as of July 17, 2018.

The following command worked before:

Code:

console --picture ${main-url}/ipxe/background.png --left 48 --right 48 --top 40 --bottom 105

With the latest build of the undionly.kpxe file, that command fails with the following:
http://ipxe.org/err/2d8c20

Per the error page, this is apparently traced back to arch/x86/interface/pcbios/vesafb.c (line 344). But this file has not been changed since the last time I built that binary. I locked at a few other files that might have been related and that were changed, but the changes there do not look like they could be causing this.

The hardware that is now failing is a Supermicro X7SBE, just for reference - it is old . Other, newer, hardware works fine.

When I restored the previous version of the undionly.kpxe file, the menu and background picture continued to work like expected.

The full error message I am seeing at the console, after the background image is successfully downloaded, is:

Code:

Could not configure console: No such file or directory (http://ipxe.org/2d8c203b)
Could not boot image: No such file or directory (http://ipxe.org/2d8c203b)
No more network devices

Press Ctrl-B for the iPXE command line...

And the script dies at that point and does not show a menu.

Does anyone have any insight as to what changes could have caused this?
