[LinuxBIOS] PATCH: IT8673F Super IO support.
by Uwe Hermann Aug. 25, 2006

Aug. 25, 2006

Hi, here's a patch which adds support for the IT8673F Super IO. I cannot test it at the moment (other than that it builds), but it's reasonably similar to the IT8671F, so I think it should work (given that I didn't miss anything important in the datasheet). HTH, Uwe. -- Uwe Hermann http://www.hermann-uwe.de http://www.it-services-uh.de | http://www.crazy-hacks.org http://www.holsham-traders.de | http://www.unmaintained-free-software.org

Hi. VMware and bochs provide the capabilities to simply change their system BIOS. In VMware and Bochs you can set a filename for the BIOS that the Emulator/Virtual Machines shall use. More about: "VMware/Bochs<-->BIOS development/Option ROM development" can be found here: http://etherboot.org/wiki/vmwarebios There are also two links inside the article which refer to the VMware forums.
