Speaking opportunities and CfPs
by Carl-Daniel Hailfinger 25 Jan '09

25 Jan '09

Hi, I'm pretty sure most of us occassionally stumble upon conferences and Calls for Papers where coreboot would fit pretty well. Is there any way to make sure such opportunities don't go unnoticed? Maybe a wiki page? Or should everything be sent to the list? I just found a CfP for the Virus Bulletin 2009 conference which looks like it could make coreboot known in the antivirus industry (which might lead to interesting developments). http://www.virusbtn.com/conference/vb2009/call/index Regards, Carl-Daniel -- http://www.hailfinger.org/

ADLO -> SeaBIOS
by Carl-Daniel Hailfinger 25 Jan '09

25 Jan '09

Hi, the coreboot wiki still suggests to use ADLO for booting Windows and does not mention the usability of SeaBIOS with Windows at all. I tried to add a bit of information, but since I don't have access to any coreboot machine right now, the info I can add is pretty limited. Could someone who uses SeaBIOS please do a wiki search on ADLO and Windows and mention SeaBIOS everywhere as preferred way to get Windows running? Thanks. Regards, Carl-Daniel -- http://www.hailfinger.org/
