hi stephan-
i do not think writing drivers to access the hardware will be much
of a problem (at least not after the recent code clean up).
i am not very familiar with OS9. does the OS9 prom totally replace
the bug proms, or is it in there in addition to the bug proms?
at any rate, i don't think it should be too hard to convert the stand
alone code and the kernel to use a different PROM. seems like all you'd
have to do is make a version of netboot that uses the OS9 prom, and then
have a flag passed to the kernel to let it know it was booted from a different
kind of prom (kind of like the RB_SBOOT flag I put in recently).
on a unrelated note, i have converted the sun3 "ramdisk" and "miniroot"
set up to the mvme68k. i am currently working on the details of booting
from the "swap" area of a disk. this will allow installation directly to
disk (you can either use sboot, or download the "ramdisk" kernel over the
serial line to get started).
