[syslinux] isolinux: Disk error 20, AX=425 c, drive EF

[Bill E. Carroll]

Hello SYSLINUX,

    I have been searching for a resource for the "Disk error" messages 
coming out of isolinux.

    I am seeing the message "isolinux: Disk error 20, AX=425 c, drive 
EF" on many occasions where a combination of questionable Linux OS media 
comes in contact with touchy LITE-ON DVD/RW Drives attempting to load 
Red Hat Linux. We know that changing the Drive or the media solves the 
problem, but the drive and the media works in other workstations.

    I am an engineer working for the National Weather Service, and this 
is an issue that can potentially affect the workstations that 
Meteorologist use to view weather images on.

    I would be glad to share more information about this with you if you 
like. I very much appreciate any guidance you can provide.

Thanks,
