MotLoad actually netboots fine, but AFAIK it doesn't boot from flash (a 
capability I already have gladly exploited with the MVME2100 and the 
PPCbug). While it seems that a lot of setups often seem to be perfectly 
ok with a netboot (which seems to be very popular with VxWorks as well), 
for my setup a flash boot setup would really be the better choice - 
especially since on the MVME5500 flash is an abundant resource: 32-40MB 
are more than enough for a really nice root filesystem, don't you think? 
(I've not even ran out of the 4MB on the MVME2100 by now - thanks, 
uClibc and BusyBox!!!)

Well, as long as the Linux vendors either hide their Linux kernels, or 
release only trimmed down versions of them (and no patchset), I guess 
the bootloader is not the worst problem - ok, ok, of course to people on 
this list this is actually an issue at heart!! But with all the closed 
mailing lists, and proprietary patchsets for customers only, open-source 
projects seem to be pretty much to be on the exploited side of the deal 
to me. :(

This is of course a general comment, and not about your special SDK 
vendor, which I have no experience with yet!

Thanks, and with kind regards,
