Oh great info, but I spend three nights to get it work and haven't success.

TILO:
I use silo 1.4.13 compile without problem. I take compiled kernel which boot OK 
on my Ultra 5 and create small cramfs ramdisk with bash as init in /sbin + 
library. root.img is ~1.2M.

I run



./tilo/tilo.sh vmlinux ram_image.gz
Converting vmlinux (sun4u) to a.out:
PT 0 Entry: Loadable to 0x400000[0x3c2c30] from 0x0[0x354086] align 0x100000
PT 1 Entry: unknown
Compressing vmlinux.raw:
vmlinux.raw:     54.6%
Sizes (sun4u):
   raw size     = 3473542
   packed size  = 1575482
   root address = 00000000007c2c30
Root image packed size = 1085472
WARNING: Kernel for Sun4c/m/d not specified
Images are large. Will load on machines with at least 5M mapped by PROM only
TILO size = 2678102

But when I boot after loading boot stops with Illegal instruction :-(
If ram_image is smaller system boots but I need approx 2M is it possible ?


PIGGYBACK:

/usr/bin/piggyback vmliuz.aout sys_map.gz ram_image
Could not determine start and end from System.map
And nothing else. I look to piggyback.c and see then it search end statement not 
_end. I modify this but get sigsegv.

  /usr/local/bin/piggyback vmlinuz.aout System.map root.img
Start : 0x404000 End: 0x722ca4
i:137032
lseek: Invalid argument
lseek 2: Illegal seek

I search over whole world and nothing. I have large experience with i86 netboot 
but with Sun I start now :-).
