Hi; As a result of the ongoing GRUB discussion, I have been trying to trace the use of GRUB from BIOS to the end of GRUB stage 2. I am particularly interested in seeing how the MBR is used. I can create a temporary copy of my MBR using: # dd if=/dev/sdX of=/tmp/sda-mbr.bin bs=512 count=1 My question is; what program should I use to read this file in a human meaningful way (hexdump??)? I am trying to see how the MBR names partitions; and how GRUB uses those names. That is, are the partitions named in MBR actually named hd0,0 (ie the binary or hex equivalent of hd0,0) etc. or is there a further translation step required by GRUB? Does the device/partitioning system used by MBR and GRUB have a name(s)? (For Internet search purposes). I am interested in the hardware/software interface of booting. Is there anything additional I should know about this partition-locating process? -- Regards Bill
