[LinuxBIOS] issue tracker and doxygen working again
by Ronald G Minnich 06 Feb '06

06 Feb '06

ok, first, I took all the virus-laden isue tracker crap that the bad guys put in and resolved it as follows: resolved: people who do this type of thing are worthless pudknockers. I will try to start closing out issues again. Second, make documentation works again. This is pretty nice, you get web pages, a latex document, and man pages. Missing is the pass over all the include files, I'll try to wrap that up too. Note that for a given target, doxygen ONLY is run on the source files for that target. So the html, latex, and man pages are in a sense custome for that target. You can also browse the source, structs, etc.; this may help with comprehension (I sure hope so!) To test this, on, e.g. via/epia ./buildtarget via/epia cd via/epia/epia/fallback make documentation firefox html/index.html thanks ron

Re: [LinuxBIOS] Flash Programmer recommendation [Was: IWILL DK8-HTX]

phil wrote: > What hardware flash programmer would you suggest to get started? Enhanced Willem Universal Programmer There are several different versions. The most recent one was on eBay for as little as $40 or get it here: http://www.mcumall.com/comersus/store/comersus_dynamicindex.asp It's also mentioned several times in the LinuxBIOS Wiki FAQ. It supports a large number of chips, each chip type requires a different DIP switch setting (see blue device in picture of above URI). Sincerely, Ken Fuchs <kfuchs(a)winternet.com>

While reading the Linux kernel off the hard drive? Do you get a crash, or is there just no output from the kernel? Are you sure you enabled serial console in your kernel parameters and while compiling the kernel? Stefan

[LinuxBIOS] VIA EPIA-ML6000EA VGA Problem and Kernel Panic
by Daniel Parthey 04 Feb '06

04 Feb '06

Dear List Members, I tried to get LinuxBIOS Rev 2163 running on an VIA EPIA-ML6000EA Board using the EPIA-M target. The kernel is on /dev/hda1 of an IDE harddisk. After building the rom image vgabios+linuxbios[filo] I did the following: Boot factory BIOS Remove BIOS chip Insert Test chip Write linuxbios.rom image to flash Reboot, it booted, network worked, but vga output failed Reboot, it booted, network worked, but vga output failed Switched off power Switched on power Graphic output totally fails and kernel panic occurs, my LinuxBIOS.rom does not boot on its own anymore. Maybe this has something to do with the VGA Bios, but I don't know what the reason could be? I extracted the VGA Bios from the running system with original BIOS with the following command and get an video.bios.bin with the 55 aa in the first two bytes: dd if=/dev/mem of=/video.bios.bin bs=65536 count=1 skip=12 At some other location I read something about other weird dd parameters. The resulting vga image from /dev/mem looked as follows: $ ls -l video.bios.bin -rw-r--r-- 1 pada pada 65536 2006-01-23 10:31 video.bios.bin $ file video.bios.bin video.bios.bin: BIOS (ia32) ROM Ext.

I hacked the Makefile to prepend vga.bios.bin to the bios image (as described in the VIA EPIA-M howto) Now I get a kernel panic with the following output on ttyS0 and the system hangs.

Perhaps the serial log of the boot, etc... There are not any "official" kernel patches as it all depends on what hardware you have and what you are trying to do. I don't use that hardware but in 99% of the cases the kernel crash is due to linuxbios not setting something up like the factory bios does. First you need to load a memtest payload and verify your RAM is working 100%. -- Richard A. Smith

[LinuxBIOS] Slow SATA on Tyan s2891 with LinuxBIOS
by Greg Johnson 02 Feb '06

We have noticed some performance issues with the nvidia sata controller under LinuxBIOS. With FB it is faster. Using "hdparm -Tt /dev/sda" we measure 30 MB/s with LB and 45 MB/s with FB on a particular node. lspci reports 0000:01:08.0 IDE interface: nVidia Corporation: Unknown device 0055 (rev a3) (prog-if 85 [Master SecO PriO]) with LB and 0000:00:08.0 IDE interface: nVidia Corporation: Unknown device 0055 (rev f3) (prog-if 85 [Master SecO PriO]) with FB. Also "hdparm -I /dev/sda" reports R/W multiple sector transfer: Max = 16 Current = 16 with FB and R/W multiple sector transfer: Max = 16 Current = 0 with LB. Any ideas about how to improve the SATA performance under LB? Thanks, Greg

-Linuxbios In my normal hunting of e-bay I found a nice embedded board for a good price, I just bought one :-) I do not think Linuxbios will be hard to port on to this board. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6845741668 -Adam
