I have a horrible feeling that you hit a bug caused by the renaming of the
ramdisk to memorydisk. You have three choices:

1) (not recommended) You can manually change the options on the bootloader as
per Mark Brinicombe's email of last night.

2) You can wait for Mark to put a new kernel/bootloader online and then use the
device md0 instead of rd0 as the root device.

3) You can download an old sa kernel and use that as advertised.

To label discs you need to boot off floppy/ramdisk. You will know when this is
working correctly because part way through bootup it will start reading the
floppy and tell you what percentage has been copied to ramdisk.

To boot initially (before you have labelled the drive) set the boot device to
either rd0 or md0 (depending on which kernel you have) and the ramdisk size to
1440K.

No. The first thing RiscBSD does when it boots is to throw away RiscOS.
