RE: booting other oses

[Dave Aubin]

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

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)

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 ...

thats good to know.

I understand. so what is the preferred boot loader with linuxbios?
