Unknown bootloader class !! error.......... what is this?

[gimyung han]

I finally succeed to load linux kernel image via etherboot............

but I encountered following error

Loading 192.168.0.1: 
/tftpboot/vmlinuz.epia...(ELF)..............................erhine disable

Unknown bootloader class !
type= 00000000
data= 0009882e
Firmware type: LinuxBIOS

it's all I got................

I made kernel image on the host computer( p4-2.65GHz, 512ddr)

Of course, its configuration is fit for my host computer.

Thanks for any help......................

This is from setup code of your ELF kernel, and it's not an error,
just a warning.

If you configure your kernel to have console on serial port
and give the command line like "console=ttyS0,115200"
to the kernel (at mkelfImage), you should see the messages from
kernel in addition to the above lines.

EPIA doesn't boot with kernel optimized for P4,
because C3 processor doesn't have CMOV instructions.
You should use a kernel compiled for C3.

did you load a kernel or an elfimage built from a kernel?

You are making good progress.

Oh, right, you should do this for your very first kernel:
- make it an i386, and turn off all features (mtrr, etc).
- turn off vga consoles
- enable console on serial port
