Bug#857597: debian-cd: "isolinux.bin missing or corrupt" when booting USB flash drive in old PC

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

the weekly testing ISOs for i386 and amd64 are now equipped with the
new MBR:

  https://cdimage.debian.org/mirror/cdimage/weekly-builds/i386/iso-cd/debian-testing-i386-netinst.iso
  https://cdimage.debian.org/mirror/cdimage/weekly-builds/amd64/iso-cd/debian-testing-amd64-netinst.iso

Testers wanted for booting this ISO from USB stick.

One can recognize the new MBR by the MD5 of bytes 32 to 431:

  $ dd if=debian-testing-i386-netinst.iso bs=1 skip=32 count=400 2>/dev/null | md5sum
  1705df1b3dee9b725432e099ecc63eaf  -

  $ dd if=isohdpfx.bin.170324 bs=1 skip=32 count=400 2>/dev/null | md5sum
  1705df1b3dee9b725432e099ecc63eaf  -

The old MBR, which caused this bug report, yields
  2b1369901086845791f595a9aa8b1a16


Have a nice day :)
