The file boot.0800 appears to be a backup of the MBR bootloader code and I bet it is 512B in size. It reflects dev with major number 08 and minor number 00, e.g. /dev/hda1, or /dev/sda1. I would also bet this was created by LILO, which is polite enough to back up the existing MBR before dumping its own code in the first sector of a hard disk. Characteristically, MSWindows is not that accommodating for other persons' bootloader codes.
