I'm puzzled by the 2nd one... what does he mean by 'Cannot find > map file'? I guess he means that he can't find the /boot/map file, No, its looking for a System.map file, which lists where all the functions live when the kernel is in memory. (useful for debugging kernel panics among other things). > > but > it's there (together with a boot.0300 and a boot.0302 - btw, what are > those files anyway?) Is it somehow serious or dangerous for the system? /boot/boot.0300 is a backup of the boot sector for the master boot record of /dev/hda. /boot/boot.0302 would be a backup of the partition boot record of /dev/hda2. (ls -l /dev/hda shows that hda is major device 3, minor device 0; ls -l /dev/hda2 shows that hda2 is major device 3, minor device 2) > > A bit later, when setting up the serial ports, it states: > > Aug 18 16:45:27 groo kernel: Serial driver version 4.27 with no serial > options enabled > Aug 18 16:45:27 groo kernel: ttyS00 at 0x03f8 (irq = 4) is a 16450 > Aug 18 16:45:27 groo kernel: ttyS03 at 0x02e8 (irq = 3) is a 16450 > > OK... whay ttyS00 and not ttyS0??

Looking at the source in drivers/block/floppy.c, it has something to do with seeking and getting high transfer rates (128k/s) on special floppy drive controllers. > > Thanks for your attention!!!
