Intrebare pentru cunoscatori: FreeBSD 5.x vine compilat pentru 386 sau o o fi optimizat pentru procesoare mai recente?
386. Iti vine cu un kernel generic care nu e compilat cu optiuni speciale in gcc (poate cel mult -O2) tocmai ca sa nu te lase cu ochii in soare cand vrei sa-l pornesti si pe masini mai vechi.
Ei bine chestia asta era valabila pina pe la branch-ul 5.x. Pe linia 5.x deja s-a renuntat la compatibilitatea NUMAI cu CPU 386 din ratiuni de performanta si sunt valabile urmatoarele (citez din /usr/src/UPDATING):
20010116:
The kernel option I386_CPU is now mutually exclusive with the
other cpu types. If you have an i386 system, be sure that it
only had this line. Remove it for all other configurations.20030722:
FPU-less support has been removed from FreeBSD. Chances are you won't
notice. 386+387 support should still work after this change, but
it is now a minimum requirement for the i386 port that you have real
FPU hardware.
Si ca sa fie toate lucrurile clare, citez si din FreeBSD Handbook, sectiunea "Configuring the FreeBSD Kernel":
Support for I386_CPU is still provided in the source of FreeBSD, but it is disabled by default in both -STABLE and -CURRENT. This means that to install FreeBSD with a 386-class cpu, you now have the following options:
o Install an older FreeBSD release and rebuild from source as described in Section 9.3.
o Build the userland and kernel on a newer machine and install on the 386 using the precompiled /usr/obj files (see Section 21.5 for details).
o Roll your own release of FreeBSD which includes I386_CPU support in the kernels of the installation CD-ROM.
The first of these options is probably the easiest of all, but you will need a lot of disk space on a 386-class machine which may be difficult to find (Nota mea: dar nimeni nu va impiedica sa montati in retea o partitie prin NFS).
