booting other oses
by Jakob Praher 25 Aug '04

25 Aug '04

hi all, how/where does linuxbios do the loading of other oses? linuxbios loads the linux kernel from the flashrom, which then it is in real mode imho. so does it use lobos/two kernel monte or something other way to load another app? I would apprieciate source code pointers or other directions where I can look for. for instance how would linuxbios boot into for instance grub or lilo? thanks --Jakob

Hi Stefan, What is your goal to want to use Linux bios? If your goal is to get It to load a Linux kernel, then try etherboot. There is also etherboot With filo. Etherboot will provide an elf file for you that is network Card aware and also has support for ide hd access. There is also a flavor Of etherboot that has filo support in it. Filo gives the ability to load Off of a usb stick. Knowing this you can use the net, ide drive or usb stick To load your os. Gotta love it;) Dave -----Original Message----- From: linuxbios-admin(a)clustermatic.org [mailto:linuxbios-admin@clustermatic.org] On Behalf Of Jakob Praher Sent: Wednesday, August 25, 2004 6:50 AM To: linuxbios Subject: Re: booting other oses hi Stefan, thanks für the info. I have included some additional questions. but lets summarize what I think I know: linuxbios is a bootstrapper thats able to load a linux kernel/elf binary from within a flash rom/file/...? or is linuxbios itself a linux kernel that is able to execute another elf binary? if the first option is true, it would probably need hardware access code for accessing ide/scsi disks without the 16bit callbacks (INT13 and friends) Am Mit, den 25.08.2004 schrieb Stefan Reinauer um 11:26: > * Jakob Praher <jpraher(a)yahoo.de> [040825 09:31]: > > how/where does linuxbios do the loading of other oses? > > LinuxBIOS can load an arbitrary static ELF binary from flash or disk. how do you then be able to load ntldr or something like that? afaik ntldr is no elf executable it is either a COFF/PE or it is a DOS exe ... > > > linuxbios loads the linux kernel from the flashrom, which then it is > > in real mode imho. > > It can also load a bootloader from flash, like etherboot, filo or > start openbios.

EPIA VGA and keyboard fail when booting from V2 linuxbios
by zhu shi song 24 Aug '04

24 Aug '04

I have boot my epia board successfully using V2 Linuxbios. I can see filo loading linux kernel to boot..But there are some problems: (1)keyboard fail (2)vga fail (3)my kernel boot fail, I can't see any prompt message from serial. How can I configure my kernel to support serial output? tks zhu __________________________________ Do you Yahoo!? Yahoo!

Q1: (1)freebios v1 (2)MB: epia (3)Kernel: 2.4.26 (4)I try to turn vga on following the steps in EPIA howto. But MB halt on executing vgainit.inc. Q2: (1)freebios V2 (2)MB: epia (3)kernel: 2.4.26 (4)I can boot filo from IDE CF, when jump to linux, I can't see any messages from vga or serial. (5)keyboard and vga are all off. It's hard for me to see how the kernel worked. zhu _______________________________ Do you Yahoo!? Express yourself with Y! Messenger! Free. Download now. http://messenger.yahoo.com

Hi, I see this chipset is in freebios, but not freebios2. I've been out of the loop for a while. Can anyone give me some current status info on this board/chipset? I see it listed as "unstable" Regards, Jeremy -- Jeremy Jackson Coplanar Networks (519)897-1516 http://www.coplanar.net

Panasonic CF-25LJM8EAM Toughbook - what are the chances?

I bought a Pansonic CF-25LJM8EAM notebook. All important chips on the mainboard are listed here: http://www.miernik.ctnet.pl/linuxbios/CF-25LJM8EAM-chiplist Bari, can you spot which one is the "keyboard controller" which you said is usually the critical problem on getting LinuxBIOS to a laptop?

The BIOS flash is unfortunately soldered, but I thing of giving the mainboard to an electronics facility so they can desolder it and solder a socket there. Interesting, the CPU is in a socket, so it might be possible to mount a AMD K6-2 350 MHz. It is possible on other Intel 430TX motherboards after binary patching the BIOS.

Opteron / Tyan motherboard fault on boot.
by Dave Belfer-Shevett 20 Aug '04

20 Aug '04

We're in the process of deploying Linuxbios to boot a cluster of Opteron based blade servers. I built a new kernel, put it in /tftpboot after using: mkelf-linux --rootdir=rom --ip=rom ./bzImage > vmlinuz.tyan and cycled the blade. Wen booting, I get: Searching for server (DHCP) Me: 192.168.1.200, Server: 192.168.1.200, Gateway 192.168.1.1 Loading 192.168.1.200:vmlinuz.tyan (ELF)... done LinuxBIOS-1.1.62.0_Fallback [date date] starting... Unknown Trwt Looking at an old message to this list, there's this snippet: http://www.mail-archive.com/linuxbios@clustermatic.org/msg03174.html where the following line(s) are, in set_Trwt()... if ((clocks < DTH_TRWT_MIN) || (clocks > DTH_TRWT_MAX)) { die("Unknown Trwt"); } What is this, and why is it happening? Is there a patch needed for LinuxBIOS to work properly on modern Opterons? Thanks, I'm in dire straights here, any help would be appreciated. -dbs -- -------------------. .----------- Dave Belfer-Shevett \ Conference Management Solutions \ Stonekeep dbs(a)stonekeep.com \ http://www.stonekeep.com \ Consulting ---------------------' 978 239 5902 `------------

In the Etherboot Src/arch/i386/Config There is an option -DCOFIG_X86_64. You need to enable it to use Etherboot boot elf with X86-64 kernel.

Stefan already gave the practical explanation. The small bit beyond that is the x86_64 kernel does not even have a valid 64bit entry point. The code is actually present in the 32bit etherboot to cope with an 64bit in for x86_64. But except for test programs I have not been able to find any native ones.
