[LinuxBIOS] Tyan S2850 VGA
by Jun OKAJIMA Nov. 10, 2005

Nov. 10, 2005

Hello. I am looking for M/B with these specs. 1. Boots fast (2 or 3 secs) with linuxbios ( or other utils). 2. Supports VGA, including X. 3. High performance. Like over 2GHz or such. How about S2850? it suppors VGA with X? Or, you know any other M/B? --- Okajima

[LinuxBIOS] Fast booting
by Jun OKAJIMA Nov. 10, 2005

Do you know any other fast boot solution than linuxbios? I tested Via fast boot util, but it is not so fast... For example, how about this. General Software Embedded BIOS http://www.gensw.com/pages/prod/firmbase/firmbase.htm --- Okajima, Jun. Tokyo, Japan.

[LinuxBIOS] VIA EPIA M10000 (Nehemiah) CentaurHauls Stepping 5 support status
by tristan Nov. 10, 2005

Nov. 10, 2005

Hi list, I'd like to know the exact support status of LinuxBIOS on VIA EPIA M10000 (Nehemiah) CentaurHauls Stepping 5. I've seen messages (August 2005) that say VGA is supported, and more recent threads that say it isn't. So, what is supported by the mainstream LinuxBios v2 ? And what is not yet? Are these any patches around that could achieve better support? All different messages I see are rather confusing ... Another question: VIA has published a "FastBoot" BIOS that seems to be a fork of LinuxBIOS, since it's a fork and LinuxBIOS is covered by GPL, is FastBoot a GPL violation? Someone has ever had the sources of FastBoot? If ever, could it lead to a better support of EPIA motherboards? Thanks for you answers, Tristan

[LinuxBIOS] Build broken?

Nov. 10, 2005

Hi, I download a lateset snapshot from linuxBIOS.org yesterday. I don't know if it is bad luck or something, I can not successfully build any BIOS from the tree I downloaded. I tried following three platform. tyan/s2891 tyan/s2895 amd/serenade Does anybody has similar issue or know what happened? Below are the details on the things I got for these three different target platform 1. Both tyan/s2891 and tyan/s2895 have similar behavior I changed a few lines in Options.lb: default USE_DCACHE_RAM=1 default CONFIG_USE_INIT=1 default DEFAULT_CONSOLE_LOGLEVEL=7 default MAXIMUM_CONSOLE_LOGLEVEL=7 I get a error output like below: (Note: Changing options in the Options.lb above were not the cuase of the problem. Without changing USE_DCACHE_RAM and CONFIG_USE_INIT, I still get same results) ------------ gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /export/1/new/src/config/linuxbios_ram.ld linuxbios_ram.o linuxbios_ram.o(.text+0x13db9): In function `smp_write_config_table': : undefined reference to `get_apicid_base' collect2: ld returned 1 exit status make[1]: *** [linuxbios_ram] Error 1 make[1]: Leaving directory `/export/1/new/targets/tyan/s2895/s2895/normal' make: *** [normal/linuxbios.rom] Error 1 2. amd/serenade gets the build error like below. It probably is the side product of the tree enabled dual core and cache as RAM? ----- gcc -m32 -nostdlib -nostartfiles -static -o linuxbios_ram -T /export/1/new/src/config/linuxbios_ram.ld linuxbios_ram.o linuxbios_ram.o(.text+0x14d2): In function `model_fxx_init': : undefined reference to `get_node_core_id' linuxbios_ram.o(.text+0x14e6): In function `model_fxx_init': : undefined reference to `amd_sibling_init' collect2: ld returned 1 exit status make[1]: *** [linuxbios_ram] Error 1 make[1]: Leaving directory `/export/1/new/targets/amd/serenade/serenade/normal' make: *** [normal/linuxbios.rom] Error 1 Any help would be appriciated.

Where do I find information on booting "tiny kernel"? Or could you guys explain it to me? Thanks, Matt

Re: [LinuxBIOS] [Etherboot-developers] Infiniband driver
by Lu, Yinghai Nov. 9, 2005

Nov. 9, 2005

Who want it? LinuxBIOS, current System BIOS or EFI? For LinuxBIOS, We will use LinuxBIOS+tiny kernel for booting. The Tiny kernel could include IB and IP over IB, So we don't need to port driver from kernel to everywhere....

In our plans is a to add support for a second line of devices. This will allow a host having an HCA to use it for doing remote boot. It is based on Etherboot and we would like to open the source to the public and we would like it to be part of Etherboot. I would like to know how to move in this direction.

The elf image is found but failed to load properly. I believe the size is embedded in the elf segment. If your sizes were all wrong I would expect that it either wouldn't boot or it would not find the payload. Are you using XIP? If so you might try turning it off. You will probally have to go look in the elf load code and see what causes that message I've not looked at the elf load code so I don't have many suggestions. Is you adlo.elf really a valid elf image? What do you get for a 'readelf -a adlo.elf' -- Richard A. Smith

[LinuxBIOS] ADLO with EPIA-M LX2
by Anton Borisov Nov. 9, 2005

Nov. 9, 2005

Hi. I have compiled ADLO from LX1 (freebios--devel--1.0--base-0.tar.bz2). Pure BOCHS BIOS ~58k. Payload with VGABIOS - 124k. My Config.lb is below: = target epia-m mainboard via/epia-m option MAXIMUM_CONSOLE_LOGLEVEL=8 option DEFAULT_CONSOLE_LOGLEVEL=8 option CONFIG_CONSOLE_SERIAL8250=1 option ROM_SIZE=256*1024 option HAVE_OPTION_TABLE=1 option CONFIG_ROM_STREAM=1 option HAVE_FALLBACK_BOOT=1 option FALLBACK_SIZE=0x30000 option _RAMBASE=0x00004000 romimage "fallback" option USE_FALLBACK_IMAGE=1 option ROM_IMAGE_SIZE=0x10000 option ROM_SECTION_OFFSET=0x10000 option ROM_SECTION_SIZE=0x30000 option LINUXBIOS_EXTRA_VERSION=".0Fallback" payload /home/anthony/src/payloads/adlo.elf end buildrom ./linuxbios.rom ROM_SIZE "fallback" = Some comments regarding FALLBACK_SIZE. This is done intentionally to include VIA's VGABIOS into fallback portion. linuxbios.rom being composed this way is written into flash chip. Unfortunately I wasn't able to load ADLO payload (see messages below). = Moving GDT to 0x500...ok Wrote linuxbios table at: 00000530 - 00000b28 checksum 97d3 Welcome to elfboot, the open sourced starter. January 2002, Eric Biederman. Version 1.3 33:stream_init() - rom_stream: 0xfffd0000 - 0xfffeffff Found ELF candiate at offset 0 Cannot Load ELF Image = I assume this is a problem with improper configuring ROM_IMAGE_SIZE, ROM_SECTION_OFFSET in my example. I did increase it to 0x20000 value. And I've got this error while compiling with ROMCC: = ./romcc -mcpu=c3 -O -I/home/lx/src/LinuxBIOSv2-2080/src -I. -I/home/lx/src/LinuxBIOSv2-earlymtrr.c:21.45: Integer constant to large = Where I've done wrong? Does anybody experienced with ADLO applying to LX2 recently? Thanks. -- Sincerely, Anton Borisov
