That is doable. Would the bios drive order translation account for the slowness of the F12 system? It is intolerably slow when multitasking, often taking 30 seconds to a minute to close a window if the package manager is also running. Launching another app from the menu, which takes 5 seconds to display, often exceeds the busy cursor timeout, so one is surprised when that apps window is suddenly drawn 2 or 3 minutes later. OTOH, since its a new install, I could just as easily do a reinstall. What sort of a voodoo spell to I have to use to get a /boot partition of say 400 megabytes? The default is only 100, and that will never fly here for more than a week. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
