| |
Hi!
The x86 bzImage contains a stub to inform people that it is not possible any more to run a Linux kernel by catting it to a floppy and then booting from it. This was meant to be all 16-bit code. The first instruction, however, ended up as being coded as a 16:32-bit far jump. I assume the intention was a 16:16-bit far jump.
This patch changes only i386.
Greetings, Alexander
