[ipxe-devel] Problem with iPXE menu

[James Peltier]

Hi All,

I'm having a bit of trouble with iPXE menus.  I'm trying to allow a user to select the interface that they would like to boot from and this works fine.  However, if someone incorrectly selected the wrong interface, I want them to be able to go back into the menu and reselect the proper one.

When i choose the option to select the boot interface the first time it works and sets the boot-interface variable to the selected network, returns to the menu showing the "Select Boot Interface (DONE)". If I then select this option again it seems to attempt to boot and ends up with an INT18 error.

What am I doing wrong?
