[SeaBIOS] Removing "legacy option ROM" from boot menu
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 ___ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios

My vgabios.bin is in its proper location. The vgabios is an option rom, so disabling optionroms disables execution of the vga bios. > > Note: This error only occurs when I disable the aforementioned > function.

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 ... -Kevin ___ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
Re: [SeaBIOS] [Qemu-devel] [PATCH v2] add a boot parameter to set reboot timeout

With this option, guest will wait for a given time if not find bootabled device, then reboot. If reboot-timeout is '-1', guest will not reboot, qemu passes '-1' to bios by default. This feature need the new seabios's support. Seabios pulls the value from the fwcfg "file" interface, this interface is used because SeaBIOS needs a reliable way of obtaining a name, value size, and value. It in no way requires that there be a real file on the user's host machine.
