Just so I understand, with FILO as the payload will linuxbios get us to the bootloader step faster than the current Intel bios? Is that the primary benefit? Also, we wouldn't have the ROM capacity to actually boot straight into a linux kernel. - mo PS: can you please keep my email CCd in your reply? I am not currently subscribed to the list.

[LinuxBIOS] Interest in a Free Software BIOS for Radeon cards?
by Oliver McFadden 18 Dec '07

18 Dec '07

Hello, I'm interested in a free software BIOS for the newer Radeon cards which use the AtomBIOS format. The previous legacy BIOS is completely x86 assembly code unique to each card, but the AtomBIOS is modular and *should* be easier to replace. I haven't really done any serious work on this yet, and it's just a spare time project (which isn't very much because of other projects and real life) but there seems to be some interest. There is some information on my blog (http://olivermcfadden.livejournal.com/) trying to figure out how to flash these cards, but I think it's some kind of GPIO based SPI interface. AMD have released some register information for the Radeon cards (http://www.x.org/docs/AMD/42589_rv630_rrg_1.01o.pdf and http://www.x.org/docs/AMD/RRG-216M56-03oOEM.pdf) and a working AtomBIOS parser in the radeonhd driver (http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-radeonhd;a=summary) I believe the parser in radeonhd is also compiled into the BIOS flashed to the card. I guessed this from some left over preprocessor defines, etc. As far as I know, the AtomBIOS on the card consists of an interpreter in x86 code, some binary scripts executed by the interpreter, and some data tables, all wrapped up inside the PCI expansion ROM format. The opcodes and format of the binary scripts and data tables are described by the parser code, so I think there is enough information, except for how to actually flash the on-card ROM... I don't whether there is much interest for this project, but at least one LinuxBIOS developer seems interested, so let's see where it goes...

[LinuxBIOS] VGA Support on AMD DB800
by Omar Esteves Duarte Filho 18 Dec '07

18 Dec '07

Hello! I'm trying to use LinuxBIOS with the AMD Geode DB800 platform. I'd followed all the instructions in <http://linuxbios.org/VGA_support> http://linuxbios.org/VGA_support but there is no sign of life at the VGA monitor. However, if i disable the VGA support options in the COnfig.lb and Options.lb files, I get the a linux console at the serial port. Has anyone been able to make VGA work with this platform? If so, is there a HOWTO or some documentation that could give a clue? I think i'm missing something... Any help is welcome! :-) Best regards, Omar.

Board manufacturers never publish all the information that is needed in order to fully support a mainboard. The technical documentation is never technical enough for boot firmware development. For a board like this, in particular this means information about PCI device and expansion slot IRQ routing, as well as the proper pin/ball multiplexing configuration required to match how the board has been designed. Possibly there are also some magic GPIO signals that the firmware needs to work the right way to make the system function. This is all known only by the board designers. Usually it can be learned from a little investigation of the board, along with trial and error. The factory BIOS can also help. (Boot it and read the relevant settings.) AMD is also working with the LinuxBIOS project (maybe you've already seen some posts by Marc, Jordan or Libo) so the only thing we may need is some information from Lippert, and sometimes board manufacturers will gladly help with this information. :) I would start out with trying to boot another LX800 target, to see if there's any response at all. It may get you pretty far. //Peter

[LinuxBIOS] [PATCH] IDE legacy port access + UDMA/33 for 440BX boards
by Uwe Hermann 17 Dec '07

See patch. At the very least the IDE legacy port access must be enabled to be able to use FILO. The rest is optional, but I see no reason to not enable it per default.
