In a PC I have installed 7.0 . Then I have changed the PC ( or I have attached the hard disk to another PC ) . The mainboards were the same Intel DG965WH . but processors were different . In the new PC . FreeBSD could NOT be booted successfully . It locked during booting . Power disconnected and the PC re-powered could be booted in a new try but not in other tries . When I attached the hard disk to its original PC it continuously booted successfully . This means that during booting . FreeBSD is looking some values stored during installation ( for example : Signature of PC ) . When hard disk is attached to another PC and signature of new PC is different from the previous one , it is not booting successfully . Consequence of this is that when a USB hard disk is used then it will NOT be transportable to other PCs unless booting is made insensitive to such changes . I am also using Mandriva Linux Free 2008.0 . It is able to boot in different machines . During installation it is possible to make an install parameters diskette to store installation parameters and use this diskette for other installations to give installation parameters directly from diskette . Thank you very much . Mehmet Erol Sanliturk
