This worked!

However the loadbsd options do confuse me a bit ...

loadbsd [-abhkpstADSVZ] [-c machine] [-m mem] [-n flags] [-I sync-inhibit] 
kernel

"-ASn2" actually shouldn't work because "-n" is split from "-AS". I
would do it "-AS -n2". Why does "-ASn2" work?

I tried to applied the same (to me, non-understandable rule) with
"-I". There -ASn2I0xffffff" doesn't work. I have to use "-AS -n2
-I0xffffff".

That's already quite interesting, but the best part comes now:
"-aSI0xffffffn2" doesn't work with loadbsd
"-aSI0xffffffn2" works while compiled into the bootblock ?!?!

Can someone explain this logic?

Another issue - I have 128 MB CSPPC FastRAM and 16 MB ZIP onboard
A3000 FastRAM.
- I guess the option to use is "-n2"?
- What does "-n1" do?
- Has the "-n" option any impact on ChipRAM?

Ignatios ... I found a directory called "ppcboot". What's that about?

"sh ./installboot /usr/mdec/xxboot /dev/rsd1a" worked!

Why is single user operation necessary?

Ok.

Thanks a lot!
