No. My G3 could never boot by these commands and "boot" command.
The results were always "CAN'T OPEN ide/disk@0:0".
The reason I thought the nvramrc contained something important was that "boo
t scsi-int/sd@0:0" returned "no bootable HFS partition" on my G3. This means
OF at least tried to boot from the internal SCSI drive. But "boot ide/disk@0
:0" seemed to have no effects on the IDE drive. So I guessed something was l
acking before typing "boot ide/disk@0:0", i.e. something to recognize the ex
istence of the IDE drive.

I also don't know Forth language well, but I presume these may contain the c
odes which enable atapi devices.
