I'm using a fairly old version of V1 (July or so) and when I have an etherboot ebi payload and build linuxbios with gcc 3.2.3 linuxbios fails, whereas an older gcc 2.96 works.
It gets to the part where it is going to load/launch the payload. Here is what it does when it works, linuxbios built with gcc 2.96: Wrote linuxbios table at: 00000500 - 00000674 checksum ea53

--------------- The payload is the same in both cases. The filesizes are different by 0x200 bytes. My guess is it is something in elfboot. I remember reading something about the -fno-merge-constants option which might apply--older XFree86 servers have an ELF loader that doesn't like the new default behaviour of gcc and you have to turn this option to get their elf loading to work again.
This is probably something that has been hashed out already, sorry about that.
Any advice would be welcome.
