My bad, I messed up and used mkelfImage-1.6 that I got from
ftp.lnxi.com, when I realized that I ought to use the one from
freebios/util everything started working.
Here's what I did to get LinuxBIOS + Etherboot loading and booting a
Linux kernel using TFTP.
/Christer
Get etherboot-5.0 from the CVS tree on etherboot.sourceforge.net.
Modify etherboot-5.0/src/Config, comment out:
# BIOS select don't change unless you know what you are doing
#CFLAGS32+= -DPCBIOS
and uncomment the following:
# Options to make a version of Etherboot that will work under linuxBIOS.
CFLAGS32+= -DLINUXBIOS -DCONFIG_TSC_CURRTICKS -DCONSOLE_SERIAL -DCOMCONSOLE=0x3f8
-DCOMPRESERVE -DCONFIG_PCI_DIRECT -DELF_IMAGE
Compile Etherboot to make an elf file for your ethernet card:
make bin32/natsemi.elf
Compile and install mkelfImage from freebios/util/mkelfImage.
Create a bootimage to put on your TFTP server:
mkelfImage --command-line="root=/dev/hda2 console=ttyS0,38400" \
--kernel vmlinux -o /tftpboot/kernel
Finally, make sure that your BOOT/DCHP server is answering and that
the TFTP server is active.
Tell LinuxBIOS to boot an elf Image, and tell LinuxBIOS where it is:
option USE_ELF_BOOT=1
option ZKERNEL_START=0xfffe0000
option ZKERNEL_MASK=0xffff
I have placed natsemi.elf in the first 64k of my BIOS flash
chip, and LinuxBIOS in the second 64k.
insmod bios.o
dd if=natsemi.elf of=/dev/bios bs=64k
dd if=linuxbios.rom of=/dev/bios bs=64k seek=1
Finally boot LinuxBIOS.
