Hello,
is it possible to remove the "legacy option ROM" entry from seabios' boot menu list? (I use QEMU). Using make menuconfig I tried to disable "Boot Interfaces --> Option ROMS". After compiling and using the bios.bin I only receive a black screen. My vgabios.bin is in its proper location.
Note: This error only occurs when I disable the aforementioned function. Any clue how to solve this issue? I have seen screenshots where this entry doesn't appear so it seems it's possible to bypass this entry.
TIA,
Alex

The vgabios is an option rom, so disabling optionroms disables execution of the vga bios.

Something in QEMU is passing an additional option rom to SeaBIOS. Try extracting the debug information from seabios:
qemu -chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios ...
