The workaround to that issue is to not reset your prom. The proper
command in open firmware to set boot device is
setenv boot-device <elf image>
<elf image> defaults to 'hd:,\\:tbxi' when your prom is reset.
Generally this only happens when you have to do the emergency reset
procedure. If its happening during normal operation you've got a
problem program that's doing bad things.
When you reset, you'll need to redirect the boot-device variable to load
your ybin bootloader's elf image:
setenv boot-device hd:#,\\:tbxi
Where # is the number of your bootloader partition.
An alternative to this, if you want to avoid ever having to do that
again, is a procedure that's a little tricky and will require a lot of
effort (more than most people would consider worth it)
OF will, when it's boot-device environmental variable is set to
"hd:,\\:tbxi" without a partition number, incrementally search the
partitions on the primary harddrive for the ELF image ":tbxi". The
natural progression of this is to format your entire disk, run a Mac
partitioning tool on your HD. Then load up the YDL install disk, create
your bootloader parition, then load up the Mac installation disc, create
your Mac partition, install MacOS, then go back and install YDL.
Lots of work and I'm not absolutely sure that ybin would be able to, in
that case, load MacOS, possibily instead it simply does what OF does and
incrementally searches partitions for the default ELF image, recursively
loading itself. :)
Hope this is helpful. Remember to write down your bootloader partition
number, its important.
