[ros-dev] How does one make a MP build anyway?

[WaxDragon]

Gang,

   I have been unsuccessful in building a working MP bootcd for a
while now.  I conferred with Hartmut about some of the details, but
still cannot get it working.

This is what I tried:

1. Set MP=1 in config.xml
2. Hacked the hal xml files to make halmp.dll hal.dll on the bootcd, per Harmut

3. make bootcd, as normal

The resulting bootcd fails to boot under "qemu -smp 2" with the following

An MP bootcd I made several months ago (~18xxx) did the same thing on
a Abit BP6 with dual Celerons, so I'm fairly confident qemu is acting
properly.  I still have the BP6 and am willing to test MP builds, but
I wasted about 10 CD-R's trying to get a working MP bootcd before
giving up.

Am I just doing something wrong?  I would like to get this worked out
and documented somewhere.
