I tried installing the latest 2.1 iso on an Intel MFSYS25 with dual storage controllers and get the following error:

isolinux: disk error 20, AX =42bb, drive EF


I seem to recall having similar problems with the 1.8 iso and in this case I installed from a previous version iso and then upgraded to 1.8.

Not sure how to proceed in this case

do you see this only on dual storage controller systems?

I have not tried it on single storage controller units. After posting this I was getting more and more problems with the server module I was trying to boot the iso with , so it may just be that the server module is bad. I will post back once I get the module fixed/replaced.
 
Ok I just downloaded the 2.0 iso and this one works fine. After I installed 2.0 I tried the 2.1 iso again and it also worked. Is there any difference between the 2.0 and 2.1 as far as the installation environment is concerned. 2.1 failed to install on a initialized raw drive but did work on formatted partitioned drive.
 
I have been trying to install VE 2.1 or 2.0 on another server module with no luck. Bot using the 2.0 and 2.1 iso images.

I even removed one storage controller to see if this was causing the problem. I continue either get:

isolinux: Disk error 20, Ax =421D, drive EF


or the installation will go through but the system will not boot, just get a cursor.

I am not sure if it is the iso installer or the Flex server (Tom have you installed 2.1 on the Intel flex server?)

Very frustrating day today!

Booting from USB stick worked perfectly!! Seems with the latest firmware update on the Intel Modular Flex Server MFSYS25 the iso and cd-rom redirect does not work very well anymore. I have submitted a report to INTEL and will also update the Wiki to let PVE users know to use USB boot method on MFSYS systems instead or ISO or cdROM.
