Does the GRUB Installer Manually patch Stage1? I have parts of the code which would not work or which are buggy if values are not changed... is this what happens?

Yes, it does - of course, or you would have to edit your MBR manually after an install...

Well editing the MBR is practical enough, but for example the lines...
Code: Select all
boot_drive_check:
jmp 1f
testb $0x80, %dl
jnz 1f
movb $0x80, %dl
Apparently this code will not run on a floppy becasue of the first jump but will run through on a harddrive. Does the GRUB installer replace the first jump?
