On a normal boot, SeaBIOS would be copied to ram at 0xf0000 and coreboot would jump to its elf entry point. On an S3 resume, it is important that coreboot not overwrite the memory at 0xf0000. We could re-use the elf entry point for S3 resume, but because we're not actually deploying the elf into memory it may be simpler to use the standard 16bit entry point (f000:fff0). -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
