Sorry - you didn't need to read the whole email chain. My goal is to make the bios code accessible to more developers. The current code is, IMO, not maintainable. (It has over 11,000 lines of code in one file, and it is a random mix of C and assembler.) My interest is with the coreboot project - to get a bios running on real hardware. In order for that to work, more developers will need to be able to test, author, and debug code in the bios. As to C vs Assembler - the existing code has plenty of C code. It also has plenty of assembler, but I think what was made assembler was purely arbitrary. Plenty of code paths that have no performance (or stack) implications are written in asm. Other paths, that clearly are sensitive are written in C. In particular, the code we've been discussing (int 13) was written in C in bochs bios. -Kevin ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Register now and save $200.
