Agreed, I am also looking for a good documention. Atleast the flow in terms of implemented functions or assembly code and some kind of Do's and Dont's if any. One good advantage would be more and more people would be easily aware about the code architecture and would get invovled in LinuxBIOS if one is interested.
ivan@munix.com.br wrote I am writing some code to fixup the video chipset trident cyberblade and V1621 RGB->CS encoder , and also trying to fix the IDE_BOOT for my mainboard (B860T or EPIA), so I am looking for information about the real bios process, and about the layout of the common bios files, and of course, any information about bios as possible.
My main problem is to find good documentation about the post, the boot process.
I read on some places which the CS is set F000 and EIP FFF0, so in other websites I had seen CS is FFF0, in other 000F , causing some confusion with me.
I need some documentation about 20bits addressing lines, and the GATE A20 function also.
Tanks in advance.
