The fact is, the linux kernel is just about the best thing you can use to boot another kernel! Dave, think about this: are you planning to write etherboot drivers for myrinet, quadrics, infiniband, SCI, or other new networks? How about all those ugly, complicated SCSI disk systems? If yes, you're nuts and you are going to duplicate a lot of work that Linux does better. If no, then etherboot can't even be used on our 1024-node Pink cluster (which has no Ethernet, only myrinet). Another weird thing we've found: Linux, on faster machines with lots of network interfaces in them, boots nodes faster than etherboot! weird but true. I think you are not looking at a big enough picture. Etherboot is fine for a lot of cases, but if you can put Linux in flash, it's a LOT better, and as the processors get faster, Linux is faster too. ron

It should be Flash Rom? That's very interesting. Can you let me know how to build such small kernel and initrd?

The kernel and initrd are munged together with mkelfimage. Voila ... kernel boots in seconds. ron

Ron, So any instructions to use kernel in flash. 1. I guess use filo to load the elf ( the elf will be in flash, and filo will be in the ROM) 2. the elf is made by mkelfImage from Kernel and ramdisk. How can the kernel load another kerkel, via beoboot????

booting other oses
by Jakob Praher 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!

vgainit.inc halt epia
by zhu shi song 24 Aug '04

24 Aug '04

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
