Hi All,

It is impossible to boot Linux-based ISOs that use Syslinux 6.02 via CD or
DVD on older - non-UEFI - systems. Any attempt to do so will result in the
following error message: ISOLINUX 6.02 ETCDisolinux: Disk error 01, AX =
4279, drive FE

It is still possible to boot / install via USB data-stick, and in a Virtual
Machine. Where using a newer PC with UEFI, even in Legacy mode (and with
the UEFI partition completely removed), ISOs using Syslinux 6.02 will still
go through the UEFI menu.

I also noticed that (at least some) OSs not using syslinux 6.02 won't
recognise ISOs that do. For example, the file managers of Mint 13, Windows
7, and Windows 8 all wrongly "see" blank discs).

As a consequence, I am aware that the Manjaro Linux team have reverted to
using syslinux 4 for their ISOs.

This is certainly not an issue with corrupted downloads, burning, or dodgy
computer disc-drives.

Best Wishes,
Carl Duff
