[please cc: me since I am not subscribed on the list] Hi,
First, If this is the wrong list to discuss kexec, please tell me. It is hard to find any homepage or documentation about kexec in the web. I am trying to use kexec to run some X86 real-mode code from Linux. I tried to mimic a bzImage file, but although GRUB and ISOLINUX load it, kexec (the userland program from kexec-tools) does not like to load the image at all (I used the --real-mode switch but it did not help). [My aim is to to chainload another (non-free) OS by loading its boot sector into memory and executing it. Just like chainloader in GRUB, but from kexec.] Now I created a "hello world kernel" that just echoes "Hello world" using Int 0x10 BIOS function. That one shows the same behaviour. Works in GRUB, but not with kexec. I uploaded this "kernel" to http://home.arcor.de/mschierlm/test/hello.tar.gz if anyone wants to have a look at it. Is it just impossible to load real mode code with kexec? Or is another kernel format than bzImage more appropriate? Where do I find documentation for those other formats (if they may work better?) TIA for your help, Michael _______________________________________________ fastboot mailing list [email protected] https://lists.osdl.org/mailman/listinfo/fastboot
