If you |actually have a section table then yes the first entry needs to be a |dummy. All the same, even though I specified 0 for the number of section table entries and null for the offset, the tools went looking for a section table. Feel free to take this up with the BFD maintainers yourself, I'm not going to lose sleep over 32 bytes extra in the file. |1. convert_param.c |2. kernel |3. Ramdisk (optional) | |convert_param.c converts multiboot headers, and my redesigned headers, |holds the hard coded kernel parmeters. I use a little perl program |call mkelfImage to generate this. | |I don't currently have any 16 bit code, I start the linux |kernel in it's 32bit entry point. Etherboot doesn't have any 16 bit code either (except for the BIOS calls) when it's calling the extension in protected mode. The only 16 bit mode code is in boot.S and setup.S from the kernel. So it looks like you have all that you need already. I might even change the code to detect the multiboot magic number automatically and eliminate one more configure option. |
