Sorry for the earlier half finished post... should know by now that tab does
not work in Yahoo's mail editor the same as it does in most email packages :-(

Looking at the patch for the Linux kernel, that seems to be easy. They insert
the following code at the beginning of the image (head.S for Linux):

start:
        bl      start_
        nop
        nop
        .long   0x33
        .string "XncdPPC"
        .long   0x7fae0000
        .long   0x00413d80
        .long   0x00092214
        .long   0x00000000
        .long   0x39771c2a
        .long   0x00000010
start_:

My plan was to try the same thing with a PREP NetBSD kernel (the patch I have
for Linux is on top of their PREP kernel, so that seemed like a good starting
point for NetBSD as well). I have no idea what any of that means, and I cannot
find any information about how it was derived. It is similar to, though not the
same as the beginning of the text section in the IBM image I have:

     b       0x8101200c
     nop
     nop
     .long   0x33
     .string "XncdPPC"
     .long   0xf3920000
     .long   0x00413a80
     .long   0x81012d64
     .long   0x00000000
     .long   0x39771b37
     .long   0x23

I'll let you know how I get on - the PREP kernel is building as I type ;-) Once
I have that built, I'll see about a patch to get the necessary changes in for
the NetStation.

Rgds,
John...
