Well if the manufacturer wants a default of EFI, who am I to argue? :) Um, I grew up with BIOS (well really before BIOS, I go back to teletypes at 55 baud and GE Mark IVs and real Dartmouth BASIC), and EFI is 'new' to me.

I believe I can deal with the 11Gb 'waste' as I am moving from a 60Gb to a 320Gb drive and really not much into movies or such. -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
