if the "BIOS boot part" at 34 - 2047 sector, and then it is just 1007.0 KiB. Number Start (sector) End (sector) Size Code Name 1 34 2047 1007.0 KiB EF02 2 2048 1361886 664.0 MiB 8300 vm1_part1 Althrough the first partion is not aligned, but it is just 1007.0 KiB. > > -- Bruce > -- > http://linuxfromscratch.org/mailman/listinfo/blfs-support > FAQ: http://www.linuxfromscratch.org/blfs/faq.html > Unsubscribe: See the above information page -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
