[ipxe-devel] [PATCH] Add option to configure Press N behavior for non-PnP BIOSes (INT19)

[Paul Sands]

When using INT19 for non-PnP BIOSes, the "Press N to skip booting" 
prompt is displayed. In reading through previous posts to the mailing 
list, I understand that this is by design to allow an otherwise 
unbootable systems to boot. This however, creates the problem of correct 
boot order in certain situations (such as using iPXE for virtualbox / 
vmware). The attached patch provides a new option in the 
src/config/general.h file that gives the ability to invert the "Press N" 
function. If NONPNP_HOOK_INT19_PRESS_N is defined then the prompt is 
changed to "Press N to boot from" and the code is changed to perform 
that function.

I'll be the first to admit that there is probably a more elegant 
solution but in a simple test with virtualbox it seems to work well.
