"isolinux.bin missing or corrupt" when booting USB flash drive in old PC
...unpacked in a suitable directory by

The binary "block_seq" was compiled on Debian Jessie.
If it does not run, do
cc -o block_seq block_seq.c
to get a locally compiled binary.
When Martin posted his MBR binary, the test stick shall be composed by:
dd if=martins_mbr.bin bs=1 count=432 of=/dev/sdc
dd if=debian-8.7.1-i386-xfce-CD-1.iso bs=1 count=80 seek=432 of=/dev/sdc
./block_seq | dd bs=512 skip=1 count=1325055 seek=1 of=/dev/sdc

...lock_seq
by omitting dd option count=647 ?
/home/dpchrist/sandbox/syslinux/thomas-schmitt/block_seq-20170321-0141/block
