Hi, I finally uploaded a draft (not to be merged yet -- the patch needs to be split in nicer chunks!): https://github.com/bartoldeman/fdkernel/commits/ia16-elf-gcc-draft patch can be seen here: https://github.com/bartoldeman/fdkernel/commit/f873f2052e83fedadfd10b04d79d07246da30bbd

Indeed, less free memory, somewhat bigger kernel.sys file for those who still deal with floppies. Though it's improving, already 2.5k smaller than last time I wrote. >> Alternatively said: ia16-elf-gcc and binutils does not support OMF, >> only ELF, and therefore NO segment relocations, as ELF is flat. > > You mean even ELF (with 8-bit extensions) isn't fully supporting all > features?

But it can work a little more cleanly than before with ELF using a linker script and explicit segments ie. instead of "jmp far symbol", had to do "jmp DGROUP:symbol" etc. > FYI, NASM is still cross-compiled via DJGPP for DOS with official > binaries (e.g. 2.13.01).

So far I have only cross-compiled from Linux, so I've ignored all things DJGPP. It would be nice to be able to do the compilation natively on DOS eventually though it's not my priority.
