problems building vbox rom

[NiKiZe]

I'm assuming you have read the Readme about vbox, copy found at: https://git.ipxe.org/ipxe.git/blob/HEAD:...box/README
And especially the size constraint part.

Remember that when CONFIG=vbox is used, the config files from that directory is used so changes needs to be done in those files (described in more detail at http://ipxe.org/appnote/named_config )

I don't think much features will fit in the above mentioned size constraint, so the usual way to handle that in vbox is to have DHCP config or script that checks the features, and if some feature, such as menu is missing then a more full version of ipxe is loaded over the network first before bzImage can/is booted. One ISC DHCP config that checks the ipxe features option can be found at: https://gist.github.com/robinsmidsrod/40...green-conf I know Robin uses vbox so that config is likely done for just this use-case.
