I write this to the kernel mailing list, because my question couldn't be answered on irc (eg. irc.kernelnewbie.org): ____________________________________________________________________________ arch/i386/boot/setup.S:
164 trampoline: call start_of_setup 165 .space 1024 166 # End of setup header ##################################################### 167 168 start_of_setup: 169 # Bootlin depends on this being done early 170 movw $0x01500, %ax ____________________________________________________________________________ my questions are:
-) Why is there a call on line 164 and not a jmp? -) Why does line 165 reserve 1024 bytes? what is it for? -) On line 170: Why $0x01500 and not $0x1500?
I would appreciate if someone could answer this mail, or if someone can provide ressources where I can find detailed description of the kernel code (didn't find anything, just overall information)
regards,
andy
