Subject: Etherboot and Linuxbios

Etherboot version used: 5.3.11

I am trying to build a Etherboot image to work with Linuxbios but got a
compile error. There are couple undefined references to some functions
due to the settings in the Config file.

I commented out the PCBIOS option, and define the following.

-DLINUXBIOS -DCONFIG_TSC_CURRTICKS  -DCONSOLE_SERIAL -DCOMCONSOLE=0x3f8
-DCOMPRESERVE -DCONFIG_PCI_DIRECT -DELF_IMAGE

-DPXE_IMAGE -DPXE_EXPORT

p.s The undefined reference is due to the undefined PCBIOS.

Etherboot and Linuxbios

[Gin]

Now my linuxbios found the ELF file created by Etherboot and tried to
jump to it. But it hangs afterward.

This is the debug output from linuxbios. It loads 2 seg from the ELF
file. But in a objdump on the ELF file. There is only one seg and the
loading addr is different.
