The installation process will copy the driver "P4_Flickerfixer" to the drawer "Devs:Monitors". This driver controls the Picasso IV on-board flicker fixer. The picture timing data the flicker fixer uses can be edited with "PicassoModeTNG" which will store this data in the icon of the P4_Flickerfixer driver. After starting the driver the timing parameters will be made memory resident, so they will survive a reboot; every time you open the boot menu ("Amiga early startup options") or boot from floppy disk the flicker fixer will be using the new picture timing parameters. However, if you switch off the Amiga these parameters will be lost. Before you can use them again, the P4_Flickerfixer driver must be started again.
