[LinuxBIOS] AMD LinuxBIOS Debug via JTAG
by Bari Ari 27 Jul '06

27 Jul '06

Has anyone worked with the JTAG debug tools from: International Test Technologies µMaster 4010 for AMD® processor boards http://www.intertesttech.com/ate/products_4010.htm They also make a cpu interposers for boards that don't have JTAG or HDT connectors. The interposer plugs into the cpu socket and the cpu plugs into the interposer socket. They don't seem to have them for the latest AMD processors though. http://www.intertesttech.com/ate/products_interposers.htm -Bari

OOps. Forgot to reply to all > Actually, the JTAG debugger (for GX2) is not made by AMD. It is made by > a company called FS2. I don't remember who made the JTAG debugger for > K8. > Yeah supposedly this is TCL code that works with the FS2 and will do things like read and write MSR's and some other stuff. -- Richard A.

[LinuxBIOS] Netvista N2200 8363 (Request)
by Brendan Grieve 27 Jul '06

27 Jul '06

Hi All, I've been playing around on and off for the last few years with these 8363 thin clients made by IBM. They are really brilliant machines and are powerful enough to use either diskless (running local apps via NFS), as thin clients, or as standalone devices (CF). They are also x86 (Cyrix chipset) with a Geode VGA. They have VGA out, sound out, mic in, 2 USB and a NIC. It also has a built in CF card that is seen as hda when used. More info can be found here: http://www.bluetrait.com/archive/2005/08/07/installing-linux-2200-onto-the-… However an issue with them is that the bios that is supplied with them is annoying to say the least. It does not support any boot loaders (lilo/grup etc...) but instead loads up an elf uncompressed kernel. For reasons I'm not yet sure, the kernel (2.4) needs to be compiled by gcc 2.95, and requires various patches to get it to work. I've never got 2.6 working, and never got even 2.4 working with a compiler other than gcc 2.95. However, with the old kernel, I've gotten a pile of these going and they are fantastic. They can play mp3's, play video, and as I test I setup 20 of them with distcc and used them to assist in compiles. Also they are extremely low voltage and could possibly run in a car from the cigarette lighter. I believe that this device is a perfect candidate for LinuxBios. You can pick them up dirt cheap (~$10) from ebay, and in fact there are LOTS of these just floating around, and a decent bios that will allow one the flexibility of loading a newer kernel would be great. You can run them diskless as I mentioned before or can install to CF, with the CF seen as a drive. The bios is a 32ping socketed PLCC AM29F040B. I was wondering if anyone has tried LinuxBios on this and what the results were? Would anyone be willing to get it going? I would be happy to package one of these up, with a working linux distro on its internal CF and mail it (to keep) if it would help. Ideally it would be great if it was possible to be able to boot via NFS (PXE would be brilliant) and also have the option of direct from the internal CF. Cheers, Brendan

Re: [LinuxBIOS] Flashrom support to VIA VT8235

[LinuxBIOS] [QUESTION] VSA2 for OLPC
by Indrek Kruusa 25 Jul '06

25 Jul '06

Hi! The VSA2 bios for OLPC seems to be quite minimal: 64 KB. I would be glad to know: - is there only vsainit and sysmgr inside vsa for olpc? - does audio, ohci/ehci and video handled by kernel drivers? - does OLPC target booting without major problems? It seems to be true but it is better to know for sure ;) Indrek

[LinuxBIOS] Mainboard
by Martin Mayr 24 Jul '06

24 Jul '06

Hello! I read a thread about getting linuxbios work on the PC-Chips M810LR Mainboard from Antony Stone: http://www.linuxbios.org/index.php?title=The_PC_CHIPS_M810LR&redirect=no My question is, if there are any newer boards from pc-chips which are supported by linuxbios. Or are there any other boards like these ones (the opteron boards of tyan are too large for me, i would prefer micro atx), because I only find relative old boards, or the huge ones of tyan. In another thread I read about the win-ent mb06047/48/49. These boards would be definitely too expensive for me. Many thanks in advance, greetings, Martin

It is using NVIDIA nForce3 250. You'd better to find one with Nvidia Nforce 4 or Ck804.

[LinuxBIOS] Code flow of LinuxBIOS
by Anil B G 24 Jul '06

24 Jul '06

Hi, I was just trying to understand the code flow of LinuxBIOS on x86 architecture. I understood that on a power on (cold boot), there is a wait for power good. Later there is a transition from real mode to protected mode (32 bit). The file that makes the transition is entry32.inc of src/cpu/x86/32bit directory. After this point I was not able to make able to make much progress as to which part of the code is executed. Any help in this regard will be helpful. I did check through the available documentation in documentation directory of the source tree, but would appreciate if there are any pointers at the code level. Regards Anil

[LinuxBIOS] newbie: flashrom cannot find flash device
by Wolfgang Spraul 24 Jul '06

24 Jul '06

Hi there - I'm trying to use LinuxBIOS to help me out with a problem I have with a recently acquired Panasonic R5 notebook: Panasonic decided to disable Intel Virtualization Support in the BIOS startup code (WRMSR instruction to set the lock bit in the CPU's Feature Control MSR) without giving me the option to override this in the BIOS menus or offering BIOS updates. So my plan now is this: 'Download' my BIOS (PhoenixBIOS V1.00L13), disassemble & modify the WRMSR instruction, re-flash it onto the board (hopefully the BIOS instructions themselves are not compressed or encrypted). First of all the latest (svn) flashrom does not detect my flash device. From prior posts on this mailing lists I deduced I may have an 'Intel firmware hub'? No idea what that is... flashrom -V output and lspci -V follow below. My questions: 1) Is there a chance I can use flashrom to read/write my BIOS code. What is missing? Can anybody point me in any direction from the flashrom -V output below? Should I open the notebook to try to find any chip label? 2) Has anybody ever 'patched' an off-the-shelf PhoenixBIOS? Is that a realistic proposition at all, or will it be impossible because the binary is compressed/encrypted/signed/whatever? Thanks for your help, Wolfgang Spraul --- flashrom -V output Calibrating delay loop... Setting up microsecond timing loop 302M loops per second ok No LinuxBIOS table found.
