[LinuxBIOS] WORK! :) Power button question
by Hidasi Jozsef May 1, 2006

May 1, 2006

IT WORKS! Thanks for you all! :) Just another low priority question: is there any way to read the status of the power button? I mean it somebody pushed it? -- Best regards, Hidasi mailto:hidi@e-tiger.net

[LinuxBIOS] newbi questions for VIA EPIS MII6000E target
by lists＠seicento.selfip.org May 1, 2006

May 1, 2006

Hi all ... I'm about to make my first attempt to boot my MII6000E from the onboard CF adapter so pleas forgive my possibly stupid questions. I have a few questions regarding this: VIA's fartboot firmware tells me that it's mandatory to use mkelfImage on bothe kernel and initrd, is this also true for linuxBIOS ? Even if vga bios is copied over from original flash will video be blank untill kernel initializes the video card or will it be possible to see the tipical "loading linux ......" and consequent tipical kernel messages on video ? If the latter is possible would I need to avoid passing console to be serial amongst the kernel options ? According to documentation on the linuxBIOS home http://www.linuxbios.org/index.php/Payloads the etherboot payload has bothe ide and net boot capabilities ... will this let me boot from the onboard CF adapter ? What adjustments must I make to the EPIA-M-howto documentation to use the etherboot payload ? Regards David

[LinuxBIOS] Support for Asus A7N8X mainboard with nVidia MCP-T Southbridge?
by alank＠compsoc.nuigalway.ie April 30, 2006

April 30, 2006

Hi, As far as I can see no Asus mainboards are listed as supported by the LinuxBIOS project. My board is an ASUS A7N8X Deluxe rev 2.0 with a nVidia nForce2 MCP-T Southbridge and an nVidia nForce2 SPP Northbridge. My BIOS is a 4MB PLCC with codes: AN8D2 1003 C302 GM J6 I have downloaded the latest snapshot of LinuxBIOSv2, as I said ASUS are not listed under the src/mainboard tree, However /nvidia/ck804 is listed under the southbridge src tree. The following is the output of "lspci -vvv" on my system. I would be very grateful if anyone can tell me is there any current or future support of ASUS planned for LinuxBIOS. regards, Alan Keaveney, Ireland. ======================================================================= 0000:00:00.0 Host bridge: nVidia Corporation nForce2 AGP (different version?)

[LinuxBIOS] Linuxbios Tyan S2882D
by Hidasi Jozsef April 30, 2006

April 30, 2006

Dear List! I've compiled the BIOS for Tyan S2882D dual Opteron system, I've dumped the original videobios (it has good signature:) but seems the BIOS doesn't start it! The other problem is that when I load a kernel the system simply restarts no output at all. May the absense of the videobios cause this? My last message is "Jumping to the entry point" The kernel works fine with the original AMI :( BIOS! The FILO and Etherboot (via network) also does the same! Does anybody have a good linuxbios config for this motherboard? a working binary is welcome too :) I would like to find the problem, but it would be to use failback code instead of flashing the whole chip once and once:) -- Best regards, Hidasi mailto:hidi@e-tiger.net

[LinuxBIOS] State of vt8237 and consequently epia-ms
by Andy Somerville April 29, 2006

April 29, 2006

Hi all, Im new to linuxbios and the mailing list so please excuse any newbie stupidity. I was wondering about the state of vt8237 southbridge support. From my limited understanding of linuxBios this is virtually all that is missing for Epia-MS support since CLE266 northbridge is already supported. I saw a post in february which mentioned vt8237 and that it was being worked on, but I have seen nothing since. Forgive me if Ive missed something. So I guess my overall question is: Is Epia-MS support a near possiblity, and what would it take to produce? Andy

[LinuxBIOS] MB1030 / 3036 VGA: disabling 00:12:4
by Goodrich,Steven April 29, 2006

April 29, 2006

I've looked at the original BIOS source and the internal versions of the documentation, and here's what I've determined: As near as I can tell, you cannot disable the PCI header for the device at 00:12:4. The original BIOS (written by others on the BIOS team here at AMD in Colorado) virtualized the PCI headers via SMM code, and that header was masked when internal graphics were disabled. Without SMM code, you cannot do the same thing. Interesting info/notes: If you disable memory space via the PCI header (PCI header register 04, bit 1 -- clear to zero), you should disable it somewhat. If the F4 Video Configuration trap bit (F0, Index 42h, bit 1) is set, the system will generate SMIs when trying to access the PCI header registers. This should be clear for a non-SMM system. I suppose you could special-case the device in your PCI scan/enumeration code, but that is probably more kludgy than you'd like. Could you reduce the device's resource requirements to zero? -- Steve G. Steve Goodrich (Steven.Goodrich(a)amd.com <mailto:Steven.Goodrich@amd.com> ) Advanced Micro Devices, Inc. 1351 S.

Re: [LinuxBIOS] MB1030 / 3036 VGA comes up :D
by Goodrich,Steven April 28, 2006

April 28, 2006

In our BIOS for the related platform, I don't see how we're disabling PCI. I see that we set DC_FB_ST_OFFSET (GX_BASE + 0x8310) to 0 and also DC_DUR_ST_OFFSET (GX_BASE + 0x8318). Is the 00:12:4 a PCI address? Does that decode to Bus 0, Device 12 (decimal?), Function 4? -- Steve G.
