I'm sorry you were surprised. I sent a note last month that I was going to look at this. I am truly sorry for the surprise and for any disappointment. SeaBIOS needs USB support in order to be usable on many platforms. I want SeaBIOS to be a "turn key" solution - that is, I want a vendor to be able to boot up coreboot+seabios and say, "hey, this 'just works'". I would prefer to pull in an external solution than implement a new one. Unfortunately, there isn't an external solution that works today. I looked closely at the libpayload code; I felt it would not work well in the constrained environment that SeaBIOS runs in. I believe libpayload could be extended to support that constrained environment, but I worry that would be an unnecessary burden on the other users of libpayload (which aren't so constrained). The support in SeaBIOS is currently 1029 lines of code - it is a direct, no nonsense, just make it work implementation. >Are you planning to add USB MSC > support as well?

Otherwise, I will continue to add new features as I get time. The next thing I am planning to look at is basic ohci keyboard support, and then fleshing out the current keyboard support (eg, auto-repeat, keyboard leds). -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
