Oh, I should say that it does _execute_ the boot-script, but I don't know if it's properly handled by the Forth interpreter. Any idea what the boot-script you cite is supposed to actually _do_ (I gave up trying to read Forth at around 3 AM last night)? > > In Panther Install CD, BootX is: > > > > MacRISC MacRISC3 MacRISC4 > > > Boot Loader for Mac OS X. > > > > > ... > > load-base > begin > =A0dup 6 " </CHRP" $=3D if > =A06 + dup 6 " -BOOT>" $=3D if > =A0 8 + true > =A0else > =A0 false > =A0then > =A0else > =A01+ false > =A0then > until > ( xcoff-base ) > load-size over load-base - - > ( xcoff-base xcoff-size ) > load-base swap move > init-program go > > > [...XCOFF HERE] > > > Regards, > Laurent > > > -- > OpenBIOS =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 http://openbios.org/ > Mailinglist: =A0http://lists.openbios.org/mailman/listinfo > Free your System - May the Forth be with you
