Thanks. Can you post the debug output using SeaBIOS' tools/readserial.py program? I'd be curious to see where the time is spent. Also, try the SeaBIOS options CONFIG_THREAD_OPTIONROMS and CONFIG_ATA_DMA. (The ATA DMA can be a little finicky though - fixing it is on my todo list.) -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
