Random ideas: - hack the tvout stuff into seabios instead of coreboot - place the tvout stuff in an elf, and have seabios run it like a payload - place the tvout stuff into an option rom and tell seabios to run it - teach seabios to return to coreboot - run the vga bios from both coreboot and seabios and hope it doesn't reset your registers - initialize the vga card without a vgabios; replace factory vgabios with the open source vga bios -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
