Hi, This is interesting. I wrote some newer documentation for PXE booting here: http://www.freebsd.org/doc/handbook/network-pxe-nfs.html In 32.8.4, bullet item 1, I mentioned that it is necessary to configure network booting in the BIOS menu. With your change, is entering the BIOS menu to configure network booting still necessary? -- Craig Rodrigues rodrigc@juniper.net On Thu, Dec 15, 2011 at 1:21 PM, Andrew Boyer <aboyer@averesystems.com> wro= te: > These two changes allow you to set PXE as the default MBR boot selection,= which enables you to write a 'reboot to the network' script. =A0We've foun= d it to be very useful. =A0What do people think? > > Thanks, > Andrew > >> Index: usr.sbin/boot0cfg/boot0cfg.c >> =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D >> --- usr.sbin/boot0cfg/boot0cfg.c =A0 =A0 =A0(revision 228359) >> +++ usr.sbin/boot0cfg/boot0cfg.c =A0 =A0 =A0(working copy) >> @@ -169,7 +169,7 @@ >> =A0 =A0 =A0 =A0 =A0 =A0 o_flag =3D 1; >> =A0 =A0 =A0 =A0 =A0 =A0 break; >> =A0 =A0 =A0 =A0 case 's': >> - =A0 =A0 =A0 =A0 =A0 =A0s_arg =3D argtoi(optarg, 1, 5, 's'); >> + =A0 =A0 =A0 =A0 =A0 =A0s_arg =3D argtoi(optarg, 1, 6, 's'); >> =A0 =A0 =A0 =A0 =A0 =A0 break; >> =A0 =A0 =A0 =A0 case 't': >> =A0 =A0 =A0 =A0 =A0 =A0 t_arg =3D argtoi(optarg, 1, 0xffff, 't'); >> @@ -472,6 +472,8 @@ >> =A0 =A0 printf("default_selection=3DF%d (", mbr[OFF_OPT] + 1); >> =A0 =A0 if (mbr[OFF_OPT] < 4) >> =A0 =A0 =A0 printf("Slice %d", mbr[OFF_OPT] + 1); >> + =A0 =A0else if (mbr[OFF_OPT] =3D=3D 5) >> + =A0 =A0 =A0 =A0print("PXE"); >> =A0 =A0 else >> =A0 =A0 =A0 printf("Drive 1"); >> =A0 =A0 printf(")\n"); >> Index: sys/boot/i386/boot0/boot0.S >> =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D >> --- sys/boot/i386/boot0/boot0.S =A0 =A0 =A0 (revision 228359) >> +++ sys/boot/i386/boot0/boot0.S =A0 =A0 =A0 (working copy) >> @@ -413,6 +413,7 @@ >> =A0 =A0 =A0 3: >> #endif /* ONLY_F_KEYS */ >> #endif /* SIO */ >> +check_selection: >> =A0 =A0 =A0 =A0 =A0 =A0 =A0 cmpb $0x5,%al =A0 =A0 =A0 =A0 =A0 =A0 =A0 = =A0 =A0 # F1..F6 or 1..6 ? >> #ifdef PXE /* enable PXE/INT18 using F6 */ >> =A0 =A0 =A0 =A0 =A0 =A0 =A0 jne 1f; >> @@ -421,7 +422,6 @@ >> #endif /* PXE */ >> =A0 =A0 =A0 =A0 =A0 =A0 =A0 jae beep =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0= =A0 =A0 =A0# Not in F1..F5, beep >> >> -check_selection: >> =A0 =A0 =A0 /* >> =A0 =A0 =A0 =A0* We have a selection. =A0If it's a bad selection go back= to complain. >> =A0 =A0 =A0 =A0* The bits in MNUOPT were set when the options were print= ed. > > -------------------------------------------------- > Andrew Boyer =A0 =A0aboyer@averesystems.com > > > > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org= " --=20 Craig Rodrigues rodrigc@crodrigues.org
