I was trying to install eCS 2.1 with AHCI mode and I found that it takes a time to load GRADPANO.SYS while it boots for the installation procedure.
Any idea what does this driver does?
I suspect it's a GRADD back end for Panorama.
Not in all cases is the last device driver the cause of the hang of the system/delay of loading the system.
This is rather caused by the USB drivers in most cases. Disable the USB drivers in the preboot menu and it will load quickly again the system.
In 2.1 we did not include the USB drivers from Lars Erdmann because the host controller drivers are still under heavy development.
