Ok, since this topic keeps coming up on the forum, I decided to make a Wiki page for the subject. There's still a lot of TODOs, but mainly on how Bochs treats out of bound values, and some miscellaneous stuff that's probably not used that much. [[User:Jal|Jal]] 05:44, 5 March 2008 (CST)
: I made some additions with the knowledge I gained during my experiments with BGA in both Bochs and QEMU. I hope you like it. Actually in some cases they behave very differently even if they implement the same protocol. I'm still making some experiments, so at some point I might add more. --[[User:Walling|Walling]] 06:40, 26 October 2008 (UTC)
I tried to follow this document. It seems there might be a problem with the section [[Bochs_VBE_extensions#Using_a_linear_frame_buffer_.28LFB.29|Using a linear frame buffer]]. With version 2.4.1 of bochs, I do an Output Word on the Index IO Port with VBE_DISPI_INDEX_ENABLE and then Output Word on the data port VBE_DISPI_ENABLED | VBE_DISPI_LFB_ENABLED. In the document, it specifies that VBE_DISPI_INDEX_ENABLE | VBE_DISPI_LFB_ENABLED should be sent to the index and then VBE_DISPI_ENABLED on the data port. Can someone confirm this? --[[User:Threesevenths|Threesevenths]] 16:59, 6 August 2009 (UTC)
:You are right, that was a stupid typo. It should read VBE_DISP_ENABLED instead of VBE_DISPO_INDEX_ENABLE. Thanks for noticing it (you can see the code example does it right). [[User:Jal|Jal]] 09:17, 21 October 2009 (UTC)
