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

[David Christensen <dpchrist@holgerdanske.com>]

syslinux at zytor.com:

I have two older computers with Intel D865GBFLK motherboards (~2003)
and Pentium 4 HT CPU's.  They both have the latest available BIOS
installed.  I would like to put Debian on them.


I have downloaded:


http://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-8.7.1-i386-xfce-CD-1.iso


When I put debian-8.7.1-i386-xfce-CD-1.iso on a CD-R, it boots correctly.


When I put debian-8.7.1-i386-xfce-CD-1.iso on a USB flash drive and boot 
it, I see the following on the console:

    isolinux.bin missing or corrupt


The same USB flash drive boots correctly in newer computers.


Memtest86+ 5.01 on a USB flash drive boots correctly in the older
computers:

    http://www.memtest.org/download/5.01/memtest86+-5.01.iso.gz


My conclusion is that debian-8.7.1-i386-xfce-CD-1.iso, when put on a USB 
flash drive, is not compatible with the BIOS in the older computers.


I have filed a Debian bug report, and have been advised to post here:

Please advise.


TIA,
